Answer 2

Answer

6.5y+10

Step-by-step explanation:

Let's simplify step-by-step.

0.5y+10.5+6.5y−0.5−0.5y

=0.5y+10.5+6.5y+−0.5+−0.5y

Combine Like Terms:

=0.5y+10.5+6.5y+−0.5+−0.5y

=(0.5y+6.5y+−0.5y)+(10.5+−0.5)

=6.5y+10

Marcy split her income from last week equally between paying her student loans, rent, and savings. She put $300 in savings. How much did
Marcy earn last week?

?/3 =

Marcy earned $___ last week

Answers

Answer:

x/3 == 300

Marcy earned $900 last week.

Step-by-step explanation:

For this problem let's consider that 3 equal parts, or "split her income from last week equally" is 3 parts of her entire paycheck.

So she put $300 into savings which is x/3, if we let x represent the amount in dollars of her entire paycheck.

Then we can say the following:

If x / 3 == $300, then x == $900.

x / 3 == 300

( x / 3) * 3 == 300 * 3

( x * 3 / 3 ) == 300 * 3

x == 300 * 3

x == 900

So you can say the following:

x/3 == 300

Marcy earned $900 last week.

Cheers.

x/3
X=300
so Marcy earned $300

Step-by-step explanation:

if this is useful please make me brainliest

60 fin 40 didnot

**Explanation:** Most of the time, people use percentages to express a fraction or a portion of a whole. In fact, percent literally means "per 100" or "out of 100." So when you see 25 percent, for example, you could read it as "25 out of 100" or "25 per 100 parts." But you can also have percentages that are greater than 100 percent – and when that happens, there's at least one complete whole, or a whole number, hidden in there somewhere.

Answers

Answer:

Step-by-step explanation:

The best prediction of the total number of pages in a book with 4 chapters could be 120 pages.

How does the dot plot work?

Suppose we're measuring something whose values are numeric. For each value of that thing we observe, we plot a dot above that value in the number line. Thus, the total number of dots in the dot plot tells us the total number of observations of the values of that thing we did.

We have been given that Students recorded the total number of pages and chapters in each of several books on the scatterplot.

Based on the scatterplot, we need to find the best prediction of the total number of pages in a book with 4 chapters.

According to the scatterplot, we can see that the closest number to the pattern seems to be between 100 and 120.

Therefore, the best prediction of the total number of pages in a book with 4 chapters could be 120 pages.
