Answer:
x = -2
Step-by-step explanation:
14 - (x + 5) = 3(x + 9) - 10
14 - x - 5 = 3x + 27 - 10
9 - x = 3x + 17
9 = 4x + 17
-8 = 4x
-2 = x

Hi there!
We are looking for the circumference of the school field. When we assume that the field is a rectangle, we can use the following formula for finding its circumference.
Circumference = 2 × length + 2 × width
Plug in the length and width from the question.
Circumference = 2 × 50 + 2 × 10
Multiply first (remember: PEMDAS).
Cirxumference = 100 + 20
And finally add.
Circumference = 120.
Hence, the total length of the fence will be 120 meters.
~ Hope this helps you!
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
