"(-1, 0)" is the one ordered pair among the following choices given in the question that <span>is not a solution to the inequality y -3x - 2. The correct option among all the options that are given in the question is option "C".
"</span>(0, 4)" is the one ordered pair among the following choices given in the question that is a solution to the inequality y -3x - 2. The correct option among all the options that are given in the question is option "B".
The rate of Sue is 1 car per hour: 1 (c/h)
then the rate of Steve is 2 (c/h) , because Steve works faster, he can wash twice the number of cars, for the same amount of time.
Thus If Steve and Sue work together, they can wash 1 + 2 = 3
(cars per hour).
That is, the rate of Steve and Sue working together, is 3 (c/h).
In the first 30 minutes, Sue washes half of the car.
The remaining half will be washed at a rate of 3 (c/h)
The main formula is Work = Time * Rate
where Work is washing (1/2)c, and rate is 3(c/h)
Time=Work/Rate =
1/ 6 h =(1/6)*60 min = 10 min
Answer: 10 min
The answer is 38.6
77.2 x 0.5 = 38.6
I hope this helped :)
