Answer:
2(5)+5(0)=10
Step-by-step explanation:
There are several ways for this equation to work but a very simple way is shown below.
2*510+5*0=10
10+0=10
10=10
A percentage can just be written as a decimal where 100% = 1.00
15% = 0.15
75.5 * 0.15 = 11.325
You just multiply.
-5/12 would be the answer
The value of a would be 4.2, because the negatives cancel out each other.
Answer:
Kevin will earn the money before than Philip
Philip needs at least 4 weeks
Kevin needs at least 3 weeks
Step-by-step explanation:
Let's call x to the number of weeks
Philip works 6 hours each weekend, which means 6 hours per week, earning $8.75 per hour, which is equivalent to 6*8.75 = $52.5 per week
Philip has already saved $45. Then he needs the next number of weeks:
52.5*x + 45 = 225
x = (225 - 45)/52.5
x = 3.4
Philip needs at least 4 weeks
Kevin works 3 hours per day for 3 days a week, which means 9 hours per week, earning $7.5 per hour, which is equivalent to 9*7.5 = $67.5 per week
Kevin has already saved $30. Then he needs the next number of weeks:
67.5*x + 30 = 225
x = (225 - 30)/67.5
x = 2.9
Kevin needs at least 3 weeks
