You went to lunch with your friend, and the bill was $19.00. your lunch is $3.00 more than your friend's. how much was your friend's lunch?

$8

Step-by-step explanation:

The  cost of your lunch added to the cost of the lunch of your friend gives the total cost stated in the bill.

If the cost of your lunch is $3.00 more than your friend's and your friend's lunch is y in $, then the cost of your lunch will be

= y + 3

The sum

= y + y + 3

= 2y + 3

Equating to the bill amount

19 = 2y + 3

2y = 19 - 3

2y = 16

y = 8

the cost of your friend's bill was $8

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.
