Ethel is arranging rides so that 27 members go bowling. some people can ride in a van that belonges to the center where they meet the rest must ride in cars if 12 can go in the van and 5 can go in each car how many cars will they need?

Number of cars needed=3

Step-by-step explanation:

Ethel is arranging rides for 27 members.

If 12 can go in the van and 5 can go in each car.

Let c cars are needed

Then, 12+5c=27

5c=27-12

5c= 15

c= 15/5

c=3

Hence, number of cars needed equals:

3

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
