Answer:

B - 34 years old

Step-by-step explanation:

First you have to multiply 42 times 3 to find the total age of the three people. Then multiply 40 times 4 to find the age of the four people in all. Subtract.

42 × 3 = 126

40 × 4 = 160

160 - 126 = 34

dimaraw [331]

Answer:

1 cups of cereal will be needed

2:3:5

3/2 = 1.5/x

= 2 * 1.5 = 3 * x

3x = 3

x = 3/3

x = 1
