Answer:
(x) = 
Step-by-step explanation:
let y = h(x) and rearrange making x the subject, that is
y = 
x + 12 ( multiply through by 4 to clear the fraction )
4y = 3x + 48 ( subtract 48 from both sides )
4y - 48 = 3x ( divide both sides by 3 )
= x
Change y back into terms of x, thus
(x) =

Answer: 24 pistachios cupcakes.
Step-by-step explanation:
We know that:
They recently sold 6 pistachio cupcakes and 8 other cupcakes.
Then we can model this with the ratio 6:8
This means that for each 6 pistachio cupcakes sold, they also sell 8 of another type of cupcakes.
Whit this info, if they sell 56 cupcakes, how many of them will be pistachio cupcakes?
Using the ratio above, we must find a number N such that:
N*6 + N*8 = 56.
N*(6 + 8) = 56
N*14 = 56
N = 56/14 = 4.
This means that:
out of the 56 cupcakes, 4*6 = 24 are pistachios cupcakes
4*8 = 32 are other cupcakes.
Then you should expect that 24 out of the 56 cupcakes are pistachios cupcakes.
