Answer:
VW = 3
Step-by-step explanation:
From the diagram, we know that UW = 11.
We also know that UV + VW = UW, because UW is the length of the whole segment.
Using substitution (knowing 2 of the line segments), we find that 8 + VW = 11.
If we subtract 8 from both sides using inverse operations, we find that VW = 3, which is the answer.
Hope this helps!
Answer:
x = 5/2 = 2.5
Step-by-step explanation:
Given
f(x) = 3x-7
g(x) = x+2
g^(-1)(x) = f(x)
First find g^(-1)(x) = h(x)
x=h(x)+2
h(x) = x -2
h(x) = x - 2 = f(x) = 3x-7
solve for x
x-2 = 3x -7
-2 + 7 = 3x - x
2x = 5
x = 5/2
Answer:
michelle, kaley, and Rebecca.
Step-by-step explanation:
They have sold 100 tickets so far ($75), they need to sell 380 ($285) tickets in total and need to sell 280 more tickets.
Michelle was wrong because she should have divided 210 (how much more money they need to sell on tickets) into .75 (which is how much each ticket costs).
Kaley was wrong because she should have also divided 210 into .75 like Michelle.
Rebecca should have also divided 210 into .75.
Eva was the only correct one.
