Solve for y.
6y-1.5x=8
Answers
Answer: Y = 0.25x + 4/3
Step-by-step explanation:
Step 1: Add 1.5 to both sides
-1.5x + 6 + 1.5x = 8 + 1.5x
6y = 1.5x + 8
Step 2: Divide both sides by 6
6y/6 = 1.5x + 8/6
Y = 0.25x + 4/3

Regina travels ½ of a kilometer for every ¼ of a minute she drives. You were told that the trip from Times Square to Pelham Parkway is 72 kilometers. How many minutes would her trip have taken by car?
Answers
Answer:
36 minutes.
Step-by-step explanation:
The best way to solve this is to find how much distance is traveled in a minute and then divide the total distance by the distance traveled in a minute. Now let's apply.
1/4 x 4 = 1 minute, so in this problem, 1/2 x 4 = 1 minute.
1/2 x 4 = 2.
72 / 2 = 36.
Her trip would have taken 36 minutes by car.
Answer:
36 minutes.
Step-by-step explanation:
For every mile she takes it's 1/2 of a minute. Then just do 72/2 and get 36 :)

Jayden used a Groupon at the local pizza shop. Instead of paying $15, for the pizza, he paid $12.
Haley and Arianna agree that the percent of decrease is 20% but their explanations differ. Haley says to find the 20%, you have to determine what percent of 15 is 12. Arianna thinks you have to determine what percent of 15 is 3. Who is correct? Explain your thinking.
Answers
Answer:
She is correct because they need to find how much is the discounted price, which is 3. So to see what percentage it is, they need to see how much 3 is worth in comparison to 15. If we spilt 15 into 5 parts to make every part worth 20%, the answer would be 3. Thus Arianna is correct.
