Answer:
44/3 or 14 and 2/3
Step-by-step explanation:
First convert 2 and 3/4 in a improper fraction which gives you 11/4.
Next, you divide 11/4 and 3/16.
It will give you 44/3 which can be 14 and 2/3.
The answer is 45 because 45-15=30, therefore x=45.
Answer:
x = 9.17 (nearest hundredth)
The variable x is the amount the student needs to save each month in addition to his usual saved amount of $20.
Step-by-step explanation:
350 = 12(x + 20)
Multiply out brackets: 350 = 12x + 240
Subtract 240 from both sides: 110 = 12x
Divide both sides by 12: 9 1/6 = x
x = 9.17 (nearest hundredth)
The variable x is the amount the student needs to save each month in addition to his usual saved amount of $20.
If n = number of hours and the equation is 174 + 58n then the answer is 3 hours
