x = 1
Answer:
-15/2 =x
Step-by-step explanation:
12(x+5)=4x
Distribute
12x +60 = 4x
Subtract 12x from each side
12x-12x +60 = 4x-12x
60 = -8x
Divide each side by -8
60/-8 = -8x/-8
15/-2 = x
-15/2 =x
In 2014 , 2277 was 110% of 2013.
Number in 2013 = 90% of the year before (2012)
Let the number in 2013 be x. From the first statement,
2277 = 110% of x
2277 = (110/100)x
2277 = 1.10x
x = 2277/1.1 = 2070
Number in 2013 is 2070
Number in 2013 = 90% Number in 2012
2070 = (90/100) * Number in 2012
2070 = 0.90 * Number in 2012
2070 / 0.90 = Number in 2012
2300 = Number in 2012
Number in 2012 = 2300
