Answer:
Judy = $5/hr
Ben = $4/hr
Step-by-step explanation:
Judy's hours at work - x
Ben's hours at work - y
8x + 10y = 80
9x + 5y = 65
Given these two equations above, we get:
10y = 80 - 8x, which means y = 8 - 0.8x.
Substitute y in the second equation with 8 - 0.8x, so we have:
9x + 5 (8 - 0.8x) = 65
9x + 40 - 4x = 65
5x = 25
x = 5
Come back to the first equation, substitute x:
8*5 + 10y = 80
10y = 80 - 40
y = 4
Answer:
56.5

Answer:
the answer is 85° because all angles in a triangle add up to 180
so u add them both up, subtract from 180 n u get 85
Answer:
See answer above.
Step-by-step explanation:
These are the ordered pairs on the graph: (-2, 5), (2, 3), (-3, -2), (0, -5), (3, -6)
The domain is the first point in teach ordered pair and the range is the second number in the ordered pair.
So the domain is {-2, 2 , -3, 0, 3}
Range is {5, 3, -2, -5, -6}
