Answer:
a. x + 4y = 160
b. 160
c. 40
Step-by-step explanation:
a. We can define the variables as ...
x = number of 1/2-liter bottles
y = number of 2-liter bottles
For the total number of liters to be 80, we require
1/2x + 2y = 80
We can multiply this by 2 to eliminate the fraction.
x + 4y = 160
__
b. The x-intercept is 160. It is the number of 1/2-liter bottles required when no 2-liter bottles are used.
__
c. The y-intercept is 40. It is the number of 2-liter bottles required when no 1/2-liter bottles are used.

Solving the algebraic equations given, the missing numbers in the boxes can be known as shown in the steps below.
Given the equation, ⅔(x - 1) = ⅕(2x - 3) + 1
First, apply the distribution property to open the bracket.
Thus:
⅔x - ⅔ = ⅖x - ⅗ + 1
⅔x - ⅔ = ⅖x + ⅖
- Subtract ⅖x from both sides
⅔x - ⅖x - ⅔ = ⅖
4/15x - ⅔ = ⅖
4/15x = ⅖ + ⅔
4/15x = 16/15
- Multiply both sides by 15/4
x = 16/15 × 15/4
x = 4
Given the equation, 3c - 3 + 2(3c + 1) = - (3c + 1)
- Open the bracket using distributive property
3c - 3 + 6c + 2 = -3c - 1
9c - 1 = -3c - 1
9c + 3c - 1 = -1
12c - 1 = -1
12c = -1 + 1
12c = 0
c = 0

Answer:
The value of x is 11.5
Step-by-step explanation:
Here, we want to find the value of x
Since Q bisects PR, it means it divides PR into ii equal angles
Thus PR = PQ
28 = 2x + 5
2x = 28-5
2x = 23
x = 23/2
x = 11.5
