Answer:
2:8 is the ratio to an equal ratio
Answer:
40,000
Step-by-step explanation:
You want to start with the exponent and then multiply afterward in both of the equations.
8 x 10^-2:
10^-2 = 0.01
0.01 x 8 = 0.08
2 x 10^-6:
10^-6 = 0.000001
0.000001 x 2 = 0.000002
Obviously, you can see the relationship between 8 and 2 in the division. Now, you just divide 0.08 by 0.000002 and you get 40,000.
Answer:
B. $54
Step-by-step explanation:
PEMDAS: Do multiplication and division first
65 - (2*7=14) + (9/3=3)
65-14+3
Go from left to right and solve
51+3=54
Answer:
Step-by-step explanation:
![8x + c = k\\\\8x + c-c = k -c \ \ \ \ \ \ \ \ \ [\ subtract \ c \ from \ both \ sides \ ]\\\\8x = k - c\\\\\frac{8x}{8} = \frac{k-c}{8} \ \ \ \ \ [ \ divide \ both \ sides\ by\ 8 \ ]\\\\x = \frac{k-c}{8}](https://tex.z-dn.net/?f=8x%20%2B%20c%20%3D%20k%5C%5C%5C%5C8x%20%2B%20c-c%20%3D%20k%20-c%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5B%5C%20subtract%20%5C%20c%20%5C%20from%20%5C%20both%20%5C%20sides%20%5C%20%5D%5C%5C%5C%5C8x%20%3D%20k%20-%20c%5C%5C%5C%5C%5Cfrac%7B8x%7D%7B8%7D%20%3D%20%5Cfrac%7Bk-c%7D%7B8%7D%20%5C%20%5C%20%5C%20%5C%20%5C%20%5B%20%5C%20divide%20%5C%20both%20%5C%20sides%5C%20%20by%5C%20%208%20%5C%20%5D%5C%5C%5C%5Cx%20%3D%20%5Cfrac%7Bk-c%7D%7B8%7D)
