Answer:

41 miles

Step-by-step explanation:

The first week, which is 7 days, Adam walked 2 miles a day. So, we have the multiplication equation: 2 * 7 = 14 miles.

For the next 9 days, Adam walked 3 miles per day. So, we have the multiplication equation: 3 * 9 = 27 miles.

Now, we just add these two values together:

14 + 27 = 41 miles

Thus, the answer is 41 miles.

Hope this helps!

If car can travel 50 miles in 55 minutes, how long will it take to travel 75 miles ?
mrs_skeptik [129]
First of all, if you are traveling more, then you will have to take more time to get there. So since the answer A is less than the original number 50 you can rule that choice out. Now to solve, you will put 50 over 55 such as this 50/55. This represents miles/minutes. So next you will put 75/x since we are trying to solve for x (minutes). Now our problem looks like this 50/55 times 75/x. To solve the answer you will need to cross multiply. You will multiply 75 and 55 together to get 4,125. (This will be your numerator, or top number) Next you will multiply 50 and x, this gives you 50. (This will be your denominator, or bottom number. Now you have 4,125/50. Divide your two numbers and you get 82.5! The answer is D. 82.5! Hope I helped!

Part A) First, you need to find out how much she makes each hour.40/5 = 8 & 48/6 = 8 ... This shows that she makes $8 an hour 

To find the first missing number, you will do 8 * 8 = 64 ... This shows that she makes $64 in 8 hours.

To find the second missing number, you will do 56/8 = 7 ... This shows that she makes $56 in 7 hours.

Part B) Barb makes $9 every hour. To find the amount of money she earns for 5, 6, and 8 hours of work you will need to multiply $9 by the amount of hours she worked.

9 * 5 = 45 ... This shows that she makes $45 in 5 hours.

9 * 6 = 54 ... This shows that she makes $54 in 6 hours.

9 * 8 = 72 ... This shows that she makes $72 in 8 hours.

Part C) In part B, you found out how much she makes after working at the theme park for 5 hours. ($45 in 5 hours)

Next, you'll need to find out how much she makes after mowing lawns for 5 hours.
5*8 = $40 ... This shows that she makes $40 in 8 hours

Now you need to the difference. 45 - 40 = 5 ... She makes 5 more dollars working at the theme park for 5 hours than mowing lawns for 5 hours.
