Answer: T=1/2 Y + -5/2
Step-by-step explanation:
y=2t+5
2t+5 +-5= y +-5
2t=y-5 2t/2=y-5/2
t=1/2y+-5/2
= t=1/2y + -5/2

By using what we know about right triangles, we conclude that the height is 11ft.
<h3>
How far is the top of the escalator from the ground floor? </h3>
We can think of this as a right triangle.
Where the length of the escalator is the hypotenuse
We know that the angle of depression is 42.51°, then the top angle of our right triangle is:
90° - 42.51° = 47.49°
Now, the height of the top of the escalator would be the adjacent cathetus to said angle, then we can use the relation:
cos(a) = (adjacent cathetus)/(hypotenuse)
Replacing what we know:
cos(47.49°) = height/16ft
cos(47.49°) *16ft = height = 10.8ft
Rounding to the nearest foot, we get:
height = 11ft

The original price of the meal deal if they would have exactly enough money to buy two of the meal deal is $4
<h3>How to write and solve equation?</h3>
let
x = cost of the meal
Both = 2x - 3
- Jessica = 3/4x
- Callista = 1/2x
3/4x + 1/2x = 2x - 3
(3+2)x / 4 = 2x - 3
5/4x = 2x - 3
5/4x - 2x = - 3
(5-8)x/ 4 = -3
-3/4x = -3
x = -3 ÷ -3/4
= -3 × -4/3
= 12/3
x = $4
