All star sports sells right handed and left-handed baseball gloves and one month 12 gloves were sold for a total revenue of $528 right handed gloves cost $48 each and left-handed gloves cost $36 each how many right handed gloves were sold

Write an equation for the total number of gloves sold

x + y = 12

y = (12-x); use this form for substitution

Write an equation for the total value of the gloves sold

48x + 36y = 528

replace y with (12-x)

48x + 36(12-x) = 528

48x + 432 - 36x = 528

48x - 36x = 528 - 432

12x = 96

x = 96/12

x = 8 rt handed gloves

then

12-8 = 4 left handed gloves

Check this in the 2nd equation

48(8) + 36(4) =

384 + 144 = 528                             Ans- 8 rt hand gloves

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

it would open into a square depending on the type of envelope i’m not sure about the second part
