Answer:
270 Markers
Step-by-step explanation:
5 x 54 = 270
(sorry if I'm wrong)
First of all you times 2.16.... by 100 to get 21.61616.....
you then minus the original number to get 21.4.
You can then times that by 10 to why 214 and you can divide 214 by 99:
214/99 = 2.161616
Hope this helps! :)
Answer:
Step-by-step explanation:
decrease=400×0.285=114.000 $
amount at the end=400-114=286 $
If 20 is 50% of a number it is just going to be 20 times 2... so it is 40
x^2 =144 has 2 solutions
x=sqrt(144)
x=+-12
x= 12 and x=-12
12*12 = 144 and (-12) * (-12) = 144
a square root has 1 positive and 1 negative solution
x^3 = 27
(x^3)^(1/3)=(27)^(1/3) ^(1/3) is the cube root
x = 3
it only has one solution because a negative * a negative * a negative would be negative
