Amee buys 7 dvds for $129.50. the total cost, c, is proportional to the number of dvds purchased, d.

what equation represents the situation? what is the cost of 2 dvds?

get it down to a unit rate firstt by dividing the 129.5 by 7 dvds

$18.50

18.5x2=37

the 2 dvds were 37 dollars

Step-by-step explanation:

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

happy to

pls mark as brainliest

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
