4x−5=7+4y
subtract 7 from both side
4x - 5 -7 = 4y
4x -12 = 4y
divide by 4
4x/4 -12/4 = 4y/4
x-3=y
Answer:

Answer:
1000000000 ml^3 or 1000000L^3
Step-by-step explanation:
First you have to know that the volume of a cube is found by A^3
A is 1 side of the cube.
Now plug in the number 1000.
1000^3=1000000000 ml^3
To simplify you could turn it into liters. To do this divide by 1000.
This would result in 1000000L^3
Answer: 350
Step-by-step explanation:
Let the cheeseburger be represented by a.
Since there were 51 fewer cheeseburgers sold than hamburgers. This means that hamburgers will be:
= a + 51.
Since the local hamburger shop sold a combined total of 649 hamburgers and cheeseburgers. This will be:
a + a + 51 = 649
2a + 51 = 649
2a = 649 - 51
2a = 598
a = 598/2
a = 299
299 cheeseburger were sold
Therefore, the number of hamburger sold will be:
= 649 - 299
= 350
