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:
16% or 4/25
Step-by-step explanation:
16 + 5 = 21
25 - 21 = 4
4/25 = 16%
This is right because 21/25 is 84% and 84% + 16% = 100%
Answer:
105.5 degrees
Step-by-step explanation:
Quadrilaterals always equal 360 degrees total
You already have 101 degrees + 48 degrees = 149 degrees
So take the 149 degrees away from 360 degrees: Now you have 211 degrees
Angles 1 and 2 have the same angle, as indicated by their matching line
So divide 211 degrees by 2, which = 105.5 degrees
