a simple way to do away with denominators, is we can simply multiply both sides by the LCD, in this case the LCD is 3, so let's multiply both sides by 3.
Answer:
C and D
Step-by-step explanation:
5^3 - 5^0 = 125 - 1 = 124, so it's not A
5^12 / 5^4 = 5^(12-4) = 5^8, so it's not B
5^7 * 5^-4 = 5^(7+(-4)) = 5^3, so it can be C
5^0 * 5^3 = 5^(0+3) = 5^3, so it can be D
5 + 5^2 = 5 + 25 = 30, so it can't be E
Answer:
I'm not completely sure but if they want exponents for 6 * 6 * 6 then it should be 
Step-by-step explanation:
15/100*x=39
x=39*100/15
x= 260 is the total number of people who were asked
20 because of the whole is 40 and the shaded part is by 20 you just take half of 40 and you get 20
