1.
7x - y = 5
Isolate y
Add y
7x = y + 5
Subtract
y = 7x - 5 2.
5x - 3y = 0
Isolate y
Add y
5x = 3y
Divide
y = 1.66x 3. v=iwh
Isolate w
Divide h
v/h = iw
Divide I
v/hi = w
SOLUTION:
If you drive at 55 mi/h for 110 miles, this means you drovefor 110 / 55 = 2 hours
Your total driving time is 4 hours and 15 minutes which meansthat you drove 2 and 15 minutes at the rate of 35 mi/h
2 hours and 15 minutes = 2×60 + 15 = 135minutes
35 miles / 60 minutes × ( 135 minutes) = 78.75miles
So total miles driven is 78.75 + 110 =188.75 miles
