If you would like to know which is the correct unit of measurement to use when figuring out how many yards each child would run in the race, you can calculate this using the following steps:
80 yards * 2 + 60 yards * 2 = 160 + 120 = 280 yards
The correct measurement would be A. yards.
Answer:
81.25 miles.
Step-by-step explanation:
We divide 6.5 by 2 to get 3.25, we then multiply 3.25 by 25 to get our answer.
Answer:
$210
Step-by-step explanation:
The first thing we can do is to add the $25 back on to the total cost.
25 + 115 = 140.
We do this because he Sam used a gift certificate on the ski's that are already 2/3 of the original price.
Now, to find the original price we can use this equation:

X represents the original price.
To solve this equation you would flip 2/3 to 3/2 and multiply that by 140, as seen below:

Now you can solve:

We can check this answer by multiplying 210 by 2/3
(210)(2/3) = 140
Remember, Sam used a gift certificate for $25
140 - 25 = $115
Therefore, the original price of the skis is $210.
