How do you solve this7x+2y=180
Amanda [17]

Answer:

Step-by-step explanation:

Simplifying

7x + 2y = 180

Solving

7x + 2y = 180

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2y' to each side of the equation.

7x + 2y + -2y = 180 + -2y

Combine like terms: 2y + -2y = 0

7x + 0 = 180 + -2y

7x = 180 + -2y

Divide each side by '7'.

x = 25.71428571 + -0.2857142857y

Simplifying

x = 25.71428571 + -0.2857142857y

135

Step-by-step explanation:

Prism

volume= area of base times distance between your 2 bases

v=bh/2

i did  b=area of base, h=height , v=volume , 1/2...so i believe that you take 6 and multiply it by 5 which equals 30 then you multiply the 30 by 9 and i got 270 then i divide by 2... so 270/2 which equals 135..so the answer is 135

(for a rectangular shape its just length times height
