A basketball player makes 75% of her free throws. If she made 84 free throws this season, how many has she attempted?
myrzilka [38]
If you would like to know how many free throws did a basketball player attempted, you can calculate this using the following steps:

75% of x is 84
75% * x = 84
75/100 * x = 84
x = 84 * 100 / 75
x = 112 free throws

The correct result would be 1<span>12 free throws.</span>

At Fruits R Us, Mr. Orchard realizes that dried pineapple slices and dried apricots were two of his top dried fruit sellers. So
Rudik [331]

Answer:

Step-by-step explanation:

From the information given, you can write the following equations:

x+y=300 (1)

5x+8y=300*7

5x+8y=2100(2)

First, you can isolate x in (1):

x=300-y (3)

Now, you can replace (3) in (2):

5(300-y)+8y=2100

1500-5y+8y=2100

3y=2100-1500

y=600/3

y=200

Then, you can replace the value of y in (3) to find x:

x=300-200

x=100

According to this, the answer is that he should use 100 pounds of dried pineapple and 200 pounds of dried apricots.
