Answer:
Top left Equation: 
Step-by-step explanation:
You start at 2/3, or the left side.
Since the line is directing left, you are subtracting, or adding a negative.
If you see, you are moving 7 - 1/3s to the left
7 x 1/3 = 7 / 3
7 / 3 = 2 1/3
And 2/3 + (-2 1/3) = -1 2/3

Answer:
r=5
Step-by-step explanation:
r+2=7
r=5
Ok so for number 5, AB is proportional to BC just like PQ is proportional to QR. AB = 9, BC = 15, PQ = 3, and QR = x. 9/15 = 3/x. Cross Multiply: This gives you - 9x = 45. Divide both sides by 9, and you get x = 5. QR = 5
