The equation that represents the cab's total charge is y = 3x + 5 , Option A is the correct answer.
<h3>What is an Equation ?</h3>
A statement that relate two expressions with an equal sign is called an Equation.
It is given that
A cab company charges a $5 boarding
Charges for every mile is $3 per mile
Let x be the mile travelled
The cab's total charge is represented by y
then y = 3x + 5
Therefore the equation that represents the cab's total charge is y = 3x + 5 , Option A is the correct answer.

To solve, the easiest method I've found is to set up 2 fractions and cross multiply. so, x/100 = 105.1/147
12000+875=12875 the total he paid
12000*x/100*4=12875
480x=12875
x=12875/480
x=26,82 %

Answer:
y = 12
Step-by-step explanation:
Triangles ABD and CBD are congruent, so DA = DC:
3y +6 = 5y -18
24 = 2y . . . . . . . . add 18-3y; next, divide by 2
12 = y

<em>Additional comment</em>
In some variations of this question, you may be asked to solve for x. Since the angles are equal, you have ...
3x -1 = 34 -2x ⇒ 5x = 35 ⇒ x = 7 . . . (consistent with ∠ABC = 40°)
