Answer:
y = -32
Step-by-step explanation:
-6(y+15)=-3y+6
Distribute
-6y - 90 = -3y +6
Add 6y to each side
-6y -90+6y = -3y+6y +6
-90 = 3y+6
Subtract 6 from each side
-90 -6 = 3y +6-6
-96 = 3y
Divide by 3
-96/3 = 3y/3
-32 = y
Answer: u= 
Step-by-step explanation:
uw + uq = r To solve for u factor the left side to eliminate the other variables.
u ( w + q) = r Now divide both sides by w+q
u =
Speed of Bruce for the rest of the trip is 30 miles/hour.
Step-by-step explanation:
- Step 1: Total distance = 170 miles. In the trip Bruce's speed = 55 miles/hour. So, in 1 hour, distance covered = 55 miles. Find distance covered in 2 hours and the distance of the last part.
Distance covered in 2 hours = 2 × 55 = 110 miles
Remaining part of the trip = 170 - 110 = 60 miles
- Step 2: Find the speed of Bruce in the remaining part of the trip when time = 2 hours and distance = 60 miles.
Speed = Distance/Time = 60/2 = 30 miles/hour
1/4 c + 3d
c=6 d=7
1/4 (6) + 3(7)
1.5+ 3(7)
1.5+ 21
22.5
