Question

Using substitution which number from the set { 15, 25, 35, 55, makes the equation y 15 = 40 true
25
55
15
35

Answer 1

Using substitution, we can replace the variable y with each number from the set { 15, 25, 35, 55 } and see which equation makes the equation "y * 15 = 40" true.

If we substitute y = 15:
15 * 15 = 225, which is not equal to 40.

If we substitute y = 25:
25 * 15 = 375, which is not equal to 40.

If we substitute y = 35:
35 * 15 = 525, which is not equal to 40.

If we substitute y = 55:
55 * 15 = 825, which is not equal to 40.

Therefore, none of the numbers from the set { 15, 25, 35, 55 } make the equation true.
