Answer:
1 56/100 or 1 28/50 or 1 13/25 or 14/9.
Step-by-step explanation:
1.5555555556 rounded is 1.56 which is 1 56/100 which can be made in improper form and made in simpler form.
10x = 15.55555555.
x = 1.55555555.
10x - x is 15.55555555 − 1.555555555.
9x is 14.55555555.
Divide both sides by 9/
x is 14/9.
I guess the only way to use subtraction is to take the total area of the grid and subtract it by the total area around the figure. So it since it is a 10 by 10 grid, it would be 100 (since 10*10=100) minus the area around the shape.

Answer:
27. 3
28. 2a
29. y²
30. 280yz
31. 1
32. 1/3
Step-by-step explanation:
One way to think about a coefficient is this: Set the value of the variable of interest to 1 and evaluate the expression. The value of the expression is the coefficient of the variable of interest.
Here, you're only interested in the variable x, so its coefficient is everything that is not x. The coefficients are ...
27. 3
28. 2a
29. y²
30. 280yz
31. 1 . . . . . a lot of students get tripped up by this one. Setting x=1 makes it obvious.
32. 1/3
_____
Sometimes you're asked for the coefficient in a <em>term</em>. In the case of the term 280xyz, the appropriate answer to that question is 280, <em>the constant that multiplies all the variables</em>. When no constant is showing, the coefficient is 1, as in question 31.
