You make a large bowl of salad to share with your friends. your brother eats 1/3 of it before they come over. you want to divide the leftover salad among 6 friends.

of the salad.

Step-by-step explanation:

You make a large bowl of salad to share with your friends.

Your brother eats   of it.

Now the leftover salad = 1 -  

                                      =  

                                      =  

You want to divide the leftover salad among 6 friends.

÷ 6

=   ×  

=  

=  

Each friend gets   of the salad.

yes ok                                            

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
