Answer:
Answers: 1) gh= -7×3= -21
2) g2-h= -7×2-3= -17 *that is what I got from my calculations.
3) g+ h2 = -7+3×2= 1 *that is what I got from my calculations.
4) g+h = -7+3 = -4
5) h-g= 3--7= 3+7= 10
6) g-h= -7-3= 10
Step-by-step explanation:
I don't fully understand neither but I tried.
Answer:
28%
Step-by-step explanation:
25 is 1/4 of 100, so it would be 7*4 which is 28
Solution:
Let the distance of house from the theater be x miles.
Total travelling time
Then average speed
Terrence walks at a pace of 2 mi/h to the theater and back home at 40 mi/h.
So Average Speed mi/hr
Both the average speed should be equal. So we can write
Hence the distance from home is 13.125 miles.
Answer:
C. Vertical angles are supplementary if both are right angles.
Step-by-step explanation:
You want to know the conditions when vertical angles are supplementary.
<h3>Supplementary angles</h3>
Two angles are supplementary when they total 180°.
<h3>Vertical angles</h3>
Vertical angles are formed when two lines cross. They share a vertex, but not a side. Their sides are opposite rays.
Vertical angles are always congruent.
<h3>Supplementary vertical angles</h3>
If x is the measure of one of two supplementary vertical angles, then we must have ...
x + x = 180°
2x = 180° . . . . . collect terms
x = 90° . . . . . . . divide by 2
Vertical angles will be supplementary if and only if they are both right angles.
