Let x and y be the rate per hour for Mechanic 1 and 2 respectively.
Then,
x+y=205 ---------- (1)
Additionally,
10x+15y = 2500 ------ (2)
Solving equations 1 and 2;
Multiply (1) by 10 and subtract two from the result,
10x+10y = 2050
10x +15 y =2500
----------------------
-5 y = --450 => y = 450/5 = $90
Then,
x= 205-90 = $115
Therefore,
Mechanic 1 charged $115 per hour
Mechanic 2 charged $90 per hour
Answer: (You have to do a tiny bit of work, but im practically giving you the answer)
Step-by-step explanation: We’re trying to find out how many gallons of gas it takes to drive 1 mile.
1. So, 8 divided by 272= 0.02941176
2. Simplify 0.02941176 and you have your answer!
0.24/.012 Answer= 20
You just divide the .24 by .012
Answer:
2(3+7)=20 and 20 is a multiple of 4
Step-by-step explanation:
4 times 5 equals 20, which makes it a multiple of 4
3 and 7 are both odd, and added together get 10. Times that by 2 and you get 20
8p +5 = $29
The above is the equation
If you want to know how many pizza were ordered then you subtract 5 from each side of the equal sign then you would have 8p=24 then divide by 8 on both sides of equal sign . p= 3 ; so 3 pizzas were order plus a charge of $5 for delivery.
