Answer:
all two digit whole number which are divisible by 11 are
22+33+44+55+66+77+88+99=484
30×·15=4.50
then subtract 30 by 4.50 to get 25.50
.0825×30=2.475
now add 2.475+25.50+30= 57.975 round to 57.98
Answer:
3n(7n^3-5n+5n)
21n^3 -15n +15n
21n^4
Step-by-step explanation:
3n(7n^3-5n+5n)
21n^3 -15n +15n
21n^4
35 is the 20% so you multiply 35x5=175. 175 is the whole thing so you minus 175-35=140 which is the remaining money so half of that is 70
