Answer:
0.98 minutes
Step-by-step explanation:
First, we have to determine how much time it took for Alaina to run one mile on the first and the second week:
First week:
12 miles → 131.25 minutes
1 mile → x
x=(131.25 minutes*1 mile)/12 miles= 10.93 minutes
Second week:
12 miles → 119.5 minutes
1 mile → x
x= (119.5 minutes*1 mile) /12 miles= 9.95 minutes
Now, we have to find the difference between the time it took to run 1 mile in the first and the second week:
10.93-9.95= 0.98 minutes
She run 0.98 minutes faster in the second week.

Answer:
<h2>
y = -5 </h2>
Step-by-step explanation:
y = 3x − 26
2x − y = 19
2x - (3x - 26) = 19
2x - 3x + 26 = 19
- x = - 7
x = 7
y = 3•7 -26 = 21 - 26 = - 5
