The desired value will be the solution to the equation ...
... (5 - a) = 20 + (6a - 1)
... 5 - a = 19 + 6a . . . collect terms
... 5 = 19 + 7a . . . . . . add a
... -14 = 7a . . . . . . . . . subtract 19
... -2 = a . . . . . . . . . . . divide by the coefficient of x
The value of the variable is -2.
I think the 3rd one, please let me know if I'm wrong. I don't want to give others the incorrect answer.
Step-by-step explanation:
2 x -3 <u>(</u><u>x)</u><u> </u>- 1 <u>(</u><u>y)</u><u> </u>- 2 x -1 <u>(</u><u>z)</u><u> </u>= -5
Answer:
The diameter of the bacterium is 4.05 times the diameter of the plant cell
Step-by-step explanation:
The given parameters both represent diameters
Plant Cell P = 1.26m
Bacterium B = 5.1m
First write out both expressions:
P = 1.26
B = 5.1
Divide B by P
5.1 / 1.26 = 4.04762 Round to 4.05
Multiply both side by P
P * B/P = 4.05 P
B = 4.05 P
This shows that the diameter of the bacterium is 4.048 times the diameter of the plant cell.
First I added 2.5+4.25=6.75
Then do $54/6.75=$8
Answer=$8
