Answer:
13.5
Step-by-step explanation:
Basically you need to make the denominator (whats on the bottom) the same, lets take the first one for example
2 3/4, lets put this all over 4 for the same denominator.
2=8/4, and then add this to 3/4 to get 11/4.
the second part will work the same way,
start by making 1 into 8/8. add this to 1/8 to get 9/8
now we have to add 11/4 and 9/8. to do this, you have to find the smallest multiple between the two (for example: between 6 and 4 it would be 12, since 4*3= 12, and 2*6=12)
now, the smallest common multiple between 4 and 8 would just be 8
11/4= 22/8, since you multiply the bottom and top by the same amount so it still equals 11/4, but your denominator will now be 8.
now you can subtract. 22/8- 9/8= 13/8
final answer: 13/8
try the rest yourself since this is important for later math, hoped this helped :)
Answer:
The answer is 206.8. But you want me to round to the nearest cent so the real answer is $207.00

Answer:
Step-by-step explanation:
You could factor the trinomial and solve it that way, but that is the long way. Just put a - 4 wherever you see an x.
x^2 + 3x + 2 =
(-4)^2 + 3(-4) + 2
16 - 12 + 2
6
The answer is 6.
