2a-5b=10 solve for b

1 answer:

4 0

Solve for b means that you need to separate b in one side and the other terms in the other side

2a-5b=10 subtract 2a from both sides

2a - 5b - 2a = 10 - 2a combine like terms

- 5b = 10 - 2a divide both sides by -5

b = -2 + 2/5 a

I hope that helps!

Please help solve for PQ.

DerKrebs [107]

This problem cannot be solved unless we are given figure NPQR is a rhombus.
In that case, then all sides are equal, meaning
5x+16=9x-32
Solve for x
9x-5x=16+32
4x=48
x=12

Each side (including PQ) then equals 5x+16=5*12+16=76
