Answer:
21u-26
Step-by-step explanation:
add all the side lengths together: 7u + 3u -10 + 6u - 8 + 5u - 8 = (7 + 3 + 6 + 5)u + (-10 -8 -8) = 21u - 26
At 2:30, they are 70 miles away, at 2:45, they are 55 miles away.
That means, in 15 minutes, they traveled 15 miles....thats 1 mile per minute.
so 2:45....55 miles away...at 1 mile per minute = 2:45 + 55 minutes =
3:40. <== when they arrive at Grandma's house.
3:40 - 1:00 = 2:40.....it took 2 hrs and 40 minutes for the trip....thats 120 + 40 = 160 minutes <== =so the family lives 160 miles from Grandma's house

Answer:
- <u>Each digit has a value ten times the value of the digit to its right.</u>
Explanation:
The given number is 9,999,999.
Each digit has a value according to its place.
The right most 9 is in the place of the ones and its value is 9 × 10⁰ = 9 × 1 = 9.
The second 9 from the right is in the place of the tens and its value is 9 × 10 = 90.
The third 9 from the right end is in the place of the hundreds and its value is 9 × 100 = 900.
The next 9 is in the place of the thousands, so its value is 9,000.
So, each 9 has a value ten times the 9 to its right.
