Karly buys a model car for $64. Then she spends 2 times as much on supplies to build the model car. How much does Karly spend altogether?

192

Step-by-step explanation:

Supplies = 2 model cost

               = 2*64 = 128

Total cost = model + supplies

                 = 64 + 128

                  =192

She spends $192

The model car is $64

and two times that is $128.

Add the $64 + $128

Im not 100% I did this right but I hope it helps :D

x = 12

y = 15

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
