Use substitution to determine which number from the set {6,7,8, 9} makes the equation 7c = 56 true. Show Your Work
Given equation: 7c = 56
Let's substitute each number from the set {6, 7, 8, 9} for c to determine which one makes the equation true.
1. Substitute c = 6:
7(6) = 42 (not equal to 56)
2. Substitute c = 7:
7(7) = 49 (not equal to 56)
3. Substitute c = 8:
7(8) = 56 (equal to 56)
4. Substitute c = 9:
7(9) = 63 (not equal to 56)
Therefore, the number from the set {6, 7, 8, 9} that makes the equation true is c = 8.
