ich was 90% of the number from the year before. How many student athletes signed up for a spring sport in 2012.
1 answer:
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

Answer:
x=5/13
Step-by-step explanation:
2/3+7/2=9x+5/6+4x
2/3+7/2-5/6=9x+4x
lcm of 2,3,6=6
2/3=4/6 7/2=21/6 5/6=5/6
4/6+21/6-5/6=9x+4x
30/6=13x
5=13x
x=5/13

Answer:
5x - 6y +36 =0 is the required equation.
Step-by-step explanation:
(x1, y1) =(-8, - 1)
Slope (m) =5/6
The equation is:
(y - y1) =m(x-x1)
y +1=5/6(x +8)
6y +6 =5x +40
5x - 6y +36 =0 is the required equation.
Hope this helps!!!!
