Question

Andrew ran 5 miles less than two times the number of miles Bernadette ran. Andrew ran a total of 13 miles. Write an equation to determine how many miles Bernadette ran.

13 = 2x − 5
x − 5 = 2(13)
x/13 = 2(5)
13 + 2x = 5

Answer 1

a) 13 = 2x - 5

Explanation:

Given that,

→ Andrew ran 5 miles less than 2 times the no. of miles Bernadette ran.

→ Andrew ran a total of 13 miles.

Then the equation will be,

→ 13 = 2 times - 5

→ 13 = 2x - 5

Hence, option (a) is correct.
