Answer:
1). 9 red 6 fancy 2). 50 shirts 20 pants 3). 62 purple 31 red 4). 19 dimes 9 quarters
Step-by-step explanation:
Most are systems of equations. So, they will have more than one equation.
1). x (Red wrapping paper) y (fancy print paper)
x + y = 15
2x + 4y = 42
Solved: x = 9 y = 6
2). x (shirts) y (pants)
x + y = 70
12x + 30y = 1200
Solved: x = 50 y = 20
3). x (purple) y (red)
I ended up dividing 93 by 3 and then multiplying it by 2 for purple and keeping the other third for red. Not quite sure how to fit this into an equation, its just simple math.
Solved: x = 62 y = 31
4). x (dimes) y (quarters)
.10x + .25y = 4.15
x = y - 10
Solved: x = 19 y = 9
Answer:
(-2,-1)

Answer:
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
