I think for number 3, it is the third option.
2+2 is 4 LOL you just gotta add 1+1+1+1
If Angel ran a full lap in two minutes, then she ran half of a lap in one minute. If a lap is 2/5 kilometers, the half a lap is 1/5 kilometers.
The first thing you should do in this case is to write the expression correctly:
- (1/9) y + (1/3)
Now, we take out common factor (1/9) obtaining:
1/9 (-y + 3)
Let's check:
1/9 (-y + 3)
-1/9y + 3/9
-1/9y + 1/3
OK
Answer:
An expression equivalent is:
1/9 (-y + 3)
Your answer is 3 raised to 4 that is 3^4.
Hope this helps :)
