Solve 3kx + 24 = 9 kx for x.

uranmaximum [27]

Answer:

Step-by-step explanation:

3kx + 24 = 9kx

First subtract 3kx to both sides.

24 = 9kx - 3kx

24 = 6kx

Divide both sides by 6

24/6 = kx

4 = kx

Divide both sides by k.

4/k = x

Biochemistry lab is worth 25% of your total MCB 2000 course grade. Of that 25%, the weekly laboratory reports account for 45%. F

Oksi-84 [34.3K]

Answer: 1%

Step-by-step explanation: Total 2,000

BioChem Lab: 25% of total = 25% . 2000 = 500

LabRep: 45% of Lab = 45% . 500 = 225

There will be 9 LabRep: 225/9 = 25

Participation: 10% of LabRep = 10% . 25 = 2.5

Actual LabRep: 90% of LabRep = 90% . 25 = 22.5

So, each lab report is worth 22.5 of 2000 = 2.5/2000 = 0.01125 = 1.125%

Nearest whole number = 1%
