Answer:
5 hours
Step-by-step explanation:
First, you set the equations equal, so 20h=17h+15
Second, you isolate the h, so you would subtract 17h from both sides, giving you 3h=15
Last, you divide both sides by 3 giving you h=5, meaning the companies charge the same price after 5 hours.
I believe there are 35 backpacks in all. 2 closets have 6 shelves all together. Then 6*5=35.
Answer:
3 choices :
-There's the largest possible number of mosquitoes when rainfall is about 2 cm.
- There are no mosquitoes when there is no rainfall
- There are no mosquitoes when rainfall is about 4 cm
Step-by-step explanation:
I took the quiz.
Your answer would be 34°.
This is because a triangle adds up to 180°.
So to find the missing side we work with what we do know.
We know that one side is 50° and the other side is 96°
To find our third side add up the two sides we do know so adding 96 and 50 together will get us 146.
Then we subtract 146 from 180° because 180° adds up to a triangle.
Subtract and you get an answer of 34°.
Have a great Day!

Answer:
(x, y) = (2, -2)
Step-by-step explanation:
We would normally choose to use substitution when x or y could be easily solved-for without having fractions involved. That is not the case here. However, we observe that the term 3y appears in both equations, so we can substitute for "3y" instead of "y".
From the second equation, ...
3y = 5x -16
Substituting into the first equation, ...
2x +(5x -16) = -2
7x = 14 . . . . . . . . . add 16
x = 2 . . . . . . . . . . divide by 7
Using our equation for y, we get ...
3y = 5(2) -16 = -6
y = -2 . . . . . . . . . divide by 3
The solution is (x, y) = (2, -2).
