Answer:

4^(11/20)

Step-by-step explanation:

The applicable rule of exponents is ...

(a^b)/(a^c) = a^(b-c)

Using that here, we have ...

4^(3/4)/4^(1/5) = 4^(3/4 -1/5)

= 4^(15/20 -4/20) = 4^(11/20)

Each of the three oldest children sleeps in a twin bed. They all need bed sheets. A brand of sheets is on sale for “Buy one get

kow [346]

Answer:

Step-by-step explanation:

Two sheets will cost: $27

The value of the first sheet will be $18, and since the other sheet is half off it will be half of the original value: 18 * 0.5 = 9.

Then you add the values together: 18 + 9 = 27.

Six sheets will cost: $81

For every sheet that is the original value there is a sheet that is half off. So since there are six sheets, 3 of the sheets will be $18 and three of them will be $9. We already know that 18+9=27, so just multiply that value by 3.

27*3= 81

Better deal: The second example

In the second example sheets are 30% off. 30% of 18 is $6. Subtract that value from 18 and you will get $12. In the second example one sheet is $12.

If we multiply that value by 2, we will get $24.

In the first example, two sheets costs $27, while in the second example two sheets cost $24. Since the cost is less for the second example, the second example is the better deal.

Answer:

I could do 1 and 3

1) 2x-3y=-2 ....1

2x+y=14......2

=-4y=-16

y=4

Substitute (y=4) into equation 1

2x-3 (4)=-2

2x-12=-2

2x=-2+12

2x=10

×=5

3) 5x+5y=20....1

-3x+5y=4......2

=8x=16

x=2

Substitute (x=2) into equation 1

5 (2)+5y=20

10+5y=20

5y=20-10

5y=10

y=2
