2n = 2
Divide both sides by two
n = 1
What we have to do here is multiply the number of bottles by the number of pennies in each bottle!
so, six bottles by 678 pennies:
6*678=6*(600+70+8)=3600+420+48=4020+48=4068
so she has 4068 pennies
Just count the units.
21) 5x3 is a term. 6x is a term. -7 is a term. 3 terms
you get the idea
22) 4 terms
23) 2 terms
24) one term
I think its rounded to 35
