What is 13x - 7y + 4x?
AlladinOne [14]
17X-7Y. You add or subtract the same variables, in this case you only have two x's and one y. So you add them, because you have a addition sign. 13x+4x and you leave the Y alone, because there is not another Y variable.

If 1/a + 1/b =1/c and ab=c,what is the average of a and b?
goblinko [34]
If we solve the left side of the given equation,
                                  1/a + 1/b = 1/c
 we get an answer of,
                                    b+a / ab = 1/c
Since ab = c, we can conclude that b + a is 1. The average of these two numbers is equal to there sum divided by 2. The answer is therefore equal to 0.5.

A rectangular painting is 24 inches wide and 20 inches tall without the frame. With the frame, it is 28 inches wide and 24 inche
evablogger [386]

The area of the frame not covered by the painting is 192 square inches

<em><u>Solution:</u></em>

Given that, A rectangular painting is 24 inches wide and 20 inches tall without the frame

The area of rectangle is given as:

Area = length \times width

<em><u>Find the area of painting without frame:</u></em>

Length = 20 inches

Width = 24 inches

Area\ Without\ Frame = 20 \times 24 = 480

Thus area of painting without frame is 480 square inches

With the frame, it is 28 inches wide and 24 inches tall

<em><u>Find the area of painting with frame:</u></em>

Length = 24 inches

Width = 28 inches

Area\ with\ frame = 24 \times 28 = 672

Thus area of painting with frame is 672 square inches

<em><u>What is the area of the frame not covered by the painting</u></em>

Area of the frame not covered by the painting = Area with farme - Area without frame

Area of the frame not covered by the painting = 672 - 480 = 192

Thus the area of the frame not covered by the painting is 192 square inches
