Answer:

13 1/3, 22 2/5

Step-by-step explanation:

It'll be easier if you put both of the mixed fractions into improper fractions, so:

1 2/3 ---> 3 x 1 +2 = 5 ---> 5/3

3 1/5 ---> 5 x 3 +1 = 16 ---> 16/5

Now if you want to write it down, but 8/1 to make it easier to work out.

8/1 x 5/3 = 8 x 5/3 x 1 = 40/3 or 13 1/3

7/1 x 16/5 = 7 x 16/1 x 5 = 112/5 or 22 2/5

I can get more descriptive, but this is the layout. Hopefully this makes sense.

laila [671]
So the first one is (7x)^(1/2) or square root of 7x minus - 5 square root all squared so

([7x^(1/2)]-[5^(1/2)]) times ([7x^(1/2)]-[5^(1/2)])

or 7x-(35x^(1/2))-5+(35x^(1/2)) or 7x-5

number 2
since 11 is 1/2 of 22 it can be written as 

the square root of 3 or 3^(1/2)

bearhunter [10]

Answer:

All are rational.

Step-by-step explanation:

1)

=1/3/3/5

=1/3×5/3

=5/9

5/9 is non-terminating and recurring number so it is rational.

2)

4/3√9/5

=4/3*3/5

=4/5

4/5 is a terminating number it is rational.

3)

2*√16/√4

=2*4/2

=4

4 is a natural/whole number it is also rational.

PLEASE HELP 50 POINTS
prohojiy [21]

Answer:

12 sales

Step-by-step explanation:

Let x represent the number of sales each man had.

For Salesman A, he earns $65 per sale; this is 65x.

For Salesman B, he earns $40 per sale; this is 40x.  We also add to this his weekly salary of $300; this gives us 40x+300.

Since their pay was equal, set the two expressions equal:

65x = 40x+300

Subtract 40x from each side:

65x-40x = 40x+300-40x

25x = 300

Divide both sides by 25:

25x/25 = 300/25

x = 12
