5 - 6 = -1
2 + 7 = 9
-1 × 9 = -9
-9 would be the simplified answer.
Hope this helps!
1 yard = 3 feet, so we would do 3×84, which is 252.
There are 252 feet in 84 yards.
I think what you are looking for is 5x=300 therefore x=60 so at 60cars he would start to make more.
22 is the answer for 23x-1 for x=1
<h2>
Hello!</h2>
The answer is:
1017.88 square feet are blue.
<h2>Why?</h2>
To calculate how many square feet are blue, we need to calculate the area of the bottom of the circular swimming pool.
We need to remember that we can calculate the area of any circle using the following formula:

Now, we know that the diameter of the bottom is equal to 36 feet, so, we can calculate the radius of the bottom using the following formula:

So,

Then, calculating the area we have:

Hence, we have that 1017.88 square feet are blue.
Have a nice day!
