In the equation, if we are to solve for x, the result would be -8.
To solve for x in the expression, the first step would be to collect like terms. Thus, we would have;
4x - (9 - 3x) = 8x - 1
4x -9 + 3x = 8x - 1
Collect similar terms
4x + 3x - 8x = -1 + 9
-x = 8
Divide both sides by -1
x = -8
So, the value of x in this equation is -8.

Answer:
The best answer choice to solve your problem would be B)
Step-by-step explanation:
first: Divide both sides by r
then: Divide both sides by t
x = liters of 5% solution
y = liters of 40% solution
The scientist wants 10 L total of a 20% solution, so
x + y = 10
0.05 x + 0.40 y = 0.20 (x + y) = 2
From the first equation,
y = 10 - x
Substitute this into the second equation and solve for x :
0.05 x + 0.40 (10 - x) = 2
0.05 x + 4 - 0.40 x = 2
2 = 0.35 x
x ≈ 5.714 L
Solve for y :
y = 10 - x
y ≈ 4.286 L

Answer: Straight piecework plan
Step-by-step explanation:
The Straight piecework plan is a type of incentive system in which the rate per unit output is constant and fixed at a specific value. And the total earnings of a worker is calculated by multiplying the value of its total output by the rate per unit output.
In the case above the rate per unit invoice processed is fixed, so employees are paid based on the number of invoice processed per hour which makes it a Straight piecework plan system.
