The uncovered area is:


Answer:
x=19
Step-by-step explanation:
You make your equation, 7x-8=6x+11.
Now you subtract 11 from both sides, so that now the equation is 7x-8-11=6x+11-11, or 7x-19=6x.
You need to now subtract 7x from both sides, so that it's 7x-19-7x=6x-7x, or -19=-x.
After that, you just reverse it so that it's positive, so x=19.

<span>The number rounded all the way is 3,000. If you round to the hundreds you have to remove the units number which is 9, then you have to increase the tens number to 9, resulting 2,690.
