Step-by-step explanation:
If DF=70, find the value of x.
Answer:
x = 12
Step-by-step explanation:
DE + EF = DF
2x - 1 + 5x - 13 = 70
7x - 14 = 70
7x = 70 + 14
= 84
x = 84 ÷ 7
x = 12
Answer: x=12
Step-by-step explanation:
2x-1+5x-13=70
Combine like terms
7x-14=70
Add 14 to both sides
7x=84
Divide both sides by 7
X=12

What are Periodic tables
AB formed by (0-2) and (0,7)
CD formed by (3,-5) and (6,-5)
Answer:
AB is undefined, CD is y = -5
Step-by-step explanation:
Find both of the line's slopes. You can use the formula for slope to calculate this answer because you know two points on the line for both lines (Look below). If you plug in the points for AB, you would have ( -2 - 7)/0, which would be undefined, because anything divided by 0 is undefined. Since the slope for AB is undefined, it is undefined. Next, we have CD. If you plug in the points for CD, you would get (-5 - (-5))/(6 - 3), which would be 0/3, which is 0. This means that the slope is 0. Next, we have to plug in the points for CD into the formula for equation of the line (Look Below), which would be y - (-5) = 0 * (x - 6), which simplifies to y + 5 = 0, which is y = -5.
Formula for Slope:
[tex]\frac{y1 - y2}{x1 - x2}[/tex]
Usable with 2 points of the line given ((x1, y1) and (x2, y2))
Formula for Equation of the Line:
[tex]y - y1 = slope * (x - x1)[/tex]
Usable with the slope and a point given ((x1, y1))
Answer: AB is undefined (AB is not a relationship, slope is undefined (Vertical Line)) and CD is y = -5 (Horizontal Line)

If the measure of two sides of the triangle are 3 feet's and 7 feet's, which is the least possible whole number measure for the third side
Answer:
5 feet
Step-by-step explanation:
By triangle inequality, the sum of lengths of any two sides has to be strictly greater than the length of the third side.
Let x feet be the length of the third side.
We have 3+x>7, x+7>3 and 3+7>x.
Solving these, we get x > 4, x > -4 and x < 10.
The solution is therefore 4 < x < 10 and the smallest whole number which satisfies the inequality is 5.
Therefore the answer is 5 feet.

On a certain day the temperature in Austin was 10.2°C and the temperature in New York City was -4.8°C. What is the difference in temperature between the two cities?
Show your work please and if you do you get 60 points!!!!
good luck and please don't get the wrong answer. it took me a long time to get the points so please and good luck!
Answer:
15°C
Step-by-step explanation:
Find the difference by subtracting -4.8 from 10.2
10.2 - (-4.8)
Subtracting a negative number changes to adding a positive number:
10.2 + 4.8
= 15
So, the difference in temperature between the two cities is 15°C
what is the vaule of m in the expression m^2(2-3m)-6m(1-4m+5m^2)
Answer:
1 ( 12-3m ) - 5m ( 11-4m+25)
1 ( 9m ) - 5m ( 32m )
9m -5m ( 32m )
4m ( 32m )
32×4 = 128 m
128 m
Answer:
Without an equivalence given (i.e. an equals sign somewhere in the expression), we have no way of solving for m.
We can however simplify it:
m²(2 - 3m) - 6m(1 - 4m + 5m²)
= 2m² + 3m³- 6m + 24m² - 30m⁴
= 26m² + 3m³ - 6m - 30m⁴
= m(-30m³ + 3m² + 26m - 6)
Daniela ha comprado 2,5 kg de naranjas a un precio de 1,75 € el kg, 1,5 kg de manzanas a 1,6 el kg y 1,5 kg de plátanos a 1,25 € el kg . Si juntamos toda la fruta en la misma bolsa , ¿cuál es su peso ? ¿ cuanto ha pagado Daniela por toda la fruta ?
Answer:
a) 5,5kg
b) 8,65 €
Step-by-step explanation:
Daniela ha comprado 2,5 kg de naranjas a un precio de 1,75 € el kg, 1,5 kg de manzanas a 1,6 el kg y 1,5 kg de plátanos a 1,25 € el kg.
a) Si ponemos toda la fruta en la misma bolsa, ¿cuál es su peso?
Naranjas = 2,5 kg
Manzanas = 1,5 kg
Plátanos = 1,5 kg
Por lo tanto:
El peso total
= Peso de las naranjas + Peso de las manzanas + Peso de las bananas
= 2,5 kg + 1,5 kg + 1,5 kg
= 5,5 kg
b) ¿Cuánto ha pagado Daniela por toda la fruta?
Costo de las naranjas
Daniela ha comprado 2,5 kg de naranjas a un precio de 1,75 € el kg
1 kg = 1,75 €
2,5 kg = x
x = 2,5 × 1,75 €
x = 4,375 €
Costo de las manzanas
1,5 kg de manzanas a 1,6 € el kg
1 kg = 1,6 €
1,5 kg = x
Cruz multiplicar
x = 1,5 × 1,6 €
x = 2,4 €
Costo de los plátanos
1,5 kg de plátanos a 1,25 € el kg.
1 kg = 1,25 €
1,5 kg = x
Cruz multiplicar
x = 1,5 × 1,25 €
x = 1.875 €
La cantidad que Daniela pagó por toda la fruta es:
4,375 € + 2,4 € + 1,875 €
= 8,65 €

