Answer:

-0.34, -0.35, -0.36, -0.37

Step-by-step explanation:

A rational number can be any number, negative or positive, so long as if the decimals (if any) terminate at some point or at least repeats itself.

-\frac{2}{5} = -0.4

-\frac{1}{3} = -0.333_ (This means that the digit "3" is repeated forever)

Thus, the possible rational numbers can be:

-0.34

-0.35

-0.36

-0.37

-0.38

-0.39

You can even write decimals like -0.334 since it is bigger than -0.333_ but smaller than -0.4.

I.) (5x+3)/4-(2x-4)/3=5
Clear fractions:
3·((5x+3)/4)=15x+9
4·((2x-4)/3)=8x-16
15x+9-(8x-16)=5
15x+9-8x+16=5
Combine like terms:
7x+25=5
7x=-20
x=-20/7

II.) (3/11)·(5/6)-(9/12)·(4/3)+(5/13)·(6/15)
Remember PEMDAS
So first multiply:
3/11·5/6=15/66
9/12·4/3=3/3·1/1=3/3=1
5/13·6/15=1/13·6/3=6/39=2/13
(15/66)-1+(2/13)
Combine:
15/66-1/1=15/66-66/66=-51/66
-51/66+2/3=-51/66+44/66=-7/66
Answer: -7/66 :)

Please Help! 10 points!
Tcecarenko [31]

we just need add x next to ratio and sum them all to get perimeter

9 + x + 2x + 4x = 65

7x = 56

x = 8

well since 8(x)<9<16(2x)<(32(4x), then

the shortest side is 8
