Answer:
His savings be $32 and spendings be $112.
Step-by-step explanation:
Let her savings and spending be 2x and 7x.
Total earning is equal to the sum of savings and spending.
ATQ,
2x+7x=144
9x=144
x = 16
Savings = 2x = 2(16) = $32
Spendings = 7x = 7(16) = $112
Hence, his savings be $32 and spendings be $112.

Answer:60
Convert the fraction 3/4 to decimal form to get 3/4 = 0.75
To factor out 3/4, we divide each term by 3/4 or 0.75
It might be easier to divide by 0.75 to avoid two division symbols
So (3/4)z+6 = 0.75z+6
Divide each term (0.75z and 6) by 0.75 which is what we want to factor out
0.75z/0.75 = z
6/0.75 = 8
Therefore,
0.75z+6 = 0.75*(z+8)
Note how we can distribute the 0.75 back through to each term inside (z and 8) and we'll end up with 0.75z+6 again.
The answer in fraction form is

which is 3/4 outside the parenthesis multiplied by the group (z+8)
