The model represents an equation. what value of x makes the equation true?
a)
3
4
b)
9
2
c) −
3
4
d) −
9
2

  B)  9/2

Step-by-step explanation:

Subtracting 5x+7 from both sides leaves 2x = 9.

Dividing the 9 into two parts, we find ...

  x = 9/2

the amount you'd have after the work is $1.55

step-by-step explanation:

you subtract 95% from $31.

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:
