Jack was paid $7200 for mowing the grass in 12 acre field. How much will he be paid at the same rate for mowing 7.5 acre field? Write an equation with 7.5 as x to represent this problem.

investment b is an ordinary annuity with $3,909.64 in the account after one year.

step-by-step explanation:

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
