1.

a. Perimeter of the Picture would be all the sides added up all together. Since it's a 5in. by 7in. picture we know that two sides equal 5 inches and the other two sides equal 7 inches.
5+5+7+7=
10+14=
24 inches

b. If I'm understanding correctly then ...
There is a 1 inch between the picture and the frame.
Thus, each side of the picture has two added inches (one inch on the right and left side)

So, the sides with 5 inches now have two inches extra resulting in its length becoming 7 because 5+2=7
The other two sides with 7 inches now have two extra inches as well. Now becoming nine inches in length.

The frame is determined to be a 7in. by 9in.
Just like we did with the picture, we know add up all the sides.
7+7+9+9=
14+18=
32inches


Hope I didn't mess up for your sake!

Ok.... so the first part is asking you what the perimeter of the picture itself is.
The picture is 5in by 7in.... SO you add 5+5+7+7=24.... So the perimeter of the pic is 24 inches.

Now part b

So the frame is one inch thick
This mean that the sides are now 2 inches longeron each side

 SO we have 7+7+9+9=32

So the perimeter is 32

I hope that helped!!!!! If you dont understand something ask and i will reexplain ;)

1) Find x, if 1/3 of x is 14
BartSMP [9]

"of" means multiply      and         "is" means equal

1. \frac{1}{3}x = 14

                                x = 14(3)      <em>multiply both sides by 3 to isolate "x"</em>

                                x = 42

2. \frac{1}{5}x = 14

                                x = 14(5)      <em>multiply both sides by 5 to isolate "x"</em>

                                x = 70

3. \frac{2}{5}x = 14

                                2x = 14(5)      <em>multiply both sides by 5 </em>

                                2x = 70

                                  x = 35         <em>divide both sides by 2 to isolate "x"</em>

4. \frac{7}{8}x = 14

                                7x = 14(8)      <em>multiply both sides by 8 </em>

                                7x = 112

                                  x = 16         <em>divide both sides by 7 to isolate "x"</em>

jasenka [17]
<span>3x = y + 7

<span>8x = 2y + 5
</span><span>8x = 2(3x-7) + 5
8x=6x-14+5
8x-6x=-9
