Answer:

The last one: 70/100 = x/80

And 56 free throws.

Explanation:

70% is 70 out of 100. And if the player is free throwing a total of 80 times, then 80 is 100% of the free throws. Both of the values that represent 100% are the denominators in the fractions.

\frac{70}{100} = \frac{x}{80}

The equations are equal, and whatever you do to the bottom, you have to do to the top. 100 was multiplied by 4/5 to get 80. So 70 is multiplied by 4/5 to get x.

4/5 * 70 is 56

0.25x2 -0.25x - 10.5 = 0<br><br>​
Tpy6a [65]

x=7 or x=-6

Let's solve your equation step-by-step.

0.25x2−0.25x−10.5=0

For this equation: a=0.25, b=-0.25, c=-10.5

0.25x2+−0.25x+−10.5=0

Step 1: Use quadratic formula with a=0.25, b=-0.25, c=-10.5.

x=

−b±√b2−4ac

2a

x=

−(−0.25)±√(−0.25)2−4(0.25)(−10.5)

2(0.25)

x=

0.25±√10.5625

0.5

x=7,−6
