Step-by-step explanation:
To add or subtract 2 fractions, they must have same denominators, if they not do that
- Find the Lowest common multiple of the two denominators (LCM)
- Replace each denominator by it
- Divide The LCM by each denominator and multiply the numerator of each fraction by its quotient
∵ ( x +
) + (
x -
)
- Let us start with adding the like terms
∴ ( x +
) + (
x -
) = (
∵ ( x +
x ) have same denominators, then we can add them
∴ ( x +
x ) =
x
∵ ( -
) do not have the same denominators, then we must find
LCM of 8 and 4
- The LCM of 8 and 4 is 8 because 8 is the first common multiple
of 8 and 4
∵ LCM of 8 and 4 is 8
- Divide 8 by the denominator 4
∵ 8 ÷ 4 = 2
- Multiply the numerator of the fraction by 2
∴
∴ ( -
) = (
-
) =
∴ ( x +
) + (
x -
) =
x +
The sum of ( x +
) + (
x -
) is

Answer: C) (1,0.80) represents the unit rate. E) (25,20) represents the price of a necklace with 25 beads
Step-by-step explanation:
(1, 0.80) represents the unit rate.
(25, 20) represents the price of a necklace with 25 beads.
= unit rate →
= 0.80;
= 0.80;
= 0.80
Point (1, r) → (1, 0.80) represents the unit rate.
25(0.80) = 20; thus, (25, 20) represents the price of 25 beads.
Hope this helps
