Suppose a baby weighed 8 pounds at birth and gained about 1.2 pounds each month during the first year of life to the nearest pound approximately what was the weight of the baby after the seventh month

Multiply the gain per month by the number of months:

1.2 x 7 = 8.4 pounds.

Add to the birth weight:

8 + 8.4 = 16.4 pounds.

To the nearest pound = 16 pounds.

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}
