**Math**

Pentagons are five sided figures, in which each of the five sides are equal. To figure out the perimeter, you take the side given and multiply it by 5 since each side is the same. I'll do the first one for you and you can do the rest. 6 * 5 = 30.

8.5>6.1+0.6y Subtract 6.1 from both sides 2.4>.6y Divide both sides by .6 4>y or y<4 To graph this, find where y=4, and draw a line across this point. Since y<4, you will then shade below the line.

The angles with measure the same..the side lengths and perimeter will be comparable by ratio.

To make it plural doesn't mean to add is or ies to each words. Plural means more than one. I'm sure you know the plural for day. 1 day + 1 day = 2 _____. Try them again and then I (or someone else) will check your answers. They are almost all wrong.

2 * 3 * 4 * 5 * 6. I just used guess and check. It didn't take that long. If you're unsure of what the words mean, you should look them up. Consecutive means in order and integers means whole numbers.

Some of those are right and some of those are wrong. I'll show you one that you got wrong. First you put it over 100 and then you reduce. 44%=44/100=11/25

When you have a < sign you either shade under or to the left of the line, depending on what kind of line it is. It has a dotted line. A > sign you shade either to the right or above the line. This also has a dotted line. If you have a <= or >=, the line is solid.

Right now the probability of picking blue would be 12/30. If you add another blue it would be 13/31, then 14/32, 15/33, 16/34, 17/35, 18/36. 18/36=1/2, so if he wants the probability to be 1/2 he needs to add 6 more blue.

Yup, 105-79, because you have to take the highest number and lowest number and subtract them.

A much easier way to do this would be: 1) x+y=1300 2) x+2z=1400 3) x+y+z=1600 Look at 1 and 2. Since x+y=1300 and x+y+z=1600, z obviously equals 300. Now substitute that back in #2. x+2(300)=1400, x+600=1400, x=800. Now substitute x and z back in #3. x+y+z=1600, 800+y+300=1600...
