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

Whats the answer two -9=-2y-1
OverLord2011 [107]
First you have to leave your y alone so you want to move the -1. Since you are moving it to the other side it will now become a +1. It will be +1-9 which will equal to -8. Now you have -8=-2y. You want to permanently leave the y alone so now you divide by 2. (-8/-2=-2y/-2) It should be 4=y. That means that 4 is your answer. Remember to make your answer a positive number because it is a negative divided by a negative!

Both tosses 50%

<span>Which of the following is closest to the probability that Ike's proportion is ringers is higher than Mike's for those tosses?
</span>
P(m) = 70/100
P(i) = 67/100
P(b) = 50/100

= P(b) * P(i) 
= 50/100 * 67/100
= 0.335
