If your trying to find the unit rate or the scale of the map, you need to figure out how many kilometers are per centimeters. To get that you need to do 63 divided by 9, witch would get you 7. So to my ability, the answer would be 1 cm per 7 kilometers. Hopefully this answer helped you and I'm hoping its correct.
1. D
2. A
3. C
Question 2 MIGHT be D, but I think it's A
In this question,We have to group the given expression to get 5 as the final answer .
Here we put 5 +20 in parenthesis, that is
And we do the required operations, that is
And we get 5.
53 - 2(3)
53 - 6
47
Hope this helps!
To fill in the first column =
Every day is 7 dollars, which you have already answered.
The second one would be =
day 0 = 30 dollars. And then it would be 4$ for days 1 through 10.
Hope this helps!
