Question 1

Select the statement that is true for solving the equation 10x = 90(1 point)
Responses

Multiply both sides by 10; x = 900.
Multiply both sides by 10; x = 900.

Multiply both sides by 10; x = 9
Multiply both sides by 10; x = 9

Divide both sides by 10; x = 9.
Divide both sides by 10; x = 9.

Divide both sides by 10; x = 900.
Divide both sides by 10; x = 900.
Question 2
Which statement is true to solve for x in the equation 14x = 56?(1 point)
Responses

Divide both sides by 14; x = 4
Divide both sides by 14; x = 4

Multiply both sides by 14; x = 784
Multiply both sides by 14; x = 784

Multiply both sides by 14; x = 4
Multiply both sides by 14; x = 4

Divide both sides by 14; x = 784
Divide both sides by 14; x = 784
Question 3
Select the statement that is true for solving the equation x/13 = 39(1 point)
Responses

Divide both sides by 13; x = 507
Divide both sides by 13; x = 507

Divide both sides by 13; x = 3
Divide both sides by 13; x = 3

Multiply both sides by 13; x = 507
Multiply both sides by 13; x = 507

Multiply both sides by 13; x = 3

1 answer

Here are the correct answers for each question based on solving the equations:

Question 1: The correct statement is:

  • Divide both sides by 10; x = 9.
    (10x = 90, divide both sides by 10: x = 90/10 → x = 9)

Question 2: The correct statement is:

  • Divide both sides by 14; x = 4.
    (14x = 56, divide both sides by 14: x = 56/14 → x = 4)

Question 3: The correct statement is:

  • Multiply both sides by 13; x = 507.
    (x/13 = 39, multiply both sides by 13: x = 39 * 13 → x = 507)

So, the respective correct choices for each question are:

  • Question 1: Divide both sides by 10; x = 9.
  • Question 2: Divide both sides by 14; x = 4.
  • Question 3: Multiply both sides by 13; x = 507.