A travelers ground speed is 2 feet per second against the walkway and 8 feet per second with the walkway, what is the travelers speed off the walkway, what is the speed of yhe walkway
Answer:
The traveller's speed is 5ft/s and the walkway speed is 3ft/s
Step-by-step explanation:
Given
Represent the traveller's speed with T and the walkway's speed with W.
When the traveller walk against the walkway, we have:
[tex]T - W = 2[/tex] ---- i.e. 2ft/s against the walkway
When the traveller walk with the walkway, we have:
[tex]T + W = 8[/tex] ---- i.e. 8ft/s with the walkway
Required
Solve for W and T
[tex]T - W = 2[/tex] --- (i)
[tex]T + W = 8[/tex] --- (ii)
Add (i) and (ii)
[tex]T + T - W + W = 2 + 8[/tex]
[tex]T + T = 2 + 8[/tex]
[tex]2T = 10[/tex]
Divide both sides by 2
[tex]\frac{2T}{2} = \frac{10}{2}[/tex]
[tex]T = \frac{10}{2}[/tex]
[tex]T = 5[/tex]
Substitute 5 for T in (ii)
[tex]T + W = 8[/tex]
[tex]5 + W = 8[/tex]
Make W the subject
[tex]W = 8 - 5[/tex]
[tex]W = 3[/tex]
Hence, the traveller's speed is 5ft/s and the walkway speed is 3ft/s

Julien is baking cookies with his mother.
The recipe calls for:
1 ½ cups of flour
2 ⅔ cups of oatmeal
3 ¼ cups of chocolate chips
1 cup of sugar
½ cup of brown sugar
The only measuring cups that Julien can find are ⅛ cup and ⅓ cup. How will he make the cookies?
Answer:
well quite easily just doing the math
Step-by-step explanation:
Ta -Da
1 1/2 cups of flour = 12/8 cups of flour
2 2/3 cups of oatmeal = 2 2/3 cups of oatmeal
1 cup sugar = 3/3 or 8/8 cups of sugar
1/2 cup of brown sugar = 4/8 cups of brown sugar
H varies directly to the cube of c.
When H = 40, C = 2.
Find the value of H when c=5
Answer:
H = 625
Step-by-step explanation:
Given H varies directly as c³ then the equation relating them is
H = kc³ ← k is the constant of variation
To find k use the condition when H = 40, c = 2, then
40 = k × 2³ = 8k ( divide both sides by 8 )
5 = k
H = 5c³ ← equation of variation
When c = 5, then
H = 5 × 5³ = 5 × 125 = 625
Michele wanted to measure the height of her school's flagpole to place on the ground 35 ft from the flagpole then walks backwards until she was able to see the top of the pole in the mirror her eyes were 5 feet above the ground and she was 12 ft away from the mirror using similar triangles, find the height of the flagpole to the nearest of a foot
Answer:
15 feet
Step-by-step explanation:
Michele wanted to measure the height of her school's flagpole to place on the ground 35 ft from the flagpole then walks backwards until she was able to see the top of the pole in the mirror her eyes were 5 feet above the ground and she was 12 ft away from the mirror using similar triangles, find the height of the flagpole to the nearest of a foot
Using similar triangles
= Let the height of the flagpole be represented as h.
h/35 =5/12
We cross Multiply
35 x 5 = 12h
12h = 175
h = 175/12
h = 14.583333333 feet
Approximately to the nearest foot is
h = 15 feet

2x+y=-2
5x+3y=-4
Answer:
x=-2,y=2
Step-by-step explanation:
2x+y=-2 ----> y=-2-2x----(1)
25x+3y=-4 ---(2)
Replace (1) in (2)
5x+3(-2-2x)=-4
5x-6-6x=-4
-x=-4+6
-x=2
x=-2
If x=-2,then replace x in (1)
y=-2-2(-2)
y=-2+4=2

Plsssss help??? Also do any of u know a graphing app that shows u the points and were to put them?
Answer:
See below
Step-by-step explanation:
There are two ways to graph an equation.
1st Way:
We can use a graphing calculator. (See the attached file)
2nd Way:
We can take the values of x as 0, 1 , 2 (Or anything).
Then, We have to put the values of x in the equation to get the value of y accordingly.
According to these values, Plot the graph.
Also,
Slope = 5 / 6
y-intercept = 1
