Answer:

x = 14/3

y = 16.3333333333

Step-by-step explanation:

Step 1. equal them to each other and solve for x

2x + 7 = 5x - 7

5x - 2x = -14

3x = 14

x = 14/3

Step 2. Plug in the value of x and solve for y

y = 5x - 7

y = 16.3333333333

Answer:

x= 14/3

y= 49/3

Step-by-step explanation:

y= 2x+7

y= 5x-7

-2x + y = +7

(-5x + y = -7) * (-1)

-2x + y = +7

+5x - y = +7

3x +0y= 14

3x= 14

x= 14/3

replace x in any equation from these 2:

y= 2x+7

y= 5x-7

ill chose this :

y= 2x+7

y= 2(14/3) +7

y= 49/3

The perimeter of a triangle is 27 feet. One side is 3 feet longer than the shortest side, and the longest side is twice as long
dangina [55]

Answer:

6, 9, 12

Step-by-step explanation:

Let s be the shortest side. Using the information you're given, you can create an equation. 27= s + s+3 + 2s. Now just solve the equation. Subtract 3 from both sides. 24=4s. Divide by 4 on both sides. 6=s. So the shortest side is 6 feet long, so we add 3 to that for the one that is neither the shortest or the longest. That side is 9 feet long. We double s to get 12, which is the longest side.

A side of a square is 8 3/2  inches. Using the area formula A = s2, determine the area of the square.
Sedaia [141]
We are given that:
side length = 8 3/2 inches = 9.5 inches
the rule for the area is: A = s^2

Substitute with the side length in the rule given to get the area as follows:
Area = s^2 = (9.5)^2 = 90.25 inch^2
