Biochemistry lab is worth 25% of your total mcb 2000 course grade. of that 25%, the weekly laboratory reports account for 45%. from this 45%, 10% is for participation and 90% if from the actual laboratory report score. you will be submitting a total of nine laboratory reports over the course of the semester. based on this information, each laboratory report is worth of your total grade for the mcb 2000 course. enter your answer in numeric format: 1, 2, 3, etc. (round to the nearest whole number)

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%

can someone answer this question plz

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
