Two hot air balloons are flying above a park. one balloon started at a height of 3,000 feet above the ground and is decreasing in height at a rate of 40 feet per minute. the second balloon is rising at a rate of 50 feet per minute after beginning from a height of 1,200 feet above the ground. given that his the height of the balloons after m minutes, determine which system of equations represents this situation. a. h = 3,000 + 40m h = 1,200 - 50m b. h = 3,000m - 40 h = 1,200m + 50 c. h = 3,000 - 40m h = 1,200 + 50m d. m = 3,000 - 40h m = 1,200 + 50h

h = 3000 - 40m (starts at 3000... decreasing at 40 feet per minute

h = 1200 + 50m (starts at 1200...rises 50 feet per minute

THE ANSWER IS C

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
