So convert to 20ths
9/10 is 18/20 ...................1/4 is 5/20
Now add, since the denominators are the same
18/20 from 5/20 is -13/20 and that's the value of x
The perimeter is adding 2 sides lengthwise and 2 sides width and area is multipying one length by one width
The median average is the middle number in a set of numbers. So if you have a set of numbers and want to find the median, just write them down in order and the number in the middle is your answer. (If you have an even amount of numbers you should take the mean average of the middle two numbers, since there is no one middle number.)
2.4x = 14.4 so 2.4x/2.4 = 14.4/2.4 so x = 14.4/2.4
x + .9 = .25 so x + .9 - .9 = .25 - .9 so x = -0.65
The perimeter is the sum of the lengths of all of the edges of a shape, and the area is the amount of space in between, which is calculated differently for different shapes.
A median is the middle number.
2.4x= 14.4
2.4x/2.4= 14.4/2.4
x= 6 (Here the / is dividing not a fraction!)
x+9/10=1/4
x=1/4-9/10
x= (Do it on your calculator)
Perimeter= Add up all the sides!
Area= Multiply the base (Bottom) and the height! If its for a triangle, do that and divide by 2!
Hope I Helped!
