50 hamburgers and 200 hotdogs

120 hamburgers and 180 hotdogs

100 hamburgers and 180 hotdogs

i think the answer is 120 hamburgers and 180 hotdogs ,but i'm not sure. to whoever me .

120 hamburgers and 180 hotdogs

Step-by-step explanation:

Let 'x' be the number of hamburgers and 'y' be the number of hotdogs sold.

Then, the total number of hamburgers and hotdogs sold on friday will be given by :_

On the basis of their cost, the total cost will be:-

Subtract (1) from (2), we get

Substitute the value of x in  (1), we get

Hence, they sold 120 hamburgers and 180 hotdogs.

answer: apothems is your answer

step-by-step explanation: hope u get it right

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
