Answer:
8f-16g
Step-by-step explanation:
We have to simplify each term. So f becomes 8f. Then 4 times 4 becomes 16
12.75 pounds, you have to multiply 8.5 x 1.5
60% of what equals 27? This is the question. "Of" always means multiply.
So... convert the percent to a decimal: .6x=27.
Divide: x=27/.6
x=45
Plug it back in to check: .6(45)=27
27=27.
Or: 27/45=.6
.6=.6
Add 2 to both sdies
now if we can facor, then if
xy=0 then x and/or y=0
note:xy=x times y and x(y) =x times y
x^2+3x+2=0
what 2 number multiply to get 2 and add to get 3
the numbers are 2 and 1
(x+2)(x+1)=0
set them to zero
x+2=0
subtract 2
x=-2
x+1=0
subtract 1
x=-1
x could be -1 or -2
x=-2, or -1
