Rolando's Labrador retriever had 12 puppies. Eight of her puppies were yellow labs and the rest were black labs. What is the rat
natta225 [31]

Answer:

1:2

Step-by-step explanation:

There are 12 total puppies. To find the number of black puppies, we have to subtract the yellow from the total. So:

12 - 8 = 4

There are 4 black puppies. Now we put the black puppies in ratio to yellow puppies:

4:8

Then simplify (divide both sides by 4):

1:2

-112=16e<br> Solve for e
snow_tiger [21]

Answer: -7 = e

Step-by-step explanation: To solve this equation for <em>e</em>, we need to get <em>e</em> by itself on the right side of the equation. Since <em>e</em> is multiplied by 16, in order to get <em>e</em> by itself, we need to divide by 16 on the right side of the equation. If we divide by 16 on the right side of the equation, we must also divide by 16 on the left side of the equation.

On the right side of the equation the 16's cancel and we have <em>e</em>. On the right side of the equation -112 divided by 16 is -7. Remember that a negative divided by a positive is a negative.

So we have -7 = e which is the solution to our equation.

To check our solution, we can plug -7 in for <em>e</em> in the original equation. So we have -112 = 16 (-7) or -112 = -112 which is a true statement so our answer checks.
