total of 18 apples and bananas altogether. By following the steps below, determine the
number of apples, 2, and the number of bananas, y, that Jocelyn bought.
Determine three ways to have a total of 18 apples and bananas:

answer: t=3

step-by-step explanation:

susie has 7 apples

b and c

step-by-step explanation:

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}
