The school cafeteria served three kinds of lunches today to 225 students. The students chose the cheeseburgers three times more

r-ruslan [8.4K]

Let the number of fish sandwiches sold br represented by x

Then the number of grilled cheese sold is 2X

and the number of cheeseburgers 3(2x)

x + 2x + 3(2x) = 225

and solve

Let x represent the no. of pounds of peanuts

Then x + 14 represents the no of pounds of the mixture

And

(2.25)x + (3.25)(14) = (2.65)(x + 14

and solve

3) Try on your own

plz mark me as brainliest :)

Answer:

x = 0

Step-by-step explanation:

3(x - 1) = 2x - 3 + 3x

3x - 3 = 2x - 3 + 3x

0 - 3 = 2x - 3

0 = 2x

2x = 0

x = 0 ÷ 2

x = 0
