Answer: x = 8
Step-by-step explanation:
x+8-4=12
x+4=12
x=12-4
x=8
7b+12=5b
Subtraction property of equality
7b + 12 - 12 = 5b - 12
Simplifying
7b = 5b - 12
Subtraction property of equality
7b - 5b = 5b - 12 - 5b
Simplifying
2b = -12
Division property of equality
2b/2 = -12/2
Simplifying
b = -6
All you need to do is set the equation for angle b to the equation for angle d and solve for x and then what ever you got for you x value plug it in to one of the tow equations and what ever you get as a final answer is the value of each angle
Since this is just linear we can say that the balloon descends:
(-18ft/min)(10.6min)=-190.8ft (negative because the balloon is coming down)
State the domain of the relation R{(-3,3), (1,1), (0,2),(1,-4),(5,-1)} and then State the range of the relation R={(-3,3), (1,1)

The range is the Y value and the Domain is the X value.
