First, we transfer 2m to the other sideand change operation from positive to negative. We also do the same for -4 andchange operation from negative to positive in order to solve this equation.
9m - 2m =-18 + 4
Next we simplysubtract and add from left to right, respectively.
7m = -14
Then, we can now findm by dividing both sides with 7…
7m/7 =-14/7
We’ve arrived at the answer!
m = -2
Checking:
9(-2) - 4= -18 + 2(-2)
-18 - 4 =-18 - 4
-14 = -14
I hopethis helps. :)
9 * m - 4 = - 18 + 2 * m
9 * m - 2 * m = - 18 + 4
7 * m = - 14 /7
m = - 14 / 7
m = - 2
The correct result would be - 2.

The ball have traveled 33 m when it hits the ground for the fourth time.
The correct option is D .
Given, that a ball falls from 12feet.
Analyzing the fall of ball every time.
Fall 1:
Ball dropped from height = 12 m .
Ball returns to half the distance from which it is dropped .
Rebound distance covered by ball = 6 m .
Fall 2:
Ball dropped from height = 6 m .
Ball returns to half the distance from which it is dropped .
Rebound distance covered by ball = 3 m .
Fall 3:
Ball dropped from height = 3 m .
Ball returns to half the distance from which it is dropped .
Rebound distance covered by ball = 1.5 m .
Fall 4:
Ball dropped from height = 1.5 m .
Ball returns to half the distance from which it is dropped .
Rebound distance covered by ball = 0.75 m .
Total distance covered when ball hits the ground for fourth time:
12 + 6 + 6 + 3 + 3 + 1.5 + 1.5
= 33 meters.
The correct option is D .

Final answer:
Given that Pam spends 80 minutes a day practicing math and dance combined, with dancing taking up 20 minutes more than math, it's mathematically impossible for her to spend 60 minutes on dance. She can only spend 50 minutes on dance and 30 minutes on math.
Explanation:
To answer your question, let's first assume that Pam spends 'x' minutes practicing math. According to the information provided, she spends 20 minutes more dancing than doing math, which means she spends 'x + 20' minutes dancing. The total time she spends practicing both activities is 80 minutes. So, 'x' (math) plus 'x + 20' (dance) equals 80.
This can be represented as the equation: x + x + 20 = 80. By solving this equation, we find that 'x' equals 30. This means that Pam spends 30 minutes practicing math and 50 minutes (30 + 20) practicing dance. Therefore, it is not possible for Pam to have spent 60 minutes practicing dance every day because she only spends 50 minutes practicing dance.
