Let's say

is the measure of the first angle and

is measure of the supplement of

. We know that supplementary angles add up to 180°, so

. We also know that

. Therefore,

. It follows that

, therefore, the first angle is 174° and the second angle is 6°.
Answer: 
Step-by-step explanation:
The area of a rectangle can be found with the following formula:

Where "l" is the length and "w" is the width.
In this case you can identify in the figure given in the exercise that:

You know that the area of that rectangle is the following:

Therefore, knowing those values, you can substitute them into the formula and then you must solve for "x" in order to find its value. You get that this is:

Answer:
5x+14
Step-by-step explanation:
combine 7x and -2x
combine -10 and 24
Do you remember how to graph an equation ?
There are two of them here. Each one is a straight line on the graph. The "solution" of the pair of equations is the point where the two lines cross.
It might help you draw the graphs if you solve each equation for 'y' first.
-- The first one is y = -x - 4 .
-- The second one is y = -3x - 6 .
-- Graffum both.
-- Find the point where they cross.
