7x+2m+25 I believe is the answer
So basically I added the x’s first 3x+4x=7x
Next I added the m’s 7m-5m=2m
That left 25
And a + are left
So the two answers 7x+2m and add +25
7x+2m+25

Answer:

I am about 95% sure that this is what they want. P.s (sorry I cant put the divide symbol)

<u><em>The variable is the number of shirts she bought or x</em></u>

and the equation is <u><em>(375+50) divided by (15+2) = x</em></u>

in the solve spot put

<em><u>(375+50) divided by (15+2)=x</u></em>

<em><u>425 divided by 17=x</u></em>

<em><u>x=25</u></em>

Then your answer would be <u><em>25</em></u>

Step-by-step explanation:

first add 50 to 375 so you get the full price which will give you 425. then to find out how many shirts she bought you must add 2 to 15 to get 17. then divide 425 by 17 which is 25. so she bought <em><u>25 shirts</u></em>.

The two-way table is attached.

We know that 63 people took the survey, and 22 of them were left-handed.  This means that 63-22=41 of them are right handed.

Out of the 63 total, 37 are left brain dominant; this means that 63-37=26 are right brain dominant.

Of the 26 that are right brain dominant, 21 are right handed; this means 26-21=5 are left handed.

Of the 22 left-handed people, 5 are right brain dominant; this means 22-5 = 17 are left brain dominant.

Of the 37 left brain dominant people, 17 are left handed; this means 37-17=20 are right handed.
