Step-by-step explanation:
let G be the number of grand croisssants, and P the number of petit croissants :
we have that 1 ounce of flour and 2 ounces of butter result in one G.
additionally, we have that 1/4 ounce of flour and 1/3 ounce of butter result in one P.
Ralph has 4 ounces of flour and 6 ounces of butter, If he bakes more than 1 G then he will never use all of his ingredients!, let's see:
1 G:
he now has 3 ounces of flour, and 4 ounces of butter,
now we need to figure out how many P's we would obtain with such amounts:
let x be the number of P's
which is reasonable, Ralph can bake 12 P's,
now with more than 1 G:
2G:
Ralph has now 2 ounces of flour and 2 ounces of butter, now we have to figure out that x is the same using the remaining ingredients
This is impossible.
3G:
he runs out of butter.
There is the answer, he is able to bake 1 grand croissant and 12 petit croissants
Equivalent expressions are expressions that have the same values.
The expression is and the number is 12
Represent the number with x.
So, the sum of a number (x) and 7 would be represented as: x + 7
Three times the sum would be represented as: 3(x + 7)
This expression is equivalent to 57.
So, we have:
Divide both sides of the equation by 57
Subtract 7 from both sides of the equation
Hence, the number is 12
