Sean is planning on running a half marathon in 3 months or 12 weeks. He wants to be able to break 2 hours or 120 minutes. Right now he can run 3 miles in 29 minutes. If he is able to maintain this pace, will he reach his goal? If he is able to decrease his average 3 mile pace by 1 minute each month or every 4 weeks, will he reach his goal? Finally, Sean is starting to feel good about his progress and starts wondering what kind of pace it would take to break 1 hour and 50 minutes?

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
