It takes 42 minutes for 6 people to paint 7 walls
<em><u>Solution:</u></em>
It takes 54 minutes for 4 people to paint 6 walls
To find: Minutes required for 6 people to paint 7 walls
If  men can do
 men can do  work in
 work in  days working
 days working  hours per day and
 hours per day and  men can do
 men can do  work in
 work in  days working
 days working  hours per day, then
 hours per day, then

M = Number of men
D = Number of days
H = Number of hours per day
W = Amount of work
Here in this sum,
<em><u>54 minutes for 4 people to paint 6 walls</u></em>

<em><u>Minutes required for 6 people to paint 7 walls</u></em>

<em><u>Substituting the values in formula, we get</u></em>

Thus it takes 42 minutes for 6 people to paint 7 walls
 
        
             
        
        
        
Answer:
Step-by-step explanation:
6(5+x) = 30 + 6x
1. Distribute the 6 to both the 5 and the x. 
7x5x3 = 105
1. Just multiply them together.
28 - 3(2+4)/9 = 26
1. PEMDAS
2. Add inside the parenthesis: 28 - 3 x 6 / 9
3. Multiply: 28 - 18 / 9
4. Divide: 28 - 2
5. Subtract: 26
 
        
             
        
        
        
2 weeks = 14 day
14 * 15 = 210 seconds
210/60=3 hours and 30 minutes or 3.5 hours.
