Question 67 and 68 . or one or the other.

question 67-the answer is Rory has eaten 1 1/4 of all the chocolate he has been given.

question 68-answer A-30 degrees

Step-by-step explanation:

question 67:

first Rory ate 1/2 of his chocolate

then, his sister gave him another whole chocolate bar an hour later.

that is 1/2+1=1 1/2--3/2/2=3/4

add 3/4 and 1/2--3/4 1/2~2/4--2/4+3/4=5/4 or 1 1/4

so the answer is 1 1/4

question 68:

if you draw a base to connect the last side of the angle into a triangle, you find that all three sides are equal, making the triangle an equilateral triangle.  An equilateral triangle's angles all equal 30 degrees.

so, the answer is answer A: 30 degrees

x = 17

step-by-step explanation:

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17
