Let's represent the number of hours with the variable 'h' (or whatever letter you want it to be):
265 + 48h = 553
Substract both sides by 265:
48h = 288
Divide:
h = 6
6 hours of labor was spent
Answer:
I think it is -10
Step-by-step explanation:
Using a^m*a^n=a^(m+n)
b=(m+n)
In this question,
m= -8 and n= -2
so b= (m+n)=(-8+-2) = -10
Can you speak English??? if so i dont talk spanish
1- I didn't understand it
2).. (a/b)² (a/b)⁸
= (a/b)²+⁸ = (a/b)¹⁰
3) 3-⁵ = 1/3⁵ = 1/243
4) (x/y)"
d/dx (x/y) = (1/y)
d/dx (1/y) = 0
5) (2m⁴n³)⁵
= 2⁵ × (m⁴)⁵ × (n³)⁵
= 32 × m²⁰ × n¹⁵
= 32m²⁰n¹⁵
It’s 45, as the equation for a parallelogram is A= bxh, and 9x5 is 45
