Chuck and Blaire decided to share a 10 ounce bag of candy. They ate of the
bag. How many ounces of candy did
they eat?

Pls help me!

A. 7 1/6

Step-by-step explanation:

10 3/4 * 2/3=

43/4 * 2/3= 86/12

86/12 = 7 2/12 = 7 1/6

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
