Answer:

240 miles/8 minutes and 35 km/5 minutes

Step-by-step explanation:

Any certain amount or quantity of one thing which is considered in relation to a unit of another (related) thing is said to be the rate.

Also, rate is the ratio of two different quantities.

Here in the given quantities, 240 miles/8 minutes and 35 km/5 minutes are not the rates since the values in their denominators are not unit quantities.

Which equations have the same value as 3/5 (30x-15)=72 select 3

const2013 [10]

Answer:

x=4.5

Step-by-step explanation:

Given the equation $\frac{3}{5}(30x-15)=72$ , we simplify as:

$\frac{3}{5}(30x-15)=72\\\\18x-9=72$

#We further simplify as multiples of 9(divide by 9 to solve for x):

$18x-9=72\\\\2x-1=8\\\\2x=9\\\\x=4.5$

Hence, from our simplification the equation has the same value as x=4.5
