Answer: See explanation
Step-by-step explanation:
The perimeter of a pentagon is gotten through the summation of its five sides. Let the first side be represented by x. Since each side of a pentagon is 10 cm greater than the previous side, then the sides will be:
First side = x
Second side = x + 10
Third side = x + 10 + 10 = x + 20
Forth side = x + 30
Fifty side = x + 40
Therefore,
x + (x + 10) + (x + 20) + (x + 30) + (x + 40) = 500
5x + 100 = 500
5x = 500 - 100
5x = 400
x = 400/5
x = 80
Therefore, the lengths will be:
First side = x = 80cm
Second side = x + 10 = 80 + 10 = 90cm
Third side = x + 20 = 80 + 20 = 100cm
Forth side = x + 30 = 80 + 30 = 110cm
Fifty side = x + 40 = 80 + 40 = 120cm
Answer:
Your answer is Division Property of Equality
Step-by-step explanation:
It <em>could</em> be Addition Property of Equality, but the second number shows it is actually the division property of equality. Here's my work:
-4x + 6y = 12 Given
(-4x/2) + (6y / 2) = (12/2)
--Simplify--
−2x + 3y = 6
Sidenote: I'm doing the test right now haha
