Answer:
6x
Step-by-step explanation:
I'm pretty sure
1.) -8 + 10(6 + 4r)
First multiply the 10 into (6 + 4r)
-8 + 60 + 40r
52 + 40r
2.) (8m² - 8m + 8) - (2m - 7m² - 6)
Distribute the - into (2m - 7m² - 6)
8m² - 8m + 8 - 2m + 7m² + 6
Combine like terms
15m² - 10m + 14
(idk if you need to factor this or if you can leave it as is)
Distribute 2y to both 3y and 17
• 6y+34= 12
then you subtract 34 on both sides and get:
• 6y=-22
Finally you divide 6y on both sides and end up with:
y= -11/3 as a fraction
Hope this helped!
It's %73.3. Just divide the top numerator to the denominator
Answer:
500 students in the school
Step-by-step explanation:
100 - 68% = 32%
boys percentage 68%
girls percentage 32%
difference 68 - 32 = 36% = 180
36 ÷ 18 = 2 × 50 = 100
180 ÷ 18 = 10 × 50 = 500
