Pla may i have help i have done a but i carnt do b

A. Simon needs 125 ml of milk to make 4 pancake.  B. He needs 7 and a half grams of butter to make 12 pancakes

Step-by-step explanation:

A) If we know that 250 ml milk can help make 8 pancakes then we could set up a proportion as to how many milk we need to make 4 pancakes.

    Solve by cross  product,

8x = 1000

x = 125  

B) The same with this we could also set up a proportion. We know you need 5 grams of butter when making 8 pancakes.

   solve by cross product

60 = 8x

x = 7.5

answer: i can’t tell you that

step-by-step explanation:

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
