1 hour and 35 minutes without the break. 60 minutes in an hour, subtract 15 from 50 = 35 minutes. It starts at 3 and ends at 4, which is 1 hour apart. Because there us a break you subtract 30 from the minutes , 35-30=5. So you have 1 hour and 5 minutes.
Answer: y = 5d + 7 / c - 3
Step-by-step explanation:
Step 1: Add -3y to both sides
cy - 7 + -3y = 5d + 3y + -3y
= cy - 3y - 7 = 5d
Step 2: Now, add 7 on both sides
cy - 3y - 7 +7 = 5d +7
= cy - 3y = 5d +7
Step 3: Factor out y
y(c - 3) = 5d + 7
Step 4: Divide both sides by c-3
y(c - 3) / c - 3 = 5d+7 / c-3
Your answer for this should be
y = 5d + 7 / c - 3
Hope this helped!
