I have to assume that the instructions are to "simplify <span>-5+7m-20=20-2m."

If that's the case:

Group like terms together:  7m + 2m = 20 +5 + 20
                                                9m      = 45
                                                  m   =  5 (answer)</span>

Translate this phrase into an algebraic expression: Six more than the product of 22 and Jenny's height. Use the variable m to re
Akimi4 [234]
6 + 22m
More = additionProduct = the number that is the result of multiplication6 more (+) than the product (result of) 22*Jenny's Height

If Jenny's height is 5.5 ft:6 + 22*5.5 = 6 + 121 = 127
Hope this helps clear things up a bit.

The Function approximate the velocity (in feet per second) of an object dropped from a height of x feet
grin007 [14]

Answer:

The answer to the question is

It take for the golf ball hit on Mars to reach the ground 8.284 s longer.

Step-by-step explanation:

To Solve the question, we note that the equation of motion is given to us as

h = -1.9·t² + 26·t

Therefore the height

We compare the above equation with the equation of of motion

S = ut - 0.5×g×t² where u = initial velocity = 26 m/s and  - 0.5×g = -1.9

Therefore the acceleration due to gravity om mars = -1.9/-0.5 = 3.8 m/s²

We now have the time taken to maximum height given by

v = u - g·t where v = 0 at maximum height

We therefore have u = g·t → 26 = 3.8×t or t = 26/3.8 = 6.84 seconds

The time taken for ball to hit the ground is 2 × the time to reach maximum height = 2 × 6.84 = 13.684 s

The time longer it takes for the ball on Mars to complete the path up to maximum height and down again is 13.684 s - 5.4 s = 8.284 s.
