Answer:
6^27
Step-by-step explanation:
To answer this, we are going to use one of the laws of indices
We have this as;
(a^b)^c = a^(b * c) = a^bc
we are going to apply same here
(6^-3)^-9 = 6^(-3 * -9) = 6^27
<u>Corrected Question</u>
Matt makes $80 a month mowing lawns. His friend James also mows lawns, but he makes x dollars less per month than Matt does. James makes a total of $816 per year. How much less each month does James make than Matt? Solve the linear equation to find the value for x
. Remember that x represents how much less per month James makes than Matt
Equation: 12(80 – x) = 816
Answer:
x=$12
Step-by-step explanation:
To solve the given equation
12(80 – x) = 816
First, we distribute:
960-12x=816
Collect like terms
12x=960-816
12x=144
Divide both sides by 12
x=12
Therefore, James makes $12 less than Matt every Month.
Answer:
t = 5
