Answer:
x=1 y = -1/2
(1,-1/2)
Step-by-step explanation:
7x-2y=8
5x+2y=4
I would use elimination since we have 2y in one equation and -2y in the other
7x-2y=8
5x+2y=4
--------------------
12x = 12
Divide each side by 12
12x/12 = 12/12
x =1
The substitute back into equation 2
5(1) +2y = 4
5 +2y = 4
Subtract 5
5-5+2y = 4-5
2y = -1
Divide by 2
2y/2 = -1/2
y = -1/2
Answer:
73.9
Step-by-step explanation:
multiply 5.50 by 8 and 14.95 by 2
EDIT: then add the products together
Answer:
Area = 55 cm2
Step-by-step explanation:
It the base of the parallelogram was 9 centimeters and increased by 2, the new base has 9 + 2 = 11 centimeters.
It the height of the parallelogram was 4 centimeters and increased by 1, the new base has 4 + 1 = 5 centimeters.
Now, we can calculate the area of the parallelogram using the formula:
A = b * h
Where A is the area, b is the base and h is the height. So:
A = 11 * 5 = 55 cm2
Anarchie ist die richtige Antwort
At first, pg means picogram
A microgram is a unit to measure the mass
Then from both relation
Now we can solve the question
Since the average mass per cell is 67.55 pg
Since the number of cells is 10^5
To find the total mass multiply them
We need to change it to microgram, then multiply it by 10^-6
Put a decimal point at the end of the number and move it 6 places to the left to get the answer
