Answer:
r = 15
Step-by-step explanation:
10(8r + 23) = 1430
Divide both sides by 10.
8r + 23 = 143
Subtract 23 from both sides.
8r = 120
Divide both sides by 8.
r = 15
<span> Luis and his
family flew 51 487 miles. This needs to be rounded to the nearest thousands to
know how many miles did Luis and his family flew?
=> 51 487 = where 5 ten thousands, 1 thousands, 4 hundreds, 8 tens and 7
ones.
=> 51 487 = 50 000 + 1 000 + 400 + 80 + 7
=> Round to the nearest thousands. The thousands value is 1, and the number
next to thousands is 4, which is below 5. SO we need to round down.
=> 51 000 miles.
