When you multiply or divide a whole number by a power of ten just add the zeros. 5 to the 100000 power is 500000. Five zeros. Hope this helps. Just a little trick and pattern I noticed which helps. :)
Answer:
7 miles
Step-by-step explanation:
You have total of $20
We subtract $2.50 from it since it is the base charge, so now we have:
20 - 2.5 = $17.50
This is for the number of miles at $2.50 PER MILE. To find the number of miles we can travel for this, we have to divide the amount we have (17.5) by the rate per mile (2.5), so we have:
17.5/2.7 = 7
So for a total of $20, we can travel 7 miles (without tip)
Answer:
a
Step-by-step explanation:
Answer:
112
Step-by-step explanation:
use substitution method:
make 2 equations:
44 = 2(l+w) l=w+6
plug in l:
44 = 2 (w+6+w)
combine like terms:
44 = 2(2w+6)
distribute:
44 = 4w + 12
get 4w alone:
44 = 4w + 12
-12 -12
__________
32 = 4w
Divide to get w alone :
32 = 4w
__ __
4 4
w=8
plug w in:
l = w + 6
l = 8 + 6
get l alone on one side:
l = 14
plug l and w in an are equation:
14 x 8 = 112
