Enrico is laying 1-ft square tiles on a square bathroom floor. If he needs 81 tiles to cover the floor, how many tiles run along each wall?

moderators are

grace would use 12 apple slices

the equation solved by kelsey is

⇒7 x-   →[given equation]

⇒ 7 x -1/2×(8 x)-1/2×(2)=6 →[distributive property]

⇒ 7 x- 4 x-1=6

⇒7 x- 4 x=6+1→ [ combining like terms]

⇒3 x=7 → [ subtraction and addition property of equality]

⇒x=7/3   →[ division property of equality]

so, we have used for properties to solve the equation

1. distributive property. 2. combine like terms. 3. subtraction and addition property of equality. 4. division property of equality.

i got true and it was right hope this
