On Monday, a localamburger shop said a combined total of 225 hamburgers and cheeseburgers. The number of cheeseburgers sold was

zheka24 [161]

Answer:

h = hamburgers sold

2h - 72 = 578

2h = 650

2 2

h = 325

There were 72 fewer cheeseburgers sold than hamburgers. That means cheeseburgers = 325 - 72

325 - 72 = 253

253 = cheeseburgers

325 = hamburgers

253 + 325 = 578

Hamburgers = 325

Hope this helps :)

Vlad [161]

Answer: $P=5y+11x$

Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

- By definition, the perimeter of the figure is the sum of the lenght of each side. Then, you must make the addition as following:

$P=2.8y+2x+2.2y+5x+4x$

Where $P$ is the perimeter of the figure.

- Add the like terms, then, you obtain the following expression in simplest form:

$P=5y+11x$

One number is 3 more than another number. if you add 12 to 4 times the first number, the result is 5 times the second number. Fi

aleksklad [387]

Answer:

first is -3, second number is 0

Step-by-step explanation:

you have two equations x+3=y and 4*x+12=5*y

Use the first one and write y in terms of x in the second equation:

4*x+12=5*(x+3)

4*x+12=5*x+15

12=5*x-4*x+15

12=x+15

x=-3
