This is an algebra two honors question:
a jeweler has 12 grams of an 80% gold alloy that she wants to strengthen to 92.5%. write the rational function, p(x), which is the percent of gold in the alloy by mass where x is the number of grams of gold added.
a) write the rational function p(x). use these three expressions to write your rational expression: (12+x), 100x, and 12(80).
b) graph the function for the domain 0
c) use your function an find out how much gold the jeweler must add to create a 92.5% alloy.

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

step-by-step explanation:

half of the nubers are odd numbers (1,3,5) which in that case if you would be told to simplify it would be 1/2
