Please someone help who is actually good at math

-36p+23q-10r

Step-by-step explanation:

It just says to simplify, meaning you just need to combine like terms.

-5 x 9p = -45p

-5 x -4q = 20q (negatives cancel out each other)

-5 x 2r = -10r

after that you combine like terms:

9p + (-45p) = -36p

3q + 20q = 23q

there is no other term that can go into r, so you just leave it as it is.

so the final answer comes to -36p+23q-10r

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

∠cbe and ∠deb are same-side interior angles.
