How do i solve for x by using natural log (in)?

Unfortunately you cannot use logs to solve this.

However, it shouldn't take too long to use guess-and-check to see that

Showing that x = 2 is the solution to the equation.

You can use a graphing calculator to graph out  and  . The two curves cross at (2,13). The x coordinate of that intersection is what we're after. GeoGebra and Desmos are two free options you can pick from in terms of a graphing calculator.

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.
