The total number of subsets that can be derived from the given set is given by the formula 2 n where n is the number of elements present in the set.Here in the given set n=3

Number of subsets = 2 3 = 8 subsets are formed.

Remember, the number of subsets of a set is 2 $2^n$ , where n is the number of elements in the set. Thus, it is 2³ = 8. If you want a proof for that, ask in comments below.

Answer:

4

Step-by-step explanation:

$3\frac{5}{9} * 4\frac{6}{10} = \frac{15}{9} *\frac{24}{10}$

$\frac{15}{9} *\frac{24}{10} = \frac{360}{90}$

$\frac{360}{90} =4$

One positive number is 5 times another number. The difference between the two is 1480.

Stella [2.4K]

Hey there!

Let's create a systems of equations with x and y to find our numbers.

x=5y

x-y=1480

Let's plug our x value into the second equation.

5y=y=1480

4y=1480

y=370

Now we multiply this number by five as the first equation says to get our x.

x=1850

Our numbers are 1850 and 370.

I hope this helps!
