Answer:

1.5y - 5

Step-by-step explanation:

I used the distributive approach and distributed -1/2 to the -3y and 10.

Ahmad run 5 kilometres. If he completed 15% of the race. How many kilometres is the race?

stepladder [879]

Answer:

x = 33.33 kilometers

Step-by-step explanation:

you could make use of the percent, base, and rate formula here. we know that 15% is the rate, 5 kilometers is the percent, therefore what we are looking for is our base.

$\frac{percent}{base} =\frac{rate}{100}$

$\frac{5}{x}=\frac{15}{100}$ ; cross multiply.

15x = 500

x = 33.33 kilometers

therefore, the race is 33.33 kilometers.
