75 always do parenthesis first so 5*3=15 so 15x5=75 because 5*5=25 so drop the 5 carry the 2 the do 5*1 which equal 5 then add 2 and that equal 75.
4p+2c=54
4p+2(21-p)=54
4p+42-2p=54
2p+42=54
2p=12
p=6
4p+2c=54
4(6)+2c=54
24+2c=54
2c=30
c=15
p=6, c=15
Answer choice C is correct
you take 99 divided by 22 = 4.5
I don't understand what exactly your teachers meaning so I would also suggest asking but the answer compered to everything I've learned in math would be 4.5.
have a good day/night!! :)
