Help!!! Will give brainliest!!

Mathematics
1 answer:
Serhud [2]3 years ago
7 0

the sum of three angles of a triangle adds up to 180 degrees. In this problem, you are given two angles.

x+(2x+15)+the measure of angle Q should equal 180.

Since everything is addition, the parenthesis can be removed.

x+2x+15+Q=180. This can then be simplified to 2x+15+Q=180. Subtract 15 from both sides to get 2x+Q=165. Divide both sides by two to get the x by itself. x+Q=82.5.

Unfortunately I don't really know what to do from here, but I hope it helped at least a little.

Give an equation that goes through the line 3,-1 that is parallel to 6x-5
allochka39001 [22]
Lines that are parallel have the same slope, and the given line (y = 6x - 5) has a slope of 6; we are looking for a line with a slope of 6.
To form an equation for a line, you need to know the y-intercept (the point at which the line intersects the y-axis). The first step to finding the y-intercept is to plot the given point. After you've done that, count six units up (this is our slope) and one to the right; plot the point. Lastly, draw the line by connecting the points and see where the line intersects the y-axis.
My graph shows that the line intersects the y-axis at -17. All that's left now is to put our information together into an equation. I'm assuming the problem wants the equation in slope-intercept form; slope-intercept form is y = mx + b where m is the slope and b is the y-intercept, so it would look like this:
y = 6x -17

Hope this helps.

Solve for the variable: -4h + 2 = 18 <br> A. -4<br> B. -2<br> C. 1<br> D. 6
Anna [14]
You need to isolate the variable <em>h</em>. 

1) Subtract both sides by 2. 

-4h + 2 = 18
-4h + 2 - 2 = 18 - 2
-4h = 16

2) Divide both sides by -4 (the coefficient). 
(-4h) / -4 = 16 / -4
h = -4
