Answer:

\large\boxed{x=\dfrac{27}{2}\to x=13\dfrac{1}{2}\to x=13.5}

Step-by-step explanation:

\dfrac{2}{3}x-2=7\qquad\text{add 2 to both sides}\\\\\dfrac{2}{3}x-2+2=7+2\\\\\dfrac{2}{3}x=9\qquad\text{multiply both sides by 3}\\\\3\!\!\!\!\diagup^1\cdot\dfrac{2}{3\!\!\!\!\diagup_1}x=3\cdot9\\\\2x=27\qquad\text{divide both sides by 2}\\\\\dfrac{2x}{2}=\dfrac{27}{2}\\\\x=\dfrac{27}{2}\to x=13\dfrac{1}{2}\to x=13.5

Alexandra [31]

Answer:

102.6666... feet in one second 1232 feet in twelve seconds.

Step-by-step explanation:

Most clear way of solving this breakdown the proportions by keep the value.

1 mile = 5280 feet.

1 hour = 60 minutes = 3600 seconds -- See now it is easy.

Feet per second...

                =  feet/seconds

(70*5280) = 369,600/3,600 = 102.666666667 -- That is 102.66...feet per second.

For twelve seconds just multiply by 12.

102.666666667*12 = 1232 feet in twelve seconds.
