19. Kaci spent $170 on 82 gold and silver tickets for the fair. Gold tickets, g, cost $2.50 each; silver tickets, s, cost $1.50 each. The system of equations below can be used to
determine the number of each type of ticket Kaci bought.
g+s= 82
2.5g + 1.5s = 170
How many gold tickets did Kaci buy?

could you reply to this with the question so i can ?

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29

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
