NEED HELP ASAP Joni climbed 230 feet up a hill and then rappelled down 300 feet into a valley PART A Write an addition expression to represent the situation PART B Evaluate the expression to determine. How far Joni was from where he started

144.50

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.

a.)the line for function b is steeper
