Answer:
he makes 14 field goals and 7 extra point kicks
Step-by-step explanation:
- f=#of field goals
- e=extra kick points
- f+e=21
- 3f+1e=49
- subtract top from bottom
- 2f=28
- f=14

Answer:
≈ 25 in²
Step-by-step explanation:
The general formula for the area of a circle is:
A=πr²
A = (3.14)(8²)
Since the size of the pizza is 16 inches across, the radius is half of that, or 16÷2 = 8 inches.
A ≈ 201 in²
Since there 8 slices of pizza, you can take the total area and divide by 8:
201 ÷ 8 ≈ 25 in²
Answer:
r = -4
Step-by-step explanation:
If M is the midpoint of DE, that would mean that the distance from M to D and M to E would be the same.
This creates the equation 1-8r=13-5r.
Now it's just simple algebra.
You add 8r to both sides, creating 1=13+3r. Then, you subtract 13 from both sides, getting 3r=-12. Dividing both sides by 3 and solving for r, you get r=-4.
Checking our answer, you see that 1-8(-4)=1-(-32)=1+32=33, and 13-5(-4)=13-(-20)=13+20=33.
To write an equation you need a slop and y intercept. To find the slop use the formula y2-y1 /x2-x1. and for the y intercept use the formula y=mx+b
