Answer:
AND
Step-by-step explanation:
I think the plus sign is supposed to be a x. The attached image contains the work.
We have 128 ounces = 1 gallon ⇒ 1 ounce = 1/128 gallon
⇒ 8 ounces = 1/16 gallon
So 1/16 × $3.80 = $ 0.2375 ⇒ 8 ounces of milk costs $ 0.2375
Answer:
y = 20/3
Step-by-step explanation:
4y + 2y + 10 = 50
Combine like terms on the left side.
6y + 10 = 50
Subtract 10 from both sides.
6y = 40
Divide both sides by 6.
y = 40/6
Reduce the fraction by dividing the numerator and denominator by 2.
y = 20/3
