Mathematics
1 answer:
Fofino [41]2 years ago
8 0

Answer:

2

Step-by-step explanation:

4x+3−x=12x−15

<u>Combine 4x and −x to get 3x</u>.

3x+3=12x−15

<u>Subtract 12x from both sides</u>.

3x+3−12x=−15

<u>Combine 3x and −12x to get −9x</u>.

−9x+3=−15

<u>Subtract 3 from both sides</u>.

−9x=−15−3

<u>Subtract 3 from −15 to get −18</u>.

−9x=−18

<u>Divide both sides by −9.</u>

x= –18÷–9

<u>Divide −18 by −9 to get 2.</u>

x=2

The diameter of a human red blood cell is 0.000009 m. The diameter of a cold virus is 0.00000003 m Approximately how many times
krek1111 [17]

Answer:

D. 3*10^2

Step-by-step explanation:

Given the diameter of human red blood cell =  0.000009 m

diameter of a cold virus = 0.00000003 m

To know how many times as large is the diameter of a red blood cell as the diameter of a cold virus, we will take the ratio of the diameter of human red blood cell to that of a cold virus as shown;

diameter of human red blood cell/diameter of a cold virus = 0.000009 m/0.00000003 m

= 9*10^-6/3*10^-8

= 9/3 * 10^-6-(-8)

= 3 * 10^(-6+8)

= 3*10^2

Hence the diameter of a red blood cell is 3*10^2 larger than that of the cold virus

An=−5n+90 i dont know it
olga2289 [7]
I am guessing your problem should read...

A)  n = -5n + 90    (isolate the variables by adding 5n to each side)
   +5n  +5n
   6n = 90        (since we don't want to know what 6n's are worth, divide by 6)
6n/6 = 90/6
   n = 15
