Simplify 2/7b to 2b/7
-1 × (2b/7 + 9) - 8
Simplify 1 × (2b/7 + 9) to (2b/7 + 9)
-(2b/7 + 9) - 8
Simplify brackets
-2b/7 - 9 - 8
Collect like terms
-2b/7 + (-9 - 8)

<u>-2b/7 - 17</u>
Answer: 500m
Explanation:
If the scale of the drawing is 1:500 then the real playground should be 500:1 which is 500m
So since the constant is the same we could divide them. If you know when you divide powers of 10 you subtract so it would be 5.34/5.34 which is 1 and 10^5- 10^-2. 5 - (-2). Which is 10^7 so it would be 1*10^7
