Answer: x= 5

Step-by-step explanation: If angles 1 and 2 are supplementary, that means they add up to 180. So if angle 1 is 87, angle 2 has to be 180-87=93. Then the equation would be 15x+18=93. Subtract 18 on both sides. 15x=75. Divide by 15 and your answer is 5.

Help plz ill give extra points
White raven [17]

Answer:

The answer here would be D.

Step-by-step explanation:

When looking at the angle you can see that it is a straight line with a intersecting line. This tells you that you will have supplementary angles, or angles that add up to 180 degrees.

You can only have supplementary angles when they are on either side of a straight line that has been intersected.

Since supplementary angles have to add up to 180 degrees, and you already know that one part of the current supplementary angles is 50 degrees, you can do the math,

180-50=130

To get your answer of D. 130

Solve the following inequality for w then simplify <br> -w+9&gt;6w+8
Alla [95]

Answer:

\displaystyle (-\infty,\frac{1}{7})

Step-by-step explanation:

<u>Inequalities</u>

To solve the inequality:

-w+9>6w+8

We need to perform the required operations on both sides of the inequality to have the variable w isolated.

First, we subtract 9:

-w+9>6w+8

-w>6w+8-9

Subtracting 6w:

-w-6w>+8-9

Operating:

-7w>-1

Now we divide by -7 but recall that when dividing by a negative number, we must flip the inequality sign:

\displaystyle w

Operating:

\displaystyle w

Solution:

\mathbf{\displaystyle (-\infty,\frac{1}{7})}

What is the x intercept of 2x + 4y = 20
zhuklara [117]

Answer:

10

Step-by-step explanation:

x- intercept is where the equation intersect the x-axis. So, at x-axis y = 0

2x + 4*0 = 20

           2x = 20

Divide both sides by 2

2x /2 = 20/2

x = 10
