Question

The total rainfall for two days was 14.6 mm. The first day's total was 4.5 mm less than the second

day's. How much rain fell on each day in cm?​

Answer 1

first day = 5.05mm = 0.505cm

second day = 9.55mm = 0.955cm

Explanation:

Let x represent first day

Let y represent second day

x + y = 14.6

x = y - 4.5

(y - 4.5) + y = 14.6

2y - 4.5 = 14.6

2y = 14.6 + 4.5

2y = 19.1

Divide both sides by coefficient of y which is 2

y = 9.55

Substituting value of y in the equation x + y = 14.6

x + 9.55 = 14.6

x = 14.6 - 9.55

x = 5.05

To convert the values in mm to cm you divide them by 10 since 1cm=10mm
