Answer:

To verify your final answer:

x = 4.75

2x = 9.5

x+6 = 10.75

Step-by-step explanation:

Let X = the length of the shortest side

Then the longest side is X + 6 and the other side is 2X.

The sum of all sides equals the perimeter which equals 25.

So add them up, set it equal to 25 and solve for X.

X+6+x+2x=25, x being the smallest side

8/x=14/7 what does x equal

Veronika [31]

Answer:

when you have two fractions that equal each other you want to solve by using cross multiply

What cross multiply is, is when you multiply diagonally so:

8/x=14/7

you would take 14*x and 8*7

14x=56 (you would then divide each side by 14)

x=4 (14/14=1, 56/14=4)

8/4=14/7

To check your work you could simplify

8/4=2

14/7=2

2=2, which is true

x=4

Hope this helps ;)
