Question

Hallie rode her biycle 7 miles less than 3 times the number of miles Samantha rode. If Samantha rode her bicycle 23 miles, how many miles did Hallie ride?

Answer 1

Hallie ride 62 miles on bicycle.

Explanation:

Given:

Let the number of miles Samantha rode be 'x'.

Hallie rode her bicycle 7 miles less than 3 times the number of miles Samantha rode.

It means that number of miles Hallie ride is equal to 3 multiplied by number of miles Samantha rode and then subtracting by 7.

framing in equation form we get;

number of miles Hallie ride =
`3x-7`

But Given:

number of miles Samantha rode =23 miles.

Now by substituting the value of
`x=23` in above equation we get;

number of miles Hallie ride =
`3x-7 = 3*23-7 = 69-7 = 62 \ miles`

Hence Hallie ride 62 miles on bicycle.
