Answer:
<h2>5 1/4</h2>
Step-by-step explanation:
3 1/2 = 6/2 + 1/2 = 7/2
He drinks 3 1/2 liters every 2/3 hour means
He drinks (7/2)×(3/2) = 21/4 = 5 1/4 liters in one hour.

Answer:
A. $56
Step-by-step explanation:
the change of cost =
[7(10) + 28] - [7(2) + 28] = 98-42=56
Answer:
f^-1(x) = 1/4 x - 7/4
Step-by-step explanation:
f(x)=4x+7
Inverse:
x = 4y + 7
4y = x - 7
y = 1/4 x - 7/4
Answer
f^-1(x) = 1/4 x - 7/4
The trick is to recognize a few things.
1. These are similar triangles, so the ratio of BU to BC is the same as BT to BA and UT to CA.
![\dfrac{BU}{BC}=\dfrac{BT}{BA}=\dfrac{UT}{CA}](https://tex.z-dn.net/?f=%5Cdfrac%7BBU%7D%7BBC%7D%3D%5Cdfrac%7BBT%7D%7BBA%7D%3D%5Cdfrac%7BUT%7D%7BCA%7D)
2. BC = 2 BUs and BA = 2 BTs
This means the sides of the short triangle are half the length of the sides of the big triangle.
Put in other words, CA = 2 UT
Put into an equation x+29 = 2(x+19).
x + 29 = 2x + 38
–9 = x
So that means UT = 10 and CA = 20
