Answer:
1
Step-by-step explanation:
because the triangles are isosceles, that means that the area of Z is 5x5x1/2, which equals 12.5
the area of X is 4.5
the area of y is 8
(8+4.5)/(12.5) = 1
Company A : 220 + 65h
Company B : 300 + 55h
How many hrs they will cost the same.....so set them equal to each other and solve for h(the number of hrs)
220 + 65h = 300 + 55h
65h - 55h = 300 - 220
10h = 80
h = 80/10
h = 8
220 + 65(8) = 740
300 + 55(8) = 740
so in 8 hrs, both companies charge $ 740
Answer:
No Solution
Step-by-step explanation:
Jason starts riding a bike 1 mile from the station.
Shawn starts biking 2 miles from the station.
For Jason to reach Shawn, he needs to go at a higher speed. However we know that they are going at the same constant speed. Then they will never meet.
To prove it we propose the following system of equations. Where x is the hours and y is the distance in miles.
For Jason we have:

For Shawn
.
We want to know when Jason and Shawn are at the same distance.
Then we write the following eqution and clear x:

Equality is not satisfied. Therefore, it has no solution.
I mean Jason and Shawn will never be the same distance
Answer:
Step-by-step explanation:
4(x-3)2-5 = 139
(4x-12)-5=139
-20x + 60 = 139
-20x +60 - (60) = 139- 60
-20x = 79 divide both sides by -20
x = -3.95
