Answer:
0.23076923
Step-by-step explanation:
To express 3/13 as a decimal, we divide the the numerator by the denominator.
This will give us:
3:13
=0.23076923
simplifying the above we get: 0.230769...
The equation 2 has a graph which is a straight line.
Why?
We can know which of the given equations has a graph which is a straight line just checking the exponents of the variables.
We must remember that every variable that has an exponent equal or higher than 2 (quadratic) will not have a straight line as a graphic.
So, checking the exponents from the given equations, we have:

Hence, we can see that the only equation that has a linear term (straight line graph), is the second equation.
Have a nice day!
Note: I have attached a image for better understanding.
Answer:
6 m by 8 m
Step-by-step explanation:
The sum of two adjacent side lengths is half the perimeter, so is 14 meters. Two numbers differing by 2 that have a sum of 14 are half that total plus or minus have the difference: 7 ±1 = 6 and 8.
The room is 6 meters wide and 8 meters long.
This an { } solution because the absolute value is always a positive number unless there is a negative sign in front of the brackets.
hope this helps :)
