8/2.79 = 1/2.867, or $2.86 per each oz
15/5.54 = 2.707/1, or 2 oz for every 1 dollar
the 15 oz jar of salsa has the better unit rate
hope this helps
Well first you have to make the denominators equal by finding a common denominator. in this case 21, but whatever you do to the bottom you do to the top. so 1/3 times 7/7 equals 7/21 and 1/7 times 3/3 equals 3/21.
so how many 7/21 cups of ice cream can you make from 3/21 i think about none but remember i could be wrong
Simple...
you have:

and

To solve for....

Multiply to remove the denominator-->>

n=12*3
n=36
Then-->>>

Do the same thing-->>

n=-12*3
n=-36
Thus, your answer.
Answer:
i= -6
Step-by-step explanation:
-5i-15=15
if we use inverse operation here, it would be -5i=30, so i= -6
R=3 this is the answer...
