Boys:girls = 4/5
boys = 4/(4+5) = 4/9 of the class
<h3>
Answer:</h3>
C) y = 6x
<h3>
Step-by-step explanation:</h3>
Pick any point. It is often convenient to use x = 1 (no marked point) or x = 10 (where y = 60).
Use these values to see which equation agrees.
A: 60 ≠ (1/6)·10
B: 60 ≠ 2·20
C: 60 = 6·10
D: 60 ≠ 12·10
____
Or, you can solve ...
... y = kx
for k, using the point values you found on the graph.
... 60 = k·10
... 60/10 = k = 6 . . . . . divide by 10
This makes the equation be ...
... y = 6x . . . . . . matches selection C
Answer:y=5(6)^x

Answer:
Step-by-step explanation:
Adam plans to choose a video game from a section of the store where everything is 75% off.
The expression written by him for this situation is d - 0.75d.
Here, the part d represents the sale price before discount and the part 0.75d is the discount amount.
The expression written by Rena is 0.25d.
Here, the part 0.25d is the price after discount. Since 75% is the discount, the rate after disount is 25% and 25% of d is 0.25d.
Answer
x=-12
Explanation
Move the terms
-17-2x=7
Add the numbers
-2x=24
Divide both sides of the equation by -2
x=-12
Hope this helps:)
