The units (-3,-1) and (-0,-0) are the following units located at (-4,-2).
You need to simplify it
lets start with your orgininal equation here:
-5+3x=10
Now lets try and get "x" alone. we will do this by adding 5 to both sides.
-5+3x=10
+5 +5
3x=15
Now we have 3 times "x" equals 15
The next step would be to divide both sides by 3 in order to get "x" alone.
3x=15
x=15/3
x=5
Answer:
bting it closer i can't see the top row sorry
Step-by-step explanation:
No, they are not equivalent
-41/2 would be division because the fraction would indicate that. you would be dividing -41 by 2. this would get you -20 1/2.
(-4)1/2 would be multiplying because of the parentheses. you would be doing -4 x 1/2 and that would get you -2.
hope this helps
First you need to find the area of the plate.
The formula for the area of a circle is Area = pi *r^2
The radius (r) is given as 6 inches.
We will use 3.14 for pi
Area = 3.14 x 6^2
Area = 3.14 x 36
Area = 113.04 square inches.
Now to find the density, divide the total bacteria by the area:
Density = 120,000 / 113.04 = 1061.57 which rounds up to 1,062 bacteria/ square inch.
