Answer:
The required equation is 
Step-by-step explanation:
Consider the provided information.
Student on the cross-country team runs 30 minutes a day as a part of her training,
30 minutes = 0.5 hours
As we know 
Let the distance she runs in miles, is represented by D, and her running speed, in miles per hour is represented by S.
Therefore, the required equation is: 
Part (A) At a constant speed of 4 miles per hour for the entire 30 minutes.
Substitute S=4 in above equation.



Hence, the required equation is 
Answer:
Its a i just took the test
Step-by-step explanation:
2x-10=44+8x
Subtract 2x from both sides
-10=44+6x
Subtract 44 from both sides
-54=6x
Divide 6 on both sides
Final Answer: x= -9
Answer: 
Step-by-step explanation:
<u>Given information</u>
∡ 1 = 90°
∡ 2 = 50°
∡ 3 = x°
Total Angle = 180° <em>(Triangle angle sum theorem)</em>
<u>Given formula</u>
∡ 1 + ∡ 2 + ∡ 3 = Total Angle
<u>Substitute values into the formula</u>
(90) + (50) + (x) = (180)
<u>Combine like terms</u>
140 + x = 180
<u>Subtract 140 on both sides</u>
140 + x - 140 = 180 - 140
