Answer:

8(3) + 10(7) = 94

8b + 10l = y

Step-by-step explanation:

First, lets make an equation to solve for the numbers.

8b + 10l = Total Amount of Money (y)

Plug in the values.

8(3) + 10(7) = 94 is the amount of money he gets if he does 3 hours of babysitting and 7 hours of lifeguarding.

Answer:

120 degrees

Step-by-step explanation:

Attached is a screenshot.

y = 180 - 50 - 70 = 60.

x + y = 180, so x = 120

Answer:

$y=-\frac{1}{4}x+2$

Step-by-step explanation:

Hi there!

What we need to know:

Linear equations are typically organized in slope-intercept form: $y=mx+b$ where m is the slope and b is the y-intercept (the value of y when x is 0)
Parallel lines always have the same slope

1) Determine the slope of line S using line R (m)

$y=-\frac{1}{4} x+3$

We can identify clearly that the slope of the line is $-\frac{1}{4}$ , as it is in the place of m. Because parallel lines always have the same slope, the slope of line S would also be $-\frac{1}{4}$ . Plug this into $y=mx+b$ :
