what is the value of the rational expression below when x is equal to three?
17+x/x+2
just plug in 3 for x:
(17+3)/(3+2) = 20/5 = 4
what is 5t=16
To find the value of the rational expression 17 + x / (x + 2) when x is equal to three, substitute the value of x into the expression and simplify.
First, substitute x = 3 into the expression:
17 + (3) / (3 + 2)
Now, solve the expression:
17 + 3 / 5
Next, perform the addition:
17 + (3/5)
To simplify further, you need to have a common denominator for the addition:
(85/5) + (3/5)
Combine the numerators:
(85 + 3) / 5
Finally, add the numerators:
88 / 5
So, the value of the rational expression when x is equal to three is 88/5 or 17.6.
To find the value of the rational expression when x is equal to three, we substitute x = 3 into the expression and simplify.
Let's substitute x = 3 into the expression:
17 + 3 / 3 + 2
Next, we simplify the numerator and the denominator:
Numerator: 17 + 3 = 20
Denominator: 3 + 2 = 5
Now, we divide the numerator by the denominator:
20 / 5 = 4
Therefore, the value of the rational expression 17 + x / x + 2 when x is equal to three is 4.
