Answer:
d. 24
Step-by-step explanation:
Let's solve your equation step by step
(3^2)(x)-5=81
step 1:simplify both sides of the equation
(3^2)(x)-5=81
simplify.
9x-5=81
step 2:Add 5 to both sides.
9x-5+5=81+5
9x=86
divide both sides by 9.
9x/9=86/9
x=86/9
Answer:86/9
Hope this helps!
Answer:
5/1 or just 5
Step-by-step explanation:
rigtht 15:3 as 15/3 and then cancel 15 and three (3x1=3 and 3x5=15)
Whatever% of anything, is just (whatever/100) * anything.
there were a total of 560000 votes, now, off those some are valid and some are invalid.
we know 15% of that are invalid, that simply means that 85% are valid, since 85% + 15% is the whole thing, or 100%, if 15% are not good, the other 85% are the good ones.
how many are the valid ones anyway? well, 85% of 560000, which is just (85/100) * 560000.
we know that off those valid ones, the candidate got 75% of those, so how much is 75% of that?
well, (75/100) * [ (85/100) * 560000 ].
Answer:
The answer would be A.
Step-by-step explanation:
This is because when you divde 120 by 10, you will be given an answer of 12. This shows that 10% of 120 is 12.
