The answer is 2 because distributive property means that you can multiply with the numbers inside of the parentheses and still get the same answer
Do the same process for each of the 3
you have miles per how many minutes and you need miles per hour
you know 60 minutes make 1 hour convert the minutes to hours
this will gives you miles per equivalent hour
you need miles per 1 hour
Here is number 1
1) 5 miles in 20 minutes
5 miles in (20/60) hr = 5 miles in 1/3 hr
to get 1 hr multiply by 3
equation so keep the balance
5 * 3 = 15
rate = 15 miles per hour.
same process for the others
here's the solution,
let the length of shorter peice = x
then the lenght of longer peice = 6x + 8
now, we know that the sum of length of peices measures 99 feet,
So,
=》x + 6x + 8 = 99
=》7x = 91
=》x = 13
shorter piece length = 13 feet
longer peice length = 13 × 6 + 8 = 78 + 8 = 86 feet
The first digit is 9 or 8.
The fifth odd number you count beginning with one is 9.
Let the middle number be x.
If the first number is 8, then 8 + x + 9 = 22 => 17 + x = 22 => x = 22 - 17 = 5. then the number is 859 which approximates to 900 to to the nearest hundred.
If the number is 9, then 9 + x + 9 = 22 => 18 + x = 22 => x = 22 - 18 = 4, then the number is 949, which also approximates to 900 to the nearest hundred.
Therefore, the required number is 859 or 949.
