Question

Tim is 35 years old. He is 7 years younger than 6 times his daughter's age. The equation,
6x - 7 = 35, where x equals his daughter's age, can be used to find the age of Tim's daughter. How
old is Tim's daughter?
Choose the correct answer below.
OA. 7 years old
OB. 9 years old
OC. 4 years old
OD. 8 years old

Answer 1

Answer:

A. 7 years old

Step-by-step explanation:

6x-7=35 is the equation.

Add 7 to both sides, which gives you 6x=42.

Then both sides by 6, so 6/6=x and 42/6=7

So, x=7.

Since x is his daughter's age, x=7, so his daughter is 7.

Answer 2

6x-7≈35

or,6x=35+7

or,6x≈42

or,x=42÷6

x≈7
