grams of Sean made a snack for himself and his friends using 4 slices of multigrain bread and 6 tablespoons of peanut butter. He cut the sandwiches into 8 equal pieces. Each of the 8 pieces had carbohydrates from the peanut butter. Each of the 8 pieces had grams of carbohydrates from the multigrain bread.

(Forgive me for the late answer) Have a good day! :D

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60

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
