During practice, a basketball player hits 70% of his free throws. If he missed 12 free throws, how

many free throws did he attempt during practice?

so 30% of his shots = 12

.3x = 12
x = 12/.3 = 40

he took 40 shots

check:
70% of 40 = 28
so he hit 28 , must have missed 12

WTF (wow that's fantastic)

To find out how many free throws the basketball player attempted during practice, we'll use the information given that he hits 70% of his free throws and missed 12 free throws.

Step 1: Let's assume the total number of free throws attempted is 'x'.

Step 2: We know that the player hits 70% of his free throws, which means he makes 70% of x free throws.
So, the number of made free throws is 0.70x.

Step 3: We also know that the player missed 12 free throws. Therefore, the number of missed free throws is 12.

Step 4: We can equate the made and missed free throws to find the total attempts:
Number of made free throws + Number of missed free throws = Total attempts
0.70x + 12 = x

Step 5: Simplify the equation by subtracting 0.70x from both sides:
12 = 0.30x

Step 6: Divide both sides of the equation by 0.30 to solve for x:
x = 12 / 0.30
x = 40

Therefore, the basketball player attempted 40 free throws during practice.
