If the number is 200 more than 355, then your number is 555.
How did I get that?
355 + 200 = 555
Step-by-step explanation:
To find the perimeter of something, we add all of the measurements of the sides together.
A rectangle has 4 sides, this means we must double the algebraic hints given to us.
If we add them all up together it will look like this:
x-9+x-9+3x-4+3x-4=138
If we simplify it by collecting the like terms:
8x-26=138
We add 26 onto 138
8x=164
To find out what x equals, we divide by 8:
164÷8= 20.5
Answer:
x=20.5cm
x-9 is 11.5
3x-4 is 57.5
I know that you will not give 100 points but just wanted to help.
Hi there!
(32 + 60) ÷ 135 = x
92 ÷ 135 = x
0.6814814... = x → 814 is periodic, so it just keeps repeting itself.
There you go! I really hope this helped, if there's anything just let me know! :)
