Step-by-step explanation:
3(5y-3)
Distribute
3*5y -3*3
15y -9
Answer:
No
Step-by-step explanation:
Step 1: Write equation
8u - 1 = 6u
Step 2: Solve for <em>u</em>
- Subtract 6u on both sides: 2u - 1 = 0
- Add 1 to both sides: 2u = 1
- Divide both sides by 2: u = 1/2
∴ u = -1/2 is NOT a solution.
If the length is 3×width then length+width=4×width and the perimeter is 8×width=86, width=86/8=43/4=10.75cm.
The length is 3×10.75=32.25cm.
Answer:
The plane was traveling at 800 mph
Step-by-step explanation:
Step 1: Find the total number of minutes flown by airplane
3 hours * 60 minutes/hour = 180 180 + 33 = 213 total minutes
Step 2: Divide the number of miles flown by the number of minutes
2840 miles / 213 minutes = 13.3333333 miles/minute
Step 3: Multiply the number of miles/minute by 60 to calculate the number of miles/hour
13.3333333 miles/minute * 60 minutes/hour = 800 miles/hour
