x-2/5=2/3-3x-2/6
Answer:
11/48
Step-by-step explanation:
x-2/5=2/3-3x-2/6
collect like terms
x-2/5 + 3x = 2/3 - 2/6
taking LCM on both sides
[(x-2) + 5(3x)]/5 = [2(2) -2]/6
(16x - 2)/5 = 2/6
cross multiply
6(16x - 2) = 5(2)
96x - 12 = 10
96x = 22
therefore; X = 22/96
= 11/48
CHECK:
(11/48 - 2)/5 = 2/3 - 3(11/48) - 2/6
(-85/48)/5 = 2/3 - 11/16 - 2/6
-85/48 × ⅕ = -17/48
-17/48 = -17/48
Answer:
[tex]x=\frac{11}{60}[/tex]
Step-by-step explanation:
Given the equation
[tex]x-\frac{2}{5}=\frac{2}{3}-3x-\frac{2}{6}[/tex]
Lets solve for x.
Simplify the right side of the equation.
Cancel the common factor of 2 and 6 .
Factor 2 out of 2 .
[tex]x-\frac{2}{5}=\frac{2}{3}-3x-\frac{2(1)}{2(3)}[/tex]
[tex]x-\frac{2}{5}=\frac{2}{3}-3x-\frac{1}{3}[/tex]
Combine the numerators over the common denominator.
[tex]x-\frac{2}{5}=-3x-\frac{2-1}{3}[/tex]
[tex]x-\frac{2}{5}=-3x-\frac{1}{3}[/tex]
Move all terms containing x to the left side of the equation.
Add [tex]3x[/tex] to both sides of the equation.
[tex]x-\frac{2}{5}+3x=\frac{1}{3}[/tex]
Add [tex]x[/tex] and [tex]3x[/tex].
[tex]4x-\frac{2}{5}=\frac{1}{3}[/tex]
Move all terms not containing x to the right side of the equation.
Add [tex]\frac{2}{5}[/tex] to both sides of the equation.
[tex]4x=\frac{1}{3}+\frac{2}{5}[/tex]
To write [tex]\frac{1}{3}[/tex] as a fraction with a common denominator, multiply by [tex]\frac{5}{5}[/tex] .
[tex]4x=\frac{1}{3}*\frac{5}{5} +\frac{2}{5}[/tex]
To write [tex]\frac{2}{5}[/tex] as a fraction with a common denominator, multiply by [tex]\frac{3}{3}[/tex]
[tex]4x=\frac{1}{3}*\frac{5}{5} +\frac{2}{5}*\frac{3}{3}[/tex]
Simplify.
Write each expression with a common denominator of 15 , by multiplying each by an appropriate factor of 1 .
[tex]4x=\frac{11}{15}[/tex]
Divide each term in [tex]4x=\frac{11}{15}[/tex] by 4 and simplify.
[tex]x=\frac{11}{60}[/tex]
A telecommunications company will be laying new fiber optic cables underground. One cable will be perpendicular to the road shown, passing through the point ( 7, 2 . At what point will the cable pass through the road?
The point at which this cable would pass through the road shown is at the y-intercept of (0, -17/2).
How to determine an equation and the point on this perpendicular line?Mathematically, the slope of a straight line can be calculated by using this formula;
Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Slope, m = (y₂ - y₁)/(x₂ - x₁)
By critically observing the road shown in the graph above, the points on the line include the following:
Points (x, y) = (0, -2)
Points (x, y) = (-3, 0)
Substituting the given points into the formula, we have;
Slope, m = (0 + 2)/(-3 - 0)
Slope, m = 2/-3
Slope, m = -2/3.
In Mathematics, a condition that must be met for two lines to be perpendicular is given by:
m₁ × m₂ = -1
-2/3 × m₂ = -1
-2m₂ = -3
m₂ = 3/2
At point (7, 2), a linear equation for the line can be calculated by using the point-slope form:
y - y₁ = m(x - x₁)
Where:
m represents the slope.x and y represent the points.c represents the y-intercept.Substituting the given points into the formula, we have;
y - 2 = 3/2(x - 7)
y - 2 = 3x/2 - 21/2
y = 3x/2 - 21/2 + 2
y = 3x/2 - 17/2
At the y-intercept of (0, -17/2), the cable pass through the road.

The scale of a map is 1:20 000. What area does 8 cm² represent?
The 8 cm² area on a map represent the actual area = 3200000000 cm² .
Scale factor of a map
S = 1/20000
The scale factor for area is found by squaring the scale factor for length. Thus the scale factor for area is S^2
When applied to the area we consider S^2 as a scale factor.
The area on the map = 8 cm²
So The actual area = 8 × (20000)^2 = 8× 20000×20000
=3200000000 cm² = 320000 m² =32 hectare.
So the 8 cm² area on a map represent the actual area = 3200000000 cm² .

