Step-by-step explanation:
What value of R makes r/ -11 = (-3) true
Answer:
The value of [tex]r=33[/tex] which makes the equation true.
Step-by-step explanation:
Given the equation
[tex]\frac{r}{-11}=-3[/tex]
We have to find the value of r for which the equation must be true.
solving the equation
[tex]\frac{r}{-11}=-3[/tex]
Multiply both sides by -11
[tex]\frac{r\left(-11\right)}{-11}=\left(-3\right)\left(-11\right)[/tex]
[tex]r=33[/tex]
Therefore, the value of [tex]r=33[/tex] which makes the equation true.
VERIFICATION:
Putting [tex]r=33[/tex] in the equation
[tex]\frac{r}{-11}=-3[/tex]
[tex]\frac{33}{-11}=-3[/tex]
[tex]-3=-3[/tex] ∵ [tex]\frac{33}{-11}=-3[/tex]
L.H.S = R.H.S
Therefore, the value of [tex]r=33[/tex] which makes the equation true.

Which equation is equivalent to y = -9/4(x - 8) + 6 when solved for x?
Answer:
X = -4Y/9 + 32/3
Step-by-step explanation:
you can solve for X by simplifying both sides of the equation then isolating the variable
The value of the given equation y = -9/4(x - 8) + 6 for the x will be x = -(4/9)y + 96/9
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.
A formula known as an equation uses the same sign to denote the equality of two expressions.
In another word, the equation must be constrained with some constraints.
Given the equation,
y = -9/4(x - 8) + 6
By taking LCM in right-hand side
y = [-9(x - 8) + 24]/4
Cross multiply
4y = -9(x - 8) + 24
Interchange
9(x - 8) = 24 - 4y
9x - 72 = 24 - 4y
x = (4/9)y + 96/9
Hence "The value of the given equation y = -9/4(x - 8) + 6 for the x will be x = -(4/9)y + 96/9".

A side of the triangle below has been extended to form an exterior angle of 125°. Find the value of X
Answer:
x = 19°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, thus
x + 106° = 125° ( subtract 106° from both sides )
x = 19°
The basketball team spends 20 minutes running laps and at least 15 minutes discussing plays. Practice lasts one hour and 45 minutes. Write an inequality to represent the amount of time to work on other drills. Just type in the final answer. Let: x=other drills
Answer:
x ≤ 75
Step-by-step explanation:
The computation of the inequality function is as follows:
Let us assume the remaining time left for other drills be x
Given that the team spends 20 minutes for running laps
And minimum of 15 minutes for discussing plays
Also practicing for last one hour and 45 minutes
Now as we know that
1 hour = 60 minutes
So total minutes would be
= 60 + 45
= 105 minutes
Total minutes spend by the team is
= 20 + 15
= 35 minutes
So now the remaining time left is
x ≤ 105 - 35
x ≤ 75
A washer and a dryer cost $834 combined. The washer costs $84 more than the dryer. What is the cost of the dryer?
Answer:
The dryer cost $375
Step-by-step explanation:
834/2 = 417
84/2 = 42
417 - 42 = 375
834 - 375 = 459
459 - 84 = 375
PROOF: 417 - 375 = 42 then double that answer to get 84

On Monday, I bought 2 shirts and 6 pairs of pants for a total cost of $11. On
Tuesday, I bought 5 shirts and 8 pairs of pants for a total cost of $18.75. Can you
find the price of each item?
Step-by-step explanation:
Step one:
given data
let the shirts be x
and the pants be y
Required
the number of shirts and pants
the systems of the equation for the situation is
2x+6y=11-------------1
5x+8y=18.75-------2
2x+6y=11-------------1X 5
5x+8y=18.75-------2 X2
10x+30y=55-------------1
-10x+16y=37.5-------2
0x+14y=-17.5
divide both sides by 14
y=17.5/14
y=1.25
pants= $1.25
put y=2.32 in eqn 1 2x+6y=11
2x+6(1.25)=11
2x+7.5=11
2x=11-7.5
2x=3.5
x=3.5/2
x=$1.75

