Answer:
you have to convert them to equivalent units (the same denominators)
Step-by-step explanation:
first, multiply 2 and 7 by 4.
now you have 8/21.
then, make the other fraction the same value.
multiply 1 and 4 by 7.
7/21.
now your equation is 7/21 + 8/21= 15/21.

Answer:
multiply the number in each can by the number of cans and add the extras
Step-by-step explanation:
You can add them all up. This is the total of the number in each can and the extras:
8 +8 +8 +8 +8 +8 +8 +8 +8 +8 +8 +8 +8 +8 +8 +7
Or you can take advantage of the invention of multiplication to simplify repeated addition. Multiply the number in each can by the number of cans, then add the extras.
15×8 +7 = 127
x + y = 3
- x - x
y = -x + 3
y - y₁ = m(x - x₁)
y - (-1) = -1[x - (-1)]
y + 1 = -1(x + 1)
y + 1 = -1(x) - 1(1)
y + 1 = -x - 1
- 1 - 1
y = -x - 2
The answer is B.
Yupz u b right cuz 8+9 is ur answer Don’t be so hard on yourself take it easy
