Answer:
The answer is equal to 3/10
Step-by-step explanation:
The values are not very clear
If it's the product of 3/3 and 3/10
Then 3/3 x 3/10
= 9/30
= 3/10
This way Sally travels 12+9=21 kilometers.
If there was a direct way she could go to work, that way would have been 15 km (because her way to work forms a right-angled triangle).
Therefore her journey would be 21-15=6 km shorter. Choice A.
2 ≤ 2w +4 ≤ 12
Subtract 4 from all 3 terms:
-2 ≤ 2w ≤ 8
Divide all 3 terms by 2:
-1 ≤ w ≤4
