Literal equations, simply put, are equations containing two or more variables. Your goal is to solve for just one variable with respect to others. If you know how to solve regular equations, then I guarantee you that solving literal equations will be a breeze.
The "heart" of literal equation is to isolate or keep by itself a certain variable on one side of the equation (either left or right) and the rest on the opposite side.
we know that
The <u>Triangle Inequality Theorem</u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
so
Let
s------> the length of the third side
therefore
<u>The answer part a) is</u>
we know that
the perimeter of a triangle is the sum of the length sides
In this problem
<u>For 
</u>
the perimeter is equal to
<u>For 
</u>
the perimeter is equal to
so
therefore
<u>the answer part b) is</u>
First we have to see in both cases what is the cost of one ticket
in the fist case 12.5/5=2.5
in the second case 20.16/8=2.52
therefore 5 tickets for 12.5 is the better deal
Answer:
Angle 7 and 8 (the first option)
Step-by-step explanation:
Supplementary angles add up to 180 degrees.
Angles 7 and 8 are 180 degrees total.
7 and 8 are supplementary.
1st option

Answer:
x = 5, y = -2
Step-by-step explanation:
<u>Given equations:</u>
<u>From the first equation we get:</u>
<u>Substitute x in the second equation, find y:</u>
- 3x - y = 17
- 3*(1-2y) - y = 17
- 3 - 6y - y = 17
- -7y = 17 - 3
- -7y = 14
- y = -14/7
- y = -2
<u>Find x:</u>
- x = 1 - 2y
- x = 1 - 2*(-2)
- x = 1 + 4
- x = 5
