So say for example u have -7 - (-5), think of subtracting integers as adding the opposite, so ur adding the opposite of -5, the opposite of -5 is 5, so ur adding -7 and 5= -2
another one: -15 - (-18)
again, adding the opposite. -15 plus positive 18= 3
I do not know the last question but I know the first it is4 time I hope I am right
Pretty sure the answer is C since the point is at 1 on the c-axis

For a triangle.
</span>40+3x+4x=180
The other two angles are 60 degrees and 80 degrees.
Answer:
<h2>x = 36°</h2>
Step-by-step explanation:
Since the angles lie on a straight line , it means that they are supplementary to each other. That is the sum of their angles add up to 180°
To find x add up all the angles and equate them to 180
We have
3x + 2x = 180
5x = 180
Divide both sides by 5

We have the final answer as
<h3>x = 36°</h3>
Hope this helps you
