Answer:
7
Step-by-step explanation:
Use secant-tangent product theorem.
1. Set up the equation
(x-3)(x-3+5) = (x-1)²
2. Solve
(x-3)(x+2) = (x²-2x+1)
(x²-x-6) = (x²-2x+1)
3. Solve for x
Subtract x² from both sides
-x-6 = -2x+1
Add 2x and 6 to both sides
x = 7
Answer:
60 points in 5 games
Step-by-step explanation:
plug the numbers of points scored into the top boxes, so the boxes should look like ( [8]+[11]+[12]+[16]+[n] ) then plug in the number of games he played in the bottom box [5] so 8+11+12+16+n all divided by 5 has to = 12
5x12 = 60
n= 60-8-11-12-16 n= 13
4,900 x 0.0725 =355.25
So,
775+355.25= $1 130.30
So she made $1 130.30!
