Sum means addition
negative 18 means -18
a number can be x
Sum of negative 18 and x should be 11
thus the equation is
<span> Measure and compare pencil lengths to the </span>nearest<span> and of an </span>inch<span>, and analyze the data through </span>line<span> plots. I should measure my pencil and see which </span>half-inch<span> or whole-</span>inch<span> mark is </span>closest<span> to the </span>length<span> of my strip</span>
In order to solve the equation, set up a proportion. Use the similar sides together!
1. 16/8 = x/20.... Similar sides are in one ratio and they equal another ratio...."x" represents the side of VS
2.Solve for "x" by cross multiplying: 8x = 320
3. Divide by 8 to find "x": x = 40
Side VS equals 40. Hope this helped :)
5x = 14 where x is the unknown number
divide both sides by 5:-
x = 14/5 or 2 4/5
