Question

Brandy drove three times as far as Trisha. Together, they drove 48 miles. Which equation below can be used to find the number of miles Trisha drove?

A. 3x = 48
B. x = 48
C. 3x + x = 48
D. 3x2n = 48




stands for an exponent "2n"

Answer 1

Let Trisha drove x mi

Brandy drove 3×x=3x mi

Together they drove=48

Now

The equation is

• 3x+x=48
• 4x=48
• x=12

The option C can be used

Answer 2

`\textsf {C. 3x + x = 48}`

Explanation:

`\textsf {Let :}`

`\textsf {Distance travelled by Trisha = x}`

`\textsf {Distance travelled by Brandy = 3x}`

`\textsf {It mentions the sum is 48. So both distances need to be added.}`

`\implies \mathsf {3x + x = 48}`

Option C gives the right answer.
