You would divide 198 by 9.
198÷9=22
Each person would clean 22 rooms.
This could be wrong because I'm going into the fifth grade but wouldn't it just be (7,-3)?
Answer:
224
Step-by-step explanation:
Number of trains in the roller coaster = 2
Number cars in each train = 7
Total number of cars = Number of trains
Number of cars in each train =
= 14
Number of people in each car = 16
Total number of people in 14 cars = Number of people in one car
Number of cars = 16
14 = 224
i.e.
Total number of people in the roller coaster in one run = 224
Number of runs made by each train in one hour = 10
Therefore, Total number of people that can ride the roller coaster in one hour can be found by multiplying the number of runs with total number of people in the roller coaster in one run.
224
10 = <em>2240</em>
Distribute the 2 to get the pink box
10x + 2y = 18
Then if we are subtracting the bottom equation from the pink box
10x + 2y = 18
-(10x -7y = -18)
9y = 36
y = 4
