Answer:

x = 35

Step-by-step explanation:

First count how many interior angles we have here.

There are 6 interior angles.

so we then can determine the interior sum of the angles here.

Inside angle sum = 180*(6 - 2) degrees = 180*4 = 720 degrees

(4x - 5)+(4x - 3) + 118 +(3x+6) + (3x-3) + 117 = 720 degrees

8x - 8 + 118 + 6x + 3 + 117 = 720 degrees

14x -8 + 118 + 120 = 720 degrees

14x + 230 = 720

14x = 720 - 230

14x = 490

x = 35

It takes 63 minutes for 4 people to paint 9 walls.

alukav5142 [94]

Answer: 7 people need 16 minutes to paint 4 walls.

Step-by-step explanation:

Since we have given that it takes 63 minutes to paint 9 walls ,

So, we will apply "time and work formula" i.e.

$\frac{M_1\times D_1\times H_1}{W_1}=\frac{M_2\times D_2\times H_2}{W_2}$

where,

H denotes number of hours or minutes,

D denotes number of days

M denotes number of men

W denotes work done them,

So, we need to calculate number of minutes for 7 people to paint 4 walls,

$\frac{63\times 4}{9}=\frac{M\times 7}{4}\\\\7\times 4=\frac{M\times 7}{4}\\\\16=M$

So, 7 people need 16 minutes to paint 4 walls.
