Suzanne bought 6 paint sets. Each set contains the same number of brushes. She has 18 brushes. Write and solve an equation to de

PSYCHO15rus [73]

Answer:

Step-by-step explanation:

Given that:

The number of paint sets, Suzanne bought= 6

As each set contains the same number of brushes.

Let x be the number of brushes each set contains.

So, the total number of brushes in 6 sets = 6x.

It is given that the total number of brushes she has is 18, which is equals to 6x.

So, the required equation is

$6x=18$

$\Rightarrow x=\frac {18}{6}$

$\Rightarrow x=3.$

Hence, the number of paint brushes each set contains is 3.

Can anybody tell me what is a stem-and-leaf plot and a example

zhannawk [14.2K]

The following examples provide some practice with stem-and-leaf plots, as well as explaining some details of formatting, and showing how to create a "key" for your plot.

<span> Subjects in a psychological study were timed while completing a certain task. Complete a stem-and-leaf plot for the following list of times: </span>

7.6, 8.1, 9.2, 6.8, 5.9, 6.2, 6.1, 5.8, 7.3, 8.1, 8.8, 7.4, 7.7, 8.2

The first thing I'll do is reorder this list. It isn't required, but it surely makes life easier. My ordered list is:

5.8, 5.9, 6.1, 6.2, 6.8, 7.3, 7.4, 7.6, 7.7, 8.1, 8.1, 8.2, 8.8, 9.2

These values have one decimal place, but the stem-and-leaf plot makes no accomodation for this. The stem-and-leaf plot only looks at the last digit (for the leaves) and all the digits before (for the stem). So I'll have to put a "key" or "legend" on this plot to show what I mean by the numbers in this plot. The ones digits will be the stem values, and the tenths will be the leaves.
