Question

The sum of 1 and 7 times a number is 64. Write and solve an equation to determine the number. Select the solution and graph that represents the number.

Question 1 options:

x = 4

Number line graph of x equals 4.

x = 6

Number line graph of x equals 6.

x = 7

Number line graph of x equals 7.

x = 9

Number line graph of x equals 9.

Answer 1

To solve this problem, we can set up the equation 1 + 7x = 64, where x is the number. Solving for x:

1 + 7x = 64
7x = 63
x = 9

Therefore, the number is 9. The solution is x = 9 and the corresponding graph is the number line graph of x equals 9.
