Answer:
3.142
Step-by-step explanation:
sorry if im wrong.
The given expression is
First, we use the distributive property to get rid of the parenthesis.
Now, we sum 2x on each side
As you can observe, the variables were eliminated and the resulting equation is true. This means the equation has infinite solutions.
Number of unburnt cells, x= 151.9 x 10^10
<u>Step-by-step explanation</u>:
Number of unburnt cells= x
x = ?
<u>Given</u>: 2% cells are burnt
(3.1 x 10^10 cells)/2% = x/98%
x = (3.1 x 10^10)(98%/2%)
=(31000000000)(49)
x =151.9 x 10^10
y+1=3(x-4)
Multiply the bracket by 3
y+1=3x-12
Follow y=mx+b Move +1 to the other side. Sign changes from +1 to -1
y+1-1=3x-12-1
y=3x-13
Slope=m = 3
b= y-intercept=-13
Answer: Slope=m=3- D.
