Agroup of 485 people take a canoe trip they fill up all available canoes that each hold 3 people with 273 people the rest of the group will ride in canoes that each hold 2 people how many canoes will the group need? write equations with unknowns to show your steps

We  have been given that a group of 485 people take a canoe trip. They fill up all available canoes that each hold 3 people with 273 people. The rest of the group will ride in canoes that each hold 2 people.

Let x be number of 3 seater canoes and y be number of 2 seater canoes.

Upon using our given information we can set two equations as:

Upon substituting equation 1 in equation 2 we will get,

Therefore, number of 2 seater canoes will be 106.

Upon solving our 1st equation we will get number of 3 seater canoes.

Therefore, number of 3 seater canoes will be 91.

To find total number of canoes we will add number of 2 seater and 3 seater canoes.

Therefore, group will need 197 canoes.  

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
