Answer 1

$p) 9*(-5)+28:(-7)= \\ \\ -45+(-4)=-45-4= \boxed{49} \\ \\ q)(800:10):(30:3)+75:15-2^2= \\ \\ 80:10+5-4=8+5-4= \boxed{9}$

Espero que te sirva, salu2!!!!

Answer 2

P=9X(-5)+28÷ (-7)
P= (-45) + (-4)
P=49
Q=(800÷ 10)÷ (30÷ 3)+75÷ 15-2 ²
Q=80 : 10 + 5 - 4
Q= 8+5-4
Q=13-4
Q=9
P+Q= 49 +9
P+Q= 58