The sand pit for the long jump has a width of 2.7 meters and a length of 9.54 meters. Just in case it rains, the principal wants to cover the sand pit with a piece of plastic the night before the event. How many square meters of plastic will the principal need to cover the sand pit?
Answer:
A = 25.758 m²
Step-by-step explanation:
Width of the sand pit, b = 2.7 m
Length of the sand pit, l = 9.54 m
We want to cover the sand pit with a piece of plastic. We need to find how many square meters of plastic will be needed to cover the sand pit. It is equal to the area of sand pit. It is in the shape of rectangle. Its area is given by :
A = l × b
A = 2.7 × 9.54
A = 25.758 m²
So, 25.758 m² of plastic will be needed to cover the sand pit.

Step-by-step explanation:
✔️Finding length of side s using:
[tex] cos(\theta) = \frac{adjacent}{hypotenuse} [/tex]
Where,
[tex] cos(\theta) = cos(60) = \frac{1}{2} [/tex]
Adjacent = s
Hypotenuse = 8
Plug in the values
[tex] \frac{1}{2} = \frac{s}{8} [/tex]
Multiply both sides by 8
[tex] \frac{1}{2} \times 8 = \frac{s}{8} \time 8 [/tex]
[tex] \frac{8}{2} = s [/tex]
[tex] 4 = s [/tex]
s = 4
✔️Finding length of side q using:
[tex] sin(\theta) = \frac{opposite}{hypotenuse} [/tex]
Where,
[tex] sin(\theta) = sin(60) = \frac{\sqrt{3}}{2} [/tex]
Opposite = q
Hypotenuse = 8
Plug in the values
[tex] \frac{\sqrt{3}}{2} = \frac{q}{8} [/tex]
Multiply both sides by 8
[tex] \frac{\sqrt{3}}{2} \times 8 = \frac{q}{8} \times 8 [/tex]
[tex] \frac{\sqrt{3}}{1} \times 4 = q [/tex]
[tex] 4\sqrt{3} = q [/tex]
[tex] q = 4\sqrt{3} [/tex]

A population of bees is decreasing. The population in a particular region this year is 1250. After year 1, it is estimated that the population will be 1000. After 2 years it is estimated that the population will be 800. How many years will it take for the bee to be below 100?
Answer:
1250 => 250 ( subtracted from the balance population )
1000 => 300
800 => 350
450. => 400
50.
So it will take around 5 years I think to be below 100.

Answer:
a8 = 512.
Step-by-step explanation:
This is geometric sequence with common ratio r = 2 and first term a1 = 4.
nth term = a1 r^(n-1)
So a8 = 4 2(^8-1)
= 4 * 2^7
= 4*128 = 512.

Your dad is designing a new garden for your backyard. He has 20 feet of fencing to go around the garden. He wants the length of the garden to be 2 1/2 feet longer than the width. How long should he make the garden?
Answer:
Length = 6.25 feet
Step-by-step explanation:
Your dad is designing a new garden for your backyard. He has 20 feet of fencing to go around the garden.
Let the width is x.
Length is 2 1/2 feet longer than the width i.e. (x+2 1/2) = (x+2.5) feet
Perimeter = 20 feet
2(l+b) = 20
(l+b) = 10
(x+2.5+x) = 10
2x+2.5 = 10
2x = 7.5
x = 3.75 feet
Length = (x+2.5)
= (3.75+2.5)
= 6.25 feet
So, the length of the garden is 6.25 feet.
A car is traveling at a steady speed. It travels 1 3/4 miles in 2 1/3 minutes. How far will it travel in 45 minutes? In 1 hour?
Answer:
33.75 miles in 45 minutes,
45 miles in an hour
Step-by-step explanation:
45 minutes: 2 1/3= 7/3 ---> 7/3*3=7,
1 3/4= 7/4 ---> 7/4*3=5.25
car travels 5.25 miles for every 7 minutes,
45/7*5.25= 33.75 miles
1 hour (60 minutes):
using that the car travels 5.25 miles for every 7 minutes,
60/7*5.25= 45 miles
