Initially a pool contains 340 gallons of water. a hose is placed in the pool, and the water is turned on. the hose adds 5.2 gallons of water per minute. write an equation to represent the total amount v of water in the pool in terms of x, the number of minutes the hose has been on. a. v = 5.2x + 340 c. v = -5.2x + 340 b. v = 5.2x d. v = 340x + 5.2

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

step-by-step explanation:

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
