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
Answer:
150
Step-by-step explanation:
'x' = number of students out of 500 who selected math
18/60 = x/500
cross-multiply:
60x = 9000
x = 150
Answer:

Step-by-step explanation:
The sum already has common denominators so there is no need to change the denominators. Just add the numerators.


<span>-8x-3(1+2x)
= </span><span>-8x -3 - 6x
= -14x - 3</span>
4p+6=t
2(2p+3)=t
t/4 - 3/2=p
t is the total number of pens and pencils.
