The solution set is (9.5, 3.5). Explanation: 9.5(2)+3.5(2) is the same as 19+7 which equals 26. These same numbers are used for x-y=6, which is 9.5-3.5=6.
The rate of change is the slope.
That equation is (practically) in the form of y=mx+b because T(d) is very similar to y.
T(d) = 39.27d+36.77
y = mx+b
In this case, d would equal x. T(d) would equal y. 36.77 would equal b.
m is the slope, or the rate of change.
The rate of change is the variable, d, or the answer choice, a: the number of drinks purchased.

Marsh Trail is longer than Woodland trail by 2.5 miles
Step-by-step explanation:
A town park has 2 biking trails
1. Marsh Trail is 5 and three over ten miles long
2. Woodland trail is 2 and 4 over 5 miles long
We need to find that Marsh Trail is how much longer than
Woodland trail
To do that we will subtract the length of the Woodland trail from the
length of the Marsh Trail
∵ The length of Marsh Trail is 5 and three over ten miles
- 5 and three over ten = 
∵
= 0.3
∴
= 5.3 miles
∵ The length of Woodland trail is 2 and 4 over 5 miles
- 2 and 4 over 5 = 
∵
= 0.8
∴
= 2.8
∴ The difference = 5.3 - 2.8
∴ The difference = 2.5 miles
Marsh Trail is longer than Woodland trail by 2.5 miles

Answer:
27
Step-by-step explanation:
First solve 3a - 9= 6
3a - 9 = 6 add 9
3a = 15 divide by 3
a = 5
Now that you know a is 5, put that in the other expression.
5a + 2
= 5(5) + 2
= 25 + 2
= 27
