Answer:
17.5
Step-by-step explanation:
350×2.5×1/100
17.5/2
8.75
A is the answer because divide 74.5 by 10 and get 7.45 then 7.45 times the X or number of boxes gets you the Y or the cost of the boxes.
Answer:
Sue played 30 games
Step-by-step explanation:
Probability is typically given as a fraction or percentage where the numerator is the number of desired outcomes and the denominator is the total number of outcomes. Since Sue's won 12 games and estimated the probability to be 0.4 or 4/10, you can set up a proportion, or equivalent ratios, to solve for the number of games she played:

Cross multiply: 4x = 120
Divide by 4: 4x/4 = 120/4
Solve for 'x': x = 30 games
Answer:
(-3,3)
Step-by-step explanation:
Using elimination:
Multiply the first equation by 8 and the second by 5 which equals
40x+56y=48
-40-60y=-60
Now you add them together
40x+(-40x)=0 so that crosses out
56y+(-60y)= -4y
48+(-60)=-12
You now have -4y=-12
Divide by -4
y=3
Now plug in y to any of the equations
5x+7(3)=6
5x+21=6
Subtract 21 from both sides
5x=-15
Divide by 5
x=-3
Your final solution is (-3,3)
