Tram left a tip of $9, which was 3/20 of the total cost of the food. which shows the correct equation and value of x, the total cost of the food? x = $1.35 x = $60 x = $1.35 x = $60

the correct equation :

The  value of x= $60

Step-by-step explanation:

Let the total cost of the food be x .

Given that , Tram left a tip of $9, which was of the total cost of the food.

According to this statement , we have

Multiply 20 on both sides , we get

Divide both sides by 3 , we get

i.e.  the total cost of the food = $60

Thus , the correct equation :

The value of x= $60, where x is the total cost of the food.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

the answer is a.

135 and 80
