Vlad [161]

Answer:

z^ {8/5}

Step-by-step explanation:

(z^{\frac{-4}{3})^{\frac{-6}{5} } \\We\ know\ that\ a^{(b)^c} = a^{bc}\\\\Hence, \\\\{z^{\frac{-4}{3})^{\frac{-6}{5}}\\}={z^{\frac{-4}{3}*\frac{-6}{5}\\}\\=z^{\frac{24}{15}}\\=z^\frac{8}{5}

A store is having a sale on jelly beans and almonds. For 6 pounds of jelly beans and 2 pounds of almonds, the total cost is $12
CaHeK987 [17]

Solution:

Let each pond of  jelly beans cost $x.

and each pond of almonds cost $y.

Then we can write

6x+2y=12.......(i)

3x+5y=15.....(ii)

Now solve these two equations together using substitution we get

3x=15-5y

30-10y+2y=12\\&#10;\\&#10;-8y=12-30\\&#10;\\&#10;-8y=-18\\&#10;\\&#10;y=2.25\\&#10;\\&#10;3x=15-5y=15-5*2.25=3.75\\&#10;\\&#10;x=1.25

Hence each pond of jelly bean cost 1.25$

Each pond of almond costs 2.25$

Tickets to a football game cost 5$ for students and 7$ for adults. write and solve a system of equations to determine the number
stepan [7]

Answer:

x + y = 680

5x + 7y = 3914

Step-by-step explanation:

Let the amount of students who purchased tickets equal x.

Let the amount of adults who purchased tickets equal y.

If you add the amount of adults and students, you get the total amount of people:

x + y = 680

Also, to find the amount students spent on tickets, you multiply the ticket price by the amount of students to get 5x. And to find the amount adults spent on tickets, you multiply the ticket price by the amount of adults to get 7y. By adding the two amount, you get the total amount of money:

5x + 7y = 3914

These are the two equations:

x + y = 680

5x + 7y = 3914
