Area = 16 ft.²
Use the square root process:
√16
√(4 * 4)
2√4 = 4
First let's find the rate at which one person paint one wall. We know it takes 40 minutes for 8 people to paint 4 walls.
If we divide 40 minutes by 4 walls, we find that it takes 8 people 10 minutes to paint ONE wall. Next, we multiply 10 minutes per wall by 8 people to find how long it takes ONE person to paint ONE wall. Since it takes 8 people 10 minutes, reducing the number of people to one will increase the required time by a factor of 10. So it takes ONE person 80 minutes to paint ONE wall.
Now let's use this information to find out how long it takes 10 people to paint 7 walls. First, multiply 80 minutes by 7 since there are 7 times as much wall to paint. We now know that it takes 560 minutes for one person to paint 7 walls. Finally, divide 560 minutes by 10 people.
The answer is 56 minutes.
Simplify each term<span>.
</span><span>10x−20−11=4+3x
</span>Add <span>−20</span><span> and </span><span>−11</span><span> to get </span><span><span>−31</span>.
</span><span>10x−31=4+3x
</span>Move 3x to the left-hand side of the equation<span> by subtracting </span><span>3x</span><span> from both sides.
</span><span>10x−31−3x=4
</span>Add <span>10x</span><span> and </span><span>−3x</span><span> to get </span><span><span>7x</span>.
</span><span>7x−31=4
</span>Since <span>−31</span><span> does not contain the </span>variable<span> to solve for, move it to the right-hand side of the </span>equation<span> by adding </span>31<span> to both sides.
</span><span>7x=31+4
</span>Add 31<span> and </span>4<span> to get </span><span>35.
</span><span>7x=35
</span>Divide<span> each </span>term<span> in the </span>equation<span> by </span><span>7.
