I know that when you are explaining, you need to add in all of the work that you did.
Given:
In triangle
.
To find:
The value of y.
Solution:
In a right angle triangle,

In triangle BGU,



Isolating y, we get



Therefore, the correct option is A.
Answer:
She would leave a tip of 2.0925 ($2.09)
Step-by-step explanation:
80/60 = (80 + 2x)/(60 + 27)
80/60 = (80 + 2x)/87
4/3 = (80 + 2x)/87
3 . (80 + 2x) = 4 . 87
240 + 6x = 348
6x = 348 - 240
6x = 108
x = 18
We can say that x is the amount of time of the first (easier) part of the hike. Ans t is the amount of time of the second ( more difficult ) part of the hike.
x = 2 - t
And:
3 x + 1.5 t = 5
Answer:
The equation is:
3 * ( 2 - t ) + 1.5 t = 5
We can also solve this equation:
6 - 3 t + 1.5 t = 5
1.5 t = 1
t = 0.66 h = 2/3 h = 40 min.
