Jerry is solving the equation 6(9x−10)+2(18−3x)=−8.
step1: 6(9x)+6(−10)+2(18)+2(−3x)=−8
step2: 54x−60+36−6x=−8
which statement best describes the next step that jerry can use to solve this equation?
question 2 options:
subtract 60 from both sides.
add -60 and 36.
add 6x to 54x.
add -8 and -60.

Step-by-step explanation:

6(9x − 10) + 2(18 − 3x) = −8

use the distributive property a(b + c) = ab + ac

6(9x) + 6(-10) + 2(18) + 2(-3x) = -8

54x - 60 + 36 - 6x = -8           combine like terms

(54x - 6x) + (-60 + 36) = -8   Add -60 and 36

48x - 24 = -8        add 24 to both sides

48x = 16           divide both sides by 48

x = 16/48

x = 1/3

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

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x
