Step-by-step explanation:
4) 24/30=4/5
5) 2/24=1/12
6)14/84=1/6
7) 20/45=4/9
8)7/49=1/7
Answer:
The 3rd one as it's cubic
With 5 elements in A={20,1,6,10,11}, there are 2^5=32 possible subsets, including
the null set, and A itself.
Any subset that is identical to A is NOT a proper subset.
Therefore there are 31 proper subsets, plus the subset {20,1,6,10,11}.
The subsets are:
null set {} (has no elements) ........total 1
{20},{1},{6},{10},{11}.......................total 5
{20,1},{20,6}...{10,11}.....................total 10
{20,1,6},{20,1,10},...{6,10,11}.........total 10
{20,1,6,10}...{1,6,10,11}.................total 5
{20,1,6,10,11}.................................total 1
Altogether 32 subsets.
Answer:
16.3
Step-by-step explanation:
The tenth place is right after the decimal, afterwards, its hundredths and then thousandths. The number after the tenth's place is 8. Since the number is 5 and above, you round up and add 1 to the tenths place to get 16.3. If the hundredths was 4 and below it would round to 2.

Answer:
x = 5/4
Step-by-step explanation:
5x - 6 = 4 - 3x
8x - 6 = 4
8x = 10
x = 5/4
The error is that -3x is moved across the = in an incorrect manner. You instead need to add the 3x across the = ending up with 5/4. Adding this across negates the negative which makes it 8x, the rest of the step are as follows.
