i'm trying to do a table of values for
9x/5-4/5
if I use 4, my answer is
36/5-4/5
7.25-4/5 = 3.25/5 or .65
is this correct, if not what am I doing wrong?
That doesn't look right.
First, 36/5 = 7.2 (not 7.25)
Secondly, you should do all multiplication first, then do subtraction.
9*4/5 - 4/5
7.2 - 0.8 = 6.4
thanks. i'll pay closer attention to what i'm doing.
To determine if your calculation is correct, let's evaluate the expression step by step.
The expression you have is:
(9x/5) - (4/5)
If you substitute x with 4, you get:
(9 * 4/5) - (4/5)
First, let's simplify the fractions by multiplying the numerators and denominators:
(36/5) - (4/5)
Since both fractions have a common denominator 5, you can subtract the numerators directly:
(36 - 4) / 5
Simplifying further:
32/5
So, when x is 4, the value of the expression (9x/5) - (4/5) is 32/5, or equivalently, 6.4.
Therefore, your answer should be 32/5 or 6.4, rather than 3.25/5 or 0.65.
It seems you made a small error during the calculation. Make sure to accurately perform the arithmetic operations to obtain the correct result.
