If you mix 1 cup of chocolate chips and 1 cup of raisins what is the percentage of chocolate chips
algol13

Answer:

50%

Step-by-step explanation:

50% because when there is only 2 variables and they are each 1 cup there is an even amount of stuff and when you ask for only one percentage that would be 50% because everything is even. Even if you asked for the percentage for the cup of raisins it would also be 50%. Hope this helps <3

Can someone help me with this 2 step eqaution
Snowcat [4.5K]
The answer is:  " 40 books " .
____________________________________________
Explanation:
____________________________________________
Let "x" equal the number of books that Jill started with.  Solve for "x" :
____________________________________________
         x – (1/2)x  + 16 = 36 ;

1x – (1/2)) = (1/2)x ; 

(1/2)x + 16 = 36 ; 

Subtract "16" from EACH SIDE of the equation:

(1/2)x + 16 – 16 = 36 – 16  ; 

(1/2)x = 20 ; 

Multiply each side of the equation by "2" ; 

2*(1/2)x = 20 * 2 ; 

to get:  x = 40 . 
____________________________________________
The answer is:  " 40 books " .
