The base is the greatest surface area
So 80% of 15 games won equal 12 games won and 3 lost. This is because 15/10 = 1.5 and 1.5 x 8 =12.
For 30, you do the exact same thing but with 90% instead. 30/10 = 3. 3 x 9 = 27.
So they need to have won 27 games to get a 90% winning percentage out of 30 games.
But since the question asks how many MORE games they need to play, it'll be 27-12 = 15.
So they need to win 15 more games to get a 90% winning percentage
X - (8 - x), if x is your number
Option D.
H = 90 + 2.50r (Henry makes a flat rate of 90 and 2.50 per repair.)
Y = 75 + 5.25s (Yolanda makes a flat rate of 75 and 5.25 per sale.)
<u><em>Answer: x=4 *The answer should be the positive sign.*</em></u>
Step-by-step explanation:
cancel by the common factor of 6.
x/16=1/4
multiply by 16 both sides of an equation.
16x/16=1*16/4
multiply the numbers.
1*16=16
=16/4
16/4=4
x=4
Hope this helps!
Thanks!
Have a great day!