-6.6 < 1.7 + u Solve the inequality for u.
Simplify your answer as much as possible.
Solving the inequality -6.6 < 1.7 + u for u, the solution is simplified as: u > -8.3 or -8.3 < u.
What is an Inequality?In maths, an inequality is defined as a statement that is used to compare two quantities that are unequal. For example, we can state that 5 is greater than 3 + 1, or 5x is less than 4x + 3x. We can equally state that a given value of a variable can be equal to or greater than a number, and so on.
Basically, we are comparing two unequal quantities when we state inequalities.
Given the inequality, -6.6 < 1.7 + u, we are asked to solve the inequality for u. That is, we need to find the possible value that u represents in the inequality or that would make the inequality true.
Therefore:
-6.6 < 1.7 + u
Subtract 1.7 from both sides
-6.6 - 1.7 < 1.7 + u - 1.7 [subtraction property of equality]
-8.3 < u

Answer:
about 21.3 cm²
Step-by-step explanation:
Given a triangle with three sides 6 cm, 8 cm, and 12 cm, and smallest angle 26.4°, you want the area.
Area using sine formulaA = 1/2ab·sin(C)
A = 1/2(12 cm)(8 cm)·sin(26.4°) ≈ 21.34 . . . . square units
Area using Heron's formulaThe semiperimeter is ...
s = (6 +8 +12)/2 = 13
The area is ...
A = √(s(s -a)(s -b)(s -c))
A = √(13·(13 -12)(13 -8)(13 -6)) = √(13·1·5·7) = √455
A ≈ 21.33 . . . . square centimeters
The area of the triangle is about 21.3 cm².

Additional comment
The problem with over specifying the dimensions of a geometry problem is that it is often difficult to make them consistent. Here, the area values agree to three significant figures. That is about all we can expect, given the angle precision is 3 significant figures.
Your answer depends on the set of dimensions you choose to use. It will be different yet if you use the Law of Sines to find angle A or B for the Sine Formula, especially if you round the angle value to tenths.

As per given information about change in uplift it occurs at the rate of 0.1 m per 1,000 years then change in uplift over 1,000,000 years is equal to 100m.
As given in the question,
Rate of occurring of uplift is equal to 0.1m per 1000 years
Represent the given relation in equality form we get,
Change of uplift in 1000 years = 0.1 m
⇒ 1 year = 0.1 m / 1000
⇒ 1,000, 000 years = ( 0.1 m / 1,000 ) × 1,000, 000
⇒ 1,000, 000 years = ( 1 m / 10,000 ) × 1,000, 000
⇒ 1,000, 000 years = 100 m
Therefore, for given information about change in uplift it occurs at the rate of 0.1 m per 1,000 years then change in uplift over 1,000,000 years is equal to 100m.

In one day, the bakery made 719 bagels. The bagels were divided into 9 equal shipments. A few bagels
were left over and given to the baker. How many bagels did the baker get?
Answer:
8 bagels
Step-by-step explanation:
This is a remainder division problem. We need to divide 719 by 9 and find the remainder.
First off, 9 is bigger than 7, so we need to move to the next digit. How many times does 9 go into 71? 9 times 7 is 63! That's the closest smaller number we can get, so I will write a 7 in the long division problem above the 1. I will subtract 63 from 71 to get 8.
7
9 | 719
-63
8
Now, the 9 can be brought down, making our 8 into an 89. How many times does 9 go into 89? 9 times 9 is 81! That's the closest we can get! I will write a 9 by the 7 above the 9 in 719, and write 81 below the 89. Subtracting these leaves us with a remainder of 8.
79
9 | 719
-63 ↓
89
-81
8
This means that the bagels were sent in 9 equal shipments of 79 bagels each, and the baker was left with 8 bagels!

A graph can be vertically translated by moving the base graph up or down in the y-axis direction. Each point on a graph is moved k units vertically to translate the graph by that many units.The rules for transforming a function f(x) into g(x):

it takes an airplane 1 hour 30 minutes to fly 600 km against the wind. the return trip with the wind takes only 1 hour. find the total flying time for the round trip if there was no wind.
The total flying time for the round trip if there was no wind would be 2 hours 24 minutes. The result is obtained by using the elimination method.
What is elimination method?The elimination method is a method for solving system of linear equations where we eliminate one variable so that we can get an equation in one variable. In doing that, we can either add or subtract the equations.
Given the case that an airplane takes 1 hour 30 minutes to fly 600 km against the wind. It takes only 1 hour in the return trip.
What would be the total flying time for the round trip if there was no wind?
Let's say:
v = the speed of the airplanew = the speed of the windWhen the airplane leaves,
v - w = 600 km / 1.5 hour
v - w = 400 kph ... (equation 1)
When the airplane returns,
v + w = 600 km / 1 hour
v + w = 600 kph ... (equation 2)
We eliminate the equation 2 and 1 to get the speed of the airplane.
v - w = 400 kph
v + w = 600 kph +
2v = 1000 kph
v = 1000 ÷ 2
v = 500 kph
For the round trip, the airplane would fly 600 × 2 = 1200 km.
The total flying time if there was no wind would be
t = s/v
t = 1200/500
t = 2.4 hour
t = 2 hours 24 minutes
Hence, the total flying time for the round trip if there was no wind is 2 hours 24 minutes.
