Answer:
Step-by-step explanation:
Let c represent the total cost of booking either Uber or Lyft for x miles.
Let m represent the number of miles ridden with either Uber or Lyft.
Uber charges $0.80 per mile and a booking fee of $2.30. This means that the total cost of riding with Uber for m miles would be
c = 2.30 + 0.8m - - - - - - - - - -1
Lyft charges $1.07 per mile with no booking fee. This means that the total cost of riding with Lyft for m miles would be
c = 1.07m - - - - - - - - - -2

The equation 
can be used to find the measure of ∠BAC ⇒ 2nd answer
Step-by-step explanation:
Let us revise the trigonometry ratios in the right triangle ABC, where B is the right angle, AC is the hypotenuse, AB and BC are the legs of the triangle
The trigonometry ratios of the ∠BAC, the opposite side to this angle is BC and the adjacent side to it is AB are
In Δ ABC
∵ ∠ BCA is a right angle
∴ The hypotenuse is AB
∵ The adjacent side to ∠CAB is AC
∵ The opposite side to ∠CAB is BC
∵ AB = 13 units ⇒ hypotenuse
∵ CB = 12 units ⇒ opposite
∵ AC = 5 units ⇒ adjacent
- Let us find the trigonometry ratios of angle BAC
∵ m∠CAB is x
∵ 
∴ 
∴ 
∵ 
∴ 
∴ 
∵ 
∴ 
∴
The equation can be used to find the measure of ∠BAC

Answer:
If you use the addition property of equality, what number would you add to both sides of the equal sign to isolate the variable?
You would subtract 5/7 from both sides of the equation
What is the solution?
x = 26/7 or 3 and 5/7
Step-by-step explanation:
x + 5/7 = 31/7
Subtract 5/7 from both sides of the equation:
x + 5/7 - 5/7 = 31/7 - 5/7
x = 26/7
C is the rigth answer because all the other three has two x values in common. :)
