Answer:
-7
Step-by-step explanation:
3m-4=5m+10
-2m-4=10
-2m=14
m=-7
21/7=3mins per wall with 5 people.
Because we assume that all of the people paint at the same rate, 3 X 5=15 mins for one person working alone.
15/3=5 mins per wall with 3 people X 10 people= 50 mins for 3 people to paint 10 walls.
The answer is 50 mins.
Answer:
<h2><em><u>z</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>-</u></em><em><u>5</u></em></h2>
Step-by-step explanation:
-4(2z+6)-12 = 4
=> -8z - 24 - 12 = 4
=> -8z = 4 + 12 + 24
=> -8z = 40

=> <em><u>z</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>-</u></em><em><u> </u></em><em><u>5</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
To find the answer you do 19×19= 361 and do 361×3.14= 1,133.54 The area of the stage is 1,133.54
-5 and 5 are the two numbers that are the answer to this equation.
