30 = 60% of x
x being our variable, we need to figure out what x equals. Use the formula I put in the attachment. Multiply 30 by 60, and then divide the product by 100. That will give you the answer :)
Answer:
the answer is option D. 25 units. I hope that you'd understand
23 is a whole number 75 is the numerator and use 100 as the denominator since 75 is in the 100nths place.
-(-2)^4 = 16
The - sign multiplies inside the bracket to a positive, 2^4 = 16
