Answer:
Factoring
Step-by-step explanation:
x^2 + 7x = x(x + 7) = 0
So
x = 0 or x = -7
I'm sorry, but the spinner that you choose does matter in this case.
For spinner A, there are 5 equal sections with a 1 being in only one of them as well. This gives you a
![\frac{1}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B5%7D%20)
chance of landing on the number 1.
For spinner B, there are 6 equal sections with a 1 being in only one of them. This gives you a
![\frac{1}{6}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B6%7D%20)
chance of landing on the number 1 - a worse chance than if you were to use spinner A.
So for this question,
you have a better chance of landing on number 1 if you choose to use spinner A.
Answer:
35
Step-by-step explanation:
20% * x = 7
20/100 * x= 7
x = 7 *100/20 (7*100÷20)
Plug in the known variables.
5n + 2 n = number of games bowled
5(3) + 2 = 15 + 2 = 17
