10³ = 1 000
17.55 x 1 000 = 17550
<span>3b+7.1=2.5b+11.5
</span>
First, you'd take 2.5b and subtract it from 3b
3b-2.5b+7.1=11.5
Simplify:
.5b+7.1=11.5
then, you would take 7.1, and since it is positive, subtract it from 11.5
.5b=11.5-7.1
Simplify:
.5b=4.4
Lastly, you'd take 4.4 and divide it by .5, leaving the unknown factor alone.
b=4.4/.5
Final answer:
b=8.8
0.00
*First column to your left - ones column (1)
*Column just after decimal place, in the middle - tenths column (1/10)
*Column to the far right - hundredths column (1/100)
The only numbers that can go in these columns are 0-9.

1.54 + 2.37
= (1 + 5/10 + 4/100) + (2 + 3/10 + 7/100)
= 1 + 5/10 + 4/100 + 2 + 3/10 + 7/100
= 3 + 8/10 + 11/100
= 3 + 8/10 + (10/100 + 1/100)
= 3 + 8/10 + (1/10 + 1/100)
= 3 + 8/10 + 1/10 + 1/100
= 3 + 9/10 + 1/100
= 3.91
If I am correct the answer is 369,600 feet per hour.
