Answer:
1/10 cup of frosting
Step-by-step explanation:
If it takes 7/10 cups of frosting to decorate 7 cupcakes, then one cupcake is (7/7)/10=1/10 cup
Proof: 1/10+1/10+1/10+1/10+1/10+1/10+1/10=7/10
Also: 7(1/10)=7/10
Hope that makes sense!
Answer:
y= -4
Step-by-step explanation:
x+y=42. We know that x plus y equals 42.
x=2y . We also know that x equals twice y.
2y+y=42. Since we know that x=2y, we're going to replace x with 2y from the original equation, simplified would be 3y=42.
y=14. 3y=42 simplified is y=14, this is because we divided both sides by 3 (since 3 and 42 are both divisible by 3) (btw divisible by 3 simply means that it can be divided by 3)
x+14=42. Now that we know what y equals, let's replace y with 14 from the original equation.
x=28. Now that we know that x=28 and y=14, we know that y is always x/2.
When x=-8, we divide it by 2 and get, -4.
Not absolutely positive as this was all mental math, but hope this helps! :)
B, because nothing repeats.
