Distribute. 11 x 2x is 22x. 11 x 3 is 33. So the answer is 22x +33.
Answer:
17 hours
Step-by-step explanation:
We first need to find the hourly rate:
156 / 12 = 13
Hourly Rate: $13
Now we can divide 221 by 13, this gives us 17.
That means that Frank will have to work 17 hours to make $221.
Hope this helps!
Answer:
c. x=3
Step-by-step explanation:
4^x = 8^(x − 1)
4 = 2^2
8 = 2^3
2^2^x = 2^3^(x-1)
We know that a^b^c = a^(b*c)
2^(2x) = 2^(3*(x-1))
2^(2x) = 2^(3x-3)
The bases are the same so the exponents are the same
2x = 3x-3
Subtract 3x from each side
2x-3x = 3x-3-3x
-x = -3
x =3
