Tina scored 94, 68, and 88 on her first 3 algebra 1 test. her next test is her final which counts double. write and solve an equation that tina could use to determine the minimum grade she must score on her final to have a mean score of 80.

me! what did you put for this question?

step-by-step explanation:

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
