The second equation because they all have a common factor of 3. You can get x by itself. However, with the first one, you'll end up with fractions instead.

Serjik [45]

Answer:

5.1 pints

Step-by-step explanation:

Theres 2 ways

First way:

We can do 2/5 of 8.5 which is 3.4. Then, we can subtract 3.4 from 8.5 and get 5.1 pints.

Second way:

We can simply do 3/5 of 8.5 because the remaining 3/5 of the paint is blue. 3/5 of 8.5 is 5.1 pints

Quiana has 5 times more text messages from Yolanda than from Pierre. Quiana has 30 text messages from Yolanda. Which equation ca
VladimirAG [237]

Answer:

p=\frac{30}{5}

Step-by-step explanation:

Quiana has 5 times more text messages from Yolanda than from Pierre, we also know that she actually has 30 text messages from Yolanda. In other words, 30 texts from Yolanda is 5 times more text messages than from Pierre.

Thus, if we call p the number of texts messages from Pierre we would have that

p=\frac{30}{5} (since 30 texts from Yolanda is 5 times more than p, we can divide by 5 to find p)

And if we solve this equation we would get that Quiana has 6 text messages from Pierre
