"950 feet in 19 minutes" can be expressed as the rate (950/19) (ft/min), and is negative because the diver is descending (going downward).
Simplifying, -950/19 (ft/min) = -50 (ft/min)
In decreasing order:
439.612, 439.261, 439.216, 439.126
I think you're right. I'm in pre-algebra, and sucks at it. Yet, I keep a A.
So the trapezoid has 2 parallel sides making segments AD and BC transversals
Therefore making angle c and angle b add up to 180
(180-3x) + 3x + 180-9x +9x
180 +12x = 360
180= 12x
x= 15
Answer:
Step-by-step explanation:
First solve -5x+9y=-12 for x:
-5x+9y=-12
-5x+9y-9y=-12-9y
-5x=-12-9
-5x=-9-12
-5x/-5=-9/5-12/-5
x=9/5y+12/6
Substitute x into an equation
3(-9/5y+12/6)+2y=22
37/5y+36/5=22
37/5y+36/5-36/5=22-36/5
37/5y=74/5
37/5y/37/5=74/5/37/5
y=2
Substitute y in x=-9/5y+12/6
9/5(2)+12/6
x=6
Solution Set: (6,2)
