You have the ratios set up but you need to cross multiply everything:
(5x + 10) x 11 = 121 x 10
55x + 110 = 1210
Subtract 110 from both sides:
55x = 1100
Divide both sides by 55:
X = 1100 / 55
X = 20

<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:
a=54
Step-by-step explanation:
Because the problem gives you the value of b simply plug it in the equation a=12b. The new equation should look like this when plugged in: a=12(4.5). Now multiply 12*4.5=54. The new equation would then become a=54
