Answer:
m=5
Step-by-step explanation:
1) Add 2m on both sides simplify
(-5+9m-20=20)
2) Add 20 on both sides to simplify
(-5+9m=40)
3) Add 5 on both sides to simplify
(9m=45)
4) Divide by 9 on both sides to isolate m.
(m=5)
5) You have approached your solution.
Hey it's me again if you like my answer please mark it as the brainliest that would be much appreciated. Thanks! :D
Answer: 
Step-by-step explanation:
The equation of the line in Slope-intercept form is:
Where "m" is the slope of the line and "b" is the y-intercept.
Find the slope with this formula:
Given the points (-10,-7) (3,-7), substitute values into the formula. Then:
Substitute the slope and any point into and solve for "b":
Then, substituting "m" and "b" into the equation , you get that the equation of this line is:
Answer: The answer I got was A) 16
Step-by-step explanation:
Hope this helps!!!!
As the complete angle is right angle that is 90°
So both the angles should add up to 90°
(3x+2) + (x+16)=90
combine the like terms
4x+18 = 90
Subtract 18 from both sides
4x= 72
divide both sides by 4
x=18
Answer: 28.8%
Step-by-step explanation:
First find out what her speed is:
Speed = Distance / Time
= 50 / 45
= 1.11 meters/second
Now her speed is:
= 50 / 35
= 1.43 meters/ second
The percentage increase in her speed is:
= (New speed - Old speed) / Old speed
= (1.43 - 1.11) / 1.11
= 0.288
= 28.8%
