Help fast please In AGHI, GH || JK. Given that IJ= 20, GH=42, and JK = 24, find IG.
wolverine [178]

Answer:

55

Step-by-step explanation:

\frac{IJ}{JK} = \frac{JG}{GH}

\frac{20}{24} = \frac{JG}{42}

Cross multiply

|JG| = \frac{20  X 42}{24}

|JG| = 35

Therefore |IG| = |JG| + |IJ|

|IG| = 35 + 20

|IG| = 55

Please mark me brainiest if correct.

Write the equation with 6 for x

Vk + 2 - 6 = 0

Vk - 4 = 0

Hich value, when placed in the box, would result in a system of equations with infinitely many solutions?
Jobisdone [24]

The value placed in the box that makes the system of equation with infinitely many solution is 12.

<h3>How to solve an infinitely many solution equation?</h3>

An infinite solution has both sides equal. For example, 6x + 2y - 8 = 12x +4y - 16.  If we simplify the equation we will notice both sides are equal. This means the equation has an infinitely many solution.

Hence,

y = -2x + 4

Therefore,

6x + 3y = 12

divide the equation(ii) by 3

2x + y = 4

y = -2x + 4

Therefore, both equation are equal if the the box is filled with 12. This means for the value placed in the box that makes the system of equation with infinitely many solution is 12.
