Simplify:
-225 / 15 - 7^2
/
6(-4)-3(-8) =
-225 / 15 -49 / -24 - 24 =
-15 - 49 / -48 =
-64 / -48 =
1 1/3 = 4/3
Is this correct?
TILT !!!!
You have
6(-4)-3(-8)
which is -24 + 24 = 0
because -3 * -8 = POSITIVE 24
ZERO in the denominator !
undefined
the top of the problem is
-225/15-7^2
which is then divided by
6(-4)-3(-8)
Yes, exactly
and
6(-4) = -24
-3(-8)= +24
-24 + 24 = ZERO !!!
It does not matter what the numerator is. if the denominator is zero, the answer is "undefined".
thank you
To simplify the given expression, let's break it down step by step:
First, we evaluate -225 / 15:
Dividing -225 by 15 gives us -15.
Next, we simplify 7^2:
7^2 is equal to 49.
Now, let's simplify the expression 6(-4) - 3(-8):
Multiplying 6 by -4 results in -24.
Multiplying 3 by -8 gives us -24 as well.
So, we have:
-225 / 15 - 49 / -24 - 24
Now, let's perform the operations in the order of operations (PEMDAS/BODMAS):
First, we divide -225 by 15, which gives us -15:
-15 - 49 / -24 - 24
Next, we simplify 49 / -24:
Dividing 49 by -24 gives us -2.0416 (rounded to four decimal places).
Now, we substitute these values back into the expression:
-15 - (-2.0416) - 24
To subtract a negative number, we can change it to addition:
-15 + 2.0416 - 24
Now, we combine the like terms (-15 and -24):
-39 + 2.0416
Next, we add -39 and 2.0416:
-36.9584
So the simplified expression is approximately -36.9584.
To verify if your answer of 1 1/3 (or 4/3) is correct, we can simplify further:
-36.9584 as a fraction is -36 479/625.
Since -36 479/625 does not equal 4/3, the simplified answer you provided is incorrect.
