Answer:
Concept: Algebraic Representation
- You have a daily pay or a y-intercept of 20
- Then you have a variable change such that 0.50 is earned for each additional pizza
- Hence the representation is <em>y</em><em>=</em><em>0.50x</em><em>+</em><em>20</em>
- X represents pizzas sold and y represents total pay
Answer: 18, 19, 20
Step-by-step explanation:
3 consecutive integers = x, y and z
1st number is X
2nd number is Y which is X +1
3rd number is Z which is X +2
Write equation
X + 2Y = 16 + 2Z
Replace Y with X + 1 and Z with X + 2
So,
X + 2(X + 1) = 16 + 2(X + 2)
Distribute
X + 2X + 2 = 16 + 2X + 4
Combine like terms
3X + 2 = 2X + 20
Solve for X
3X + 2 - 2 - 2X = 20 + 2X - 2X - 2
X = 18 so, Y is 19 and Z is 20
I'm not sure if it's right, but I think the answer is 648.
Answer:
x=4
Step-by-step explanation:
-x=-3x+8
-x+3x=-3x+8+3x
2x=8
2x/2 = 8/2
x = 4
