Solve for X

4X-(9-3X)=8X-1

Answers

Answer 1

Answer: 4x - (9 - 3x) = 8x - 1

4x - (9) - -(3x) = 8x - 1

4x - 9 + 3x = 8x - 1

7x - 9 = 8x - 1 (-8x from each side)

-x - 9 = -1 (+9 to each)

-x = 8 (divide -1 from each side)

x = -8

Answer 2

Answer:

In the equation, if we are to solve for x, the result would be -8.

How to solve for x

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.

The best answer choice to solve your problem would be B).

Divide both sides by r

Divide both sides by t

I/rt = p

Switch it up ( p = I/rt )

What is a 2 digit number, less than 50 that can be divided by 4 exactly and when 4 is added to it it can be divided by 5 exactly

Answers

ok

divisible by 4 exactly measn that it is even
ends with 0,2,4,6,8

when you add 4 it divides by 5, if it is divisble by 5 it ends with 0 or 5
the possible numbers under 50 that are divisble by 5 are
5,10,15,20,25,30,35,40,45

if you add 4 to the mystery number, you get divisible by 5
minus 4 from all of that list and see which s divisible by 4
1,6,11,16,21,26,31,36,41

the number could be 16 or 36

A scientist needs 10 litera of a 20% acid solution for an experiment but she has only 5% solution and a 40% solution. To the nearest tenth of a liter, how many liters of the 5% and the 40% solutions should she mix to get the solution she needs?

Answers

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

Wayne Inc., a health insurance company, pays clerks an incentive based on the average amount of work completed per hour. Wayne pays $10 for processing 20 invoices per hour. An employee who processes 30 invoices would earn $15 per hour. Hence, Wayne pays the same rate per invoice no matter how many invoices an employee processes per hour. Which type of incentive pay does this scenario illustrate?

Answers

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.
