Answer:15.5 because you have to take away some point
Step-by-step explanation:
Distribute the 5 to the (2+y). Parenthisis always come first. after that combine the 5y and the -y. you should end up with 2-(+4y) +2. add the -2 and +2. you should be left with 4y
Answer:
B. the store gets a new 40-pound dog
Step-by-step explanation:
1) 4(x+7)=80
Value of x
Multiply
4x+28=80
4x=80-28
4x=52
X=52/4
X=13
The greatest common factor of these three numbers is 4.
In order to find this, we start with factors of the smallest number (12). The factors are listed below.
12, 6, 4, 3, 2, 1
Now we start with the biggest and work our way down until we find something that goes into all 3.
12 does not go in evenly to either 44 or 28, so we can't use that.
6 does not go in evenly to either 44 or 28, so we can't use that.
4 goes in evenly to both as seen below:
44/4 = 11
28/4 = 7
Therefore, 4 is the greatest common factor.
