Rational numbers can be written as a fraction
Answer:
x = -1
Step-by-step explanation:
Solve for x:
12 = 24 - 4 (-6 x - 3)
-4 (-6 x - 3) = 24 x + 12:
12 = 24 x + 12 + 24
Grouping like terms, 24 x + 12 + 24 = 24 x + (12 + 24):
12 = 24 x + (12 + 24)
12 + 24 = 36:
12 = 24 x + 36
12 = 24 x + 36 is equivalent to 24 x + 36 = 12:
24 x + 36 = 12
Subtract 36 from both sides:
24 x + (36 - 36) = 12 - 36
36 - 36 = 0:
24 x = 12 - 36
12 - 36 = -24:
24 x = -24
Divide both sides of 24 x = -24 by 24:
(24 x)/24 = (-24)/24
24/24 = 1:
x = (-24)/24
The gcd of -24 and 24 is 24, so (-24)/24 = (24 (-1))/(24×1) = 24/24×-1 = -1:
Answer: x = -1
Answer:
Decrease by 20%.
Step-by-step explanation:
We have to find the percent of increase or decrease from n to 
.
Now, 
So there is a decrease fro n to .
Now, the percentage of decrease will be given by
= ![[ \frac{\textrm {Original Value - Final Value}}{\textrm {Original Value}}]\times 100 \%](https://tex.z-dn.net/?f=%5B%20%5Cfrac%7B%5Ctextrm%20%7BOriginal%20Value%20-%20Final%20Value%7D%7D%7B%5Ctextrm%20%7BOriginal%20Value%7D%7D%5D%5Ctimes%20100%20%5C%25)
= ![[ \frac{n - 0.8n}{n}]\times 100 \%](https://tex.z-dn.net/?f=%5B%20%5Cfrac%7Bn%20-%200.8n%7D%7Bn%7D%5D%5Ctimes%20100%20%5C%25)
= 20% (Answer)
