Answer:
A. 201.6 = 11.2f
Step-by-step explanation:
we solve for each unknown to verify which equality will require the division property:
#A. 201.6 = 11.2f
Hence, division property used.
#B. 35.4=Z ÷ 3.1
Hence, multiplication property used.
#C. t/3.2=15.1
Hence, multiplication property used.
#D. 201.6 = 11.2+c
Hence, subtractionproperty used.
Practice is key in mathematics! Always search up the topic and re-read the lessons with some practice problems to see if you got it. Asking your teacher and peers to help is another way to go.
Remember, your teacher had to learn this in order to teach you about it!
Answer:
it should be number A hope that helps
If some set A has n elements, then it has 2^n subsets.
Using that, the sentence, "The total number of subsets of ‘m’ is 56 more than the total number of subsets of ‘n’." gives you the equation 2^m - 2^n = 56
Factor both sides: 2^n * (2^(m-n) - 1) = 2^3 * 7
Since 2^n is a power of 2 and (2^(m-n) - 1) is an odd integer, we must have 2^n = 2^3 2^(m-n) - 1 = 7
Solving these, you get n = 3 and m = 6.
