Answer:
44
Step-by-step explanation:
ΔTRS ≅ ΔTRQ
TS = TQ
2x + 8 = 40
x = 16
The same situation
SV = QV
3 * 16 - 4 = 44
62.5%
What I did was divided 43.75 by 70 to get 0.625.
Then I moved the decimal over two places to the right to get 62.5.
Answer:
85 girls and 140 boys
Step-by-step explanation:
We are given two points: (4, -8) and (8, 5)
General equation of a line: y = mx + c
First find m (the gradient). There is a formula for this: (change in y)/(change in x) = gradient
(5 - -8) / (8 - 4) = (13) / (4) = 3.25 = m
y = 3.25x + c
Now we need to find c (the y-intercept; the value of y when x=0).
Substitute in any one of the coordinates - let's use (8, 5)
(5) = 3.25(8) + c
(5) = 26 + c
c = -21
The equation of the line: y = 3.25x - 21
I think that this answer is correct - sorry if it seems rushed.
Hope this answer helps :)
Answer:
equation
Y being the total cost
50 being the one time rental fee
Y= 50+0.5x
