Question

The product of the ages of two adults is 770. What is the sum of their ages?

Answer 1

Answer:

57

Step-by-step explanation:

the factors of 770 are  1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

so we should choose the factor of 770 which is above 18 and below 40 because the question says we should find and the sum of the ages of the adults. We should leave the factors under 18 and above 40.

so the factors are 22 and 35. 22+35 will give 57

                                    22

                                  x 35

                                  770
