Use these variables to make an equation-
y is the total amount.
$50 is where you start charging(y intercept, variable b).
x is how many visits Marsha made.
The equation can be in slope-intercept form (y=mx+b)-
$144=$2x+50
Solve for x using inverse operations.
Subtract 50 from both sides-
144-50=2x+50-50
94=2x
Divide 2 from both sides-
94/2=2/2
x=47
Marsha made 47 visits to the health club.
Answer:
angle 1 = 20; angle 2 = 160
Step-by-step explanation:
(x-12) + 5x = 180
6x-12 = 180 (add 12 to each side)
6x = 192 (divide each side by 6 to get x by itself)
x = 32
plug x into each equation
angle 1: 32-12=20; 20
angle 2: 32x5= 160; 160
They traveled 416.25 miles
we now that they travel 55.5 in one hour and we know they traveled 7.5 hours, so multiply 7.5*55.5
which gives you 415.25 miles
