Answer:
- a. There are 10 possible ways.
- b.There are 4 ways for a round trip
- c.There are 20 ways without repeating a road.
- d. There are 100 ways of doing a whole round trip.
a. For Surrey to Burnaby there are 2 ways and for Burnaby to Coquitlam 5, multiplying the available road gives us all the combinations.
b.From Surrey to Brunaby and back we have 2 ways going and 2 ways coming back. Multiplying gives us the 4 ways of doing the round trip.
c. If we don't want to repeat the road we will be using both bridges in Surrey to Brunaby beacause there are only 2 and we cant repeat one, and of the 5 avaliable from Burnaby to Coquitlam we will choose 2, that is, first 1 of 5 and then 1 of 4. Multiplying 5 times 4 gives us the ways of going and coming back without repeating.
d. For a whole round trip we choose from the bridges from Surrey to Brunaby twice, 2*2 and the roads from Burnaby to Coquitlam also twice, 5*5, giving us a total for a round trip of 100 different ways of doing it.
Combination Formula: (n = distinct objects, r = how many you pick) n!/(r!(n-r)!
So n = 7, r = 5
n! = 7! = 5040
R! = 5! = 120
(n-r) = 2! = 2
120*2=240
5040/240 = 21
21 combinations!
GCF means the term(s) that 6x and x have.
The GCF is x because:
1. Using multiplication: 6x * x = 6x^2
becomes x(6+x) = 6x^2
GCF is x.
Good luck to you!

Answer:
pretty sure its store b Step-by-step explanation:
because 15 percent of 75 is 11.25 and that means you're going to pay 63.75, but store b you only pay 60. Store c you buy it full price but your getting 15 dollars rebate only after you purchase it, and its thru mail so its better to pay just the 60
