The one-way flight is represented as 150x-100miles. If we have a round trip distance to be computed, then we need to multiply it twice such as the solution is shown below:
(150x-100)*2
300x-200
Therefore, the answer is letter "C" which is 300x-200.
Answer:
Step-by-step explanation:
for missing angle of triangle ABC
let the missing angle be y
31+111+x=180(sum of interior angle of a triangle is 180 degree)
142+y=180
y=180-142
y=38 degree
x=y(being alternate angles)
x=38 degree

➷ r = k/v^2
Substitute the values in:
120 = k/1^2
Multiply both sides by 1^2 to find k
k = 120
Substitute new values in:
r = 120/10^2
Solve:
r = 1.2

To solve for the x, distribute first the numerical coefficients to the terms on the parentheses. This becomes,
7x - 21 = 4x + 20
Transpose all the terms with x and the constant on either sides of the equation,
7x - 4x = 20 + 21
3x = 41 ; x = 41 / 3
Thus, the answer is x = 41/3 which is fourth among the choices.
