Step-by-step explanation:
Simplifying
4y + -10 = 5 + -1y
Reorder the terms:
-10 + 4y = 5 + -1y
Solving
-10 + 4y = 5 + -1y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add 'y' to each side of the equation.
-10 + 4y + y = 5 + -1y + y
Combine like terms: 4y + y = 5y
-10 + 5y = 5 + -1y + y
Combine like terms: -1y + y = 0
-10 + 5y = 5 + 0
-10 + 5y = 5
Add '10' to each side of the equation.
-10 + 10 + 5y = 5 + 10
Combine like terms: -10 + 10 = 0
0 + 5y = 5 + 10
5y = 5 + 10
Combine like terms: 5 + 10 = 15
5y = 15
Divide each side by '5'.
y = 3
Simplifying
y = 3
Answer:
82
Step-by-step explanation:
<u>Vertical rectangle:</u>
A = bh
A = (5)(10)
A = 50
<u>Horizontal rectangle:</u>
h = 10 - (3 + 3)
h = 4
A = bh
A = (8)(4)
A = 32
<u>Combined:</u>
50 + 32
82

Answer:
<h3>78miles/hour</h3>
Step-by-step explanation:
If a helicopter flies 312 miles against the wind in 2 hours, the speed of the helicopter in air is expressed as shown;
Speed = Distance/Time
Speed = 312miles/2hours
Speed = 156miles/hr
The speed of the helicopter against the wind is 156miles/hr
If it can fly 468 miles in the same amount of time, the speed during this time at this distance will be;
speed = 468 miles/2hours
Speed = 234miles/hr
The speed of the helicopter in still air = Speed while flying - Speed while against the wind
The speed of the helicopter in still air = 234miles/hr - 156miles/hr
The speed of the helicopter in still air = 78miles/hour
