1.2+d+0.4=97 you add 1.2+0.4=1.6
1.6+d=97 you isolate the variable by subtracting 1.6 on both sides, 97-1.6=98.6
d=98.6

Why and how do you do this I am having a hard time
sukhopar [10]

Answer:

Peter walks at a rate of 13/4 miles per hour.

Step-by-step explanation:

Peter walks at a rate of 13/4 miles per hour because every hour, <em>represented by x</em>, he walks 3.25 hours or 13/4. y is the total miles he walked so if he walks two hours the y would equal 6.5 or 26/4 and the x would equal 2.
