Answer:
- x + y + z = 500
- 2.50x +1.75y +3.20z = 1172.50
- 0x +y -z = 100
Step-by-step explanation:
Let x, y, z represent the numbers of cheeseburgers, plain burgers, and chicken burgers ordered for the party.
We have three relations given. Each can be used to write an equation.
x + y + z = 500 . . . . . . . . . a total of 500 meals were ordered
2.50x +1.75y +3.20z = 1172.50 . . . . . the total cost
0x +y -z = 100 . . . . . . . . . . 100 fewer chicken were ordered than plain
_____
<em>Additional comment</em>
We put the coefficient of x as 0 in the last equation to facilitate writing this system as an augmented matrix.
The solution is (x, y, z) = (300, 150, 50).

Answer:
3/10
Step-by-step explanation:
3/5 - 3/10 = 5×2 = 10 so 10 is the denominator
6/10 -3/10 = rewrite with a denominator of 10
(6-3)/10 = subtract numerators
3/10 already in simplest form
The answer for this is 15.
