Answer:
8 hours
Step-by-step explanation:
You can solve this problem by inputting the values into an equation. Here is the equation below:
Lets solve for x. First you subtract 50 from 130.
1) 
2) 
Next, you divide 80 by 8 to get x by itself.
1) 
2) 
This means that you must mow lawns for 8 more hours to get a total of $130 in your bank account.
x = 2, that is B(2) = - 1
From the coordinate diagram, the value of x ( x- axis ) corresponding to the value of y = -1 ( y- axis ) is x = 2
That is the point (2, - 1 )
Hey i can’t see the picture, it’s too pixelated and like has lines all over it, maybe post it again if love to help :)
Answer:
x = 20
y = 7.2
Step-by-step explanation:
12/x = 9/15
9x = 180
x = 20
12/x= y/12
12/20 = y/12
144 = 20y
y = 7.2
y = 20
