7a. Yes, it has a steady change rate.

7b. Two miles

7c. 20 - Min / 20

Step-by-step explanation:

1. 46.20 / 12 = 3.85

2. 21 * 2 = 42 (Half hour to whole hour)

42 - 35= 7

3. 140 * .4 = 56 (.4 = 2/5)

4. 4.86 / 3 = 1.62 (Base price)

1.62 * 2 = 3.24

5. 450 * 1.5 = 675

6. Goes right two, up one.

7. A .5 decrease every 10 mins.

So 10/20 would equal .5

10 = 1.5 miles left.

1.5 + .5 equals 2 Miles.

its 4 because 2 times 2 is 4, if you double the number two you get four

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
