A recipe calls for a total of 3 2/3 cup flour and sugar.if the recipe calls for 1/4 cups of sugar,how much flour does he need
viva [34]
You'll want to convert 3 2/3 into a common denominator with 1/4.
The nearest common denominator of 3 and 4 is 12. 
1/4 * 3/3 = 3/12
2/3 * 4/4 = 8/12
You need 3 and 8/12 in total so subtract 3/12 from 3 8/12 to get the flour
3 8/12 - 3/12 = 3 5/12.
You would need 3 5/12 cups of flour.

Answer:

  • adult: $7
  • student: $10

Step-by-step explanation:

Let a and s represent the prices of adult and student tickets, respectively.

  13a +12s = 211 . . . . . . ticket sales the first day

  5a +3s = 65 . . . . . . . ticket sales the second day

Subtracting the first equation from 4 times the second gives ...

  4(5a +3s) -(13a +12s) = 4(65) -(211)

  7a = 49 . . . . . . . simplify

  a = 7 . . . . . . . divide by 7

  5(7) +3s = 65 . . . . substitute into the second equation

  3s = 30 . . . . . . . subtract 35

  s = 10 . . . . . . . divide by 3

The price of one adult ticket is $7; the price of one student ticket is $10.
