Let's solve for x:
100x=1000
Divide by 100
x=10
You should expect to win 10 times.
Answer:
x=17
The angles are Vertical.
Step-by-step explanation:
6x17 equals 102. Then subtract 12 from 102 to get 90 degrees.
6(17)-12=90 degrees
N*(21/100)=(700/100)
n=(700/100)/(21/100)
n=(700/100)*(100/21)
n=700/21
n=33+1/3
So <em><u>thirty three</u></em> $0.21 pencils can be purchased for $7.00.
