1. Ratio- 91:21
2. Reduce- the common factor is 7
3. Answer- 13:3
Answer:
1/5
Step-by-step explanation:
# blue/total # of marbles
3/15 now simplify by dividing both top and bottom by 3
1/5
You would expand becausee it isn't equal to anything
(x+3)^3=(x+3)(x+3)(x+3)
we can use binomial theorem or pascal's triangle
anyway, pascal's triangle is more practicl for this one
so
for the 3rd power
a=x
b=3
=
Answer: 2 states
Step-by-step explanation:
Every year for 8 years, the Williams family visited 6 different states on vacation. This means for 8 years, the family have visited:

= 48 states
Since there are 50 states in total, that means we will subtract 48 from 50. This equals :
50 - 48 = 2 states.
They've 2 states left to visit
