Answer:
x + y + z = 5002.50x +1.75y +3.20z = 1172.500x +y -z = 100Step-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

Additional comment
We put the coefficient of x as 0 in the last equation to facilitate writing this system as an augmented matrix.

What is the measure of the angle
Answers
Hey! The measure of the angle is 127
The angle is a total of 180 degrees.
We have to find the total of what's in between the two blue lines.
To make it easier, we can take the total of what's not in the blue lines, 53, and subtract it from 180. This gives us 127. So in between both the blue lines, measures 127. Or, you can just count up from 53 to 180 individually.
