Answer:

The correct unit rate would be 13 minutes/6 problems (written like a fraction)

or it could be 1 problem/2.17 minutes

Step-by-step explanation:

Unit rates are just a time frame over a measurable occurrence, like math problems or distances. The most common example of a unit rate would be speed limits, like 15 miles/1 hour. So to make a unit rate out of the word problem you simply write out the numbers and units like a fraction, and simplify it if necessary.

Answer:

10x + 6

Step-by-step explanation:

When distributing, you need to multiply the number on its own by both terms of the binomial (the 5x + 3). 5 times 2 is 10, and then you have the x, so it is 10x. Multiply 3 times 2 and get 6. Hope this helps!

How can you understand porportions

BlackZzzverrR [31]

A proportion is a statement that two ratios are equal. A ratio is a comparison of two different quantities. "Miles per hour" is a ratio. "Dollars per pound" is a ratio. A proportion is that two of these things are equal.

For example, paying $2/pound for apples is the same as paying $6 for 3 pounds:

$\dfrac{\$2}{1 \text{ pound}} = \dfrac{\$6}{3 \text{ pounds}}$

That's a portion.

When working with proportions in word problems, you start by setting up one ratio/fraction where you know all the information. You then set up the second one that's missing a piece of information, but you make sure to set it up using the same structure.

If your first ratio is "miles over hours," then the next ratio has to have the same organization.

If your first ratio is "rise over run," then the next ratio has to have the same organization.
