Need help I’m in the middle of a test and if I fail this I’m probably getting hit when I get home thanks

5 toppings

Step-by-step explanation:

x = no. of topping

( 29.25 - 17.50 ) / 2.35 = x

x = 5

5

Step-by-step explanation:

To find out how many toppings there are subtract the base price from 29.25(29.25-17.50). Then divide the result by 2.35(11.75/2.35). You get 5.

5050

hope this !

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
