Answer:
Tiffany ate 4 slices of pizza
Step-by-step explanation:
1/4 of 16 is 4
Set up a proportion
EA / EB = ED/ EC
16 / (5x + 2 + 16) = 12 / (12 + 24)
16/(5x + 18) = 12 / 36 Cross multiply
16 * 36 = (4x + 18)*12 Remove the brackets
576 = 48x + 216 Subtract 216 from both sides.
360 = 48x Divide by 48
360/48 = x
7.5 = x
Option A.
is the correct radical form.
Step-by-step explanation:
Step 1:
The numerator of the exponential is kept where it is whereas when converting an exponential into a radical, the denominator becomes the root of the variable.
The numerator of the exponential is 2 while the denominator is 5.
Step 2:
So the numerator is kept where it is while the denominator, 5 becomes the root of the variable.
Out of the given options, options 2, 3 and 4 have square roots so they cannot be the answers. Option 1 has a root to the power of 5, so it is the correct radical form.
So option 1 is the right answer.
