3w + 8 - w = 4w - 2(w - 4)
2w + 8 = 4w - 2w + 8
2w + 8 = 2w + 8
0 = 0
Therefore, option b is an identity.
3x - 6x + 2 > 65
Combine like terms.
-3x + 2 > 65
Subtract 2 from both sides.
-3x > 62
Divide both sides by -3
x < -62/3
Answer: 1298 square feet
------------------------------------------------------
Work Shown:
Area of Rectangle on the Left = length*width = c*d = 24*20 = 480
Area of Rectangle in the center = length*width = c*b = 24*10 = 240
Area of Rectangle on the Right = length*width = c*e = 24*17 = 408
Area of top triangle = (base*height)/2 = b*a/2 = 10*17/2 = 170/2 = 85
Area of bottom triangle = (base*height)/2 = b*a/2 = 10*17/2 = 170/2 = 85
Add up the individual areas to get:
480+240+408+85+85 = 1298
The units are in square feet since this is dealing with area.
Answer:
1,715 feets
Step-by-step explanation:
Give the following :
General descent rate of hot air balloon = 200 - 400ft/min
Six balloons descend at a rate of 245 ft/min for four minutes
The total change in altitude for all six balloons :
From speed = distance / time
Speed = 245 ft / min ; time = 7 minutes
Hence distance descended by the six balloons :
245 ft/min × 7 minutes = 1,715 fts
Hence total change in altitude = 1,715 feets
