3x + 2y + y - 3x = 180
3y = 180
y = 180/3
y = 60
3x = y - 3x
Let y = 60
3x = 60 - 3x
3x + 3x = 60
6x = 60
x = 60/6
x = 10
Answer: x = 10, y = 60
Kim drives = x
Terry drives = 2x
Jerry drives = 6x
Let us go through our answer choices and choose one.
A is incorrect because we are not being asked to add anything.
B is incorrect because it equals what all of the drivers drive.
2(x+3)
2*x + 2*3
2x + 6x
C is incorrect because we are not being asked to subtract.
D is correct because Jerry drives 3 times as much as terry.
2x*3
6x
So our final answer is D. 6x
Answer: x=16
Step-by-step explanation:
For this problem, we can set a proportion to find the side length of the smaller rectangle.
[cross multiply]
[divide both sides by 15]
x=16
