Answer
x= 12
Step-by-step explanation:
alternate angles right?
9x + 23 = 11x - 1
24 = 2x
x = 12
so the angle is
(11 × 12) -1
132-1
131°
All you need are these signs, < and >
< is less than
> is greater than
so for example x<y
x is less than y
Let's assume that Susan's graph is linear. Then, we can do linear interpolation. Let y be the amount charged for 10 hours of work done:
(7-10)/(7-11) = (168-y)/(168-264)
y = $240
For Jim's Lawn care, let's find the constant slope using points (1,20) and (2,40):
m = (20 - 40)/(1-2) = 20
Then, since the y-intercept is zero, the linear equation is:
y = 20x
Substituting x = 10 hours,
y = 20(10) = $200
The difference between the two would then be:
Difference = $240 - $200 = $40
