A straight line has two angles 1 and 2. The measure of angle 1 = 35 degrees, find the measure of angle 2.
First lets draw out our straight line. If we made two angles out of our straight line with one being 35, how can we find our other angles measurement? Angles on the same line are called supplementary angles which means that the angle measurements all together should add up to the measurement of a straight line. The measurement of a straight line is always 180 degrees. Therefore, if one of the two angle measurements is 35 we can then subtract that from 180 to find our missing angle. The equation will be 180 - 35 = 145, so the measurement of angle 2 equals 145 degrees.

The student had 6 stickers and then the teacher gave the student 8 more stickers. How many stickers does the student have now?
The student began with 6 stickers. Then the student received 8 more stickers. If we draw 6 stickers and then draw 8 more, how many do we have all together? After drawing out our picture we can then create an equation 6 + 8 = 14. The student has 14 stickers total.
Solve for X. 6x+3=8x-21
First lets remember to use our D.C.M.A.M which stands for Distribute, Combine like terms, Move the smaller variable, Add/Subtract, and then Multiply/Divide. With that in mind since we have nothing to distribute or combine on one side we then move over the smaller variable to combine like terms together. To move over the variable we must subtract 6x from the left and whatever we do to one side we do to the other. Therefore, 6x minus 6x on the left will cross out and then 6x minus 8x will be 2x. Then, we will need to do the same with our constants which are the numbers without variables. We can add 21 to the right side so that it can cancel out and then add it to the other side. After, we can add 21 and 3 together to get 24. Now we use our division and divide 2 from the left side to get our variable X alone. Remember what we do to one side we have to do to the other. So 24 divided by 2 equals 12, which means X=12.
