Answer:
There is a loss of 2 yards.
Step-by-step explanation:
To find the overall gain or loss, we add or subtract there values.
Initially, we have 0 yards.
Records 14, so 0 + 14 = 14, that is, for now a gain of 14
Then loses 7, so 14 - 7 = 7, for now a gain of 7.
Then, 7 - 9 = - 2, so in all, there is a loss of 2 yards.
let mother's age y and daughter age x
a/q y=3x and y-5=5x-25
put y in second eq we get x=10 &y=30(their present age)
there are 7 days in a week x 0.10 cents saved each day on the week = 0.70 cents every week
88.
428-360 = 88
