Answer:
a) y-7=-4(x-2)
B) I don't know how to put a graph on brainly :/
You would solve this by writing it as a porpotion. It would be 25/100=161.25/x. Then, you would multiply the 100 and 161.25, which would get you 16125, then you would divide this by 25, which would get you your answer : $645.
The answer to 29×97 would be 2813
Answer:
They need to wash 72 cars
Step-by-step explanation:
2000 - 1640 = 360
360/5 = 72
From A draw the altitude AH intersecting BC in H
Let's prove that triangle ABH is congruent to triangle ACH
The above 2 triangles are right triangles due to the altitude AH
Angle B= Angle C (given)
Angle AHB = Angle AHC =90° (since AH is the altitude)
Then angle BAH = CAH (both complementary to B & C respectively
And AH is a common side
Now Tri. ABH = Tri. ACH because ASA, hence AB=AC
