21
Step-by-step explanation:
Add all the numbers together
6+8+2.5+2.5+2=21
Step-by-step explanation:
1. 1/4(x + 12)=2 - first isolate X'
- 12 -12
2. 1/4(x) = -10 - 1/4 since its a fraction, you'll have to subtract not divide
-1/4 - 1/4
3. x = -10.25
Andre did the first step correctly, but on the second step he just divided 1.4 by -10, instead of subtract 1/4 from both sides.
Fractions,rats, and percents all interconnect. For ext,50%=11/2 =1:2
