There are 4 terms.
The second term and the fourth term have negative coefficients.
Terms are only negative depending on the value of the variables.
There would be 35 rulers.
In order to solve this, use cross multiplication.
6/10 = 21/x -----> cross multiply
10*21 = 6*x
210 = 6x
35 = x
The answer is C, 1.
In a number line, the larger number it gets, the more of the right side they're. The smaller the number, the more left side they get.
So, on a number line, 1 is just at the right side of 0, all the other options are at least one more place away from 0.

Answer:
<h2><em><u>
t = 15.2 is the answer</u></em></h2>
Step-by-step explanation:
<h2><em><u>
1. Make an equation</u></em></h2>
numbers to find perimeter = perimeter
Side + Side + 2 unknown sides = perimeter
12 + 7.8 + 2t = 50.2
<h2><em><u>
2. Simplify like terms</u></em></h2>
19.8 + 2t = 50.2
<h2><em><u>
3. Solve</u></em></h2>
19.8 + 2t = 50.2
-19.8 - 19.8
2t = 30.4
<h2><em><u>
t = 15.2</u></em></h2>
<h2><u><em>
4. Check:</em></u></h2>
12 + 7.8 + t + t = 50.2
12 + 7.8 + (15.2) + (15.2) = 50.2
<h2><em><u>
50.2 = 50.2</u></em> Correct!</h2><h2 />
Hope this helped,
