Answer:
9 1/3
Step-by-step explanation:
1. Make 4 2/3 into a improper fraction
4 2/3= 14/3
2. Keep, change, flip
14/3 x 2/1
3. Multiply
14/3 x 2/1= 28/3
4. Simplify
28/3= 9 1/3
(btw keep, change, flip basically means to keep the first fraction the way it is, change the division sign to a multiplication sign, then flip the second fraction so the original denominator is the new numerator, and vise versa.)
Answer:
f(3) = 16
Step-by-step explanation:
f(x)= 7x-5
We want to find the value when x=3
f(3) = 7*3 -5
f(3) = 21-5
f(3) = 16
Answer:
368 milliliters.
Step-by-step explanation:
Compound A + Compound B = 1 drug
4 + 7 = 1 drug
11 milliliters = 1 drug, so 1012 milliliters = 92 drugs
Multiply the compounds by the amount of drugs, e.g.
4 x 92 = 368 ( Compound A )
7 x 92 = 644 ( Compound B )
368 + 644 = 1012
368 milliliters of Compound A are needed to make 1012 milliliters of the drug.
Hope this helps :)
Answer:
7x-17y
Step-by-step explanation:
We need to find the expression which represents the difference when (-2x+10y) is subtracted from (5x−7y) . Let the result is R.
So,
R = (5x−7y)-(-2x+10y)
Solving brackets as follows :
R = (5x−7y)+2x-10y
taking like terms together
R = (5x+2x)+(-7y-10y)
R = 7x-17y
Hence, when (-2x+10y) is subtracted from (5x−7y) the result is (7x-17y).
