Answer:
peters net income is 28,000
If the runner moves at 6 miles per hour for 2 hours before the cyclist starts, the runner has a 12 mile lead at the beginning. If the cyclist is going at 16 miles per hour, he is overtaking the runner at 10 miles per hour, because 16-6=10. Then, the amount of time it takes the cyclist to go 2 miles in 10 miles per hour is the answer. this is 1/5 of an hour, or 12 minutes.
4(2b+2)-3
8b+8-3
8b+5
the bolded is you answer
20% percent refers to the rate
So to find 20% off of $125 you have to multiply the rate by the original price and then subtract that number from the original price
First you have to make the percent into a decimal. To do that you have to move the decimal point over to the left two times or divide by 100:
20/100= .20
So the equation would be:
.20 • 125= 25
Now you have to subtract from the original number:
125-25=100
So the answer would be that the stereo would cost 100 with the 20% off sale
Answer:
1. 148
2. 17
Step-by-step explanation:
1. m<FEC + m<CED = m<FED
32 + m<CED = 180
m<CED = 180 - 32
m<CED = 148
2. m<CEA + m<AED = m<CED
(6x - 20) + (3x + 18) = 151
9x - 2 = 151
9x = 153
x = 17
