A taxi driver had 27 fares to and from the airport last Monday. The price for a ride to the airport is $14, and the price for a
OLga [1]

Answer:

(15, 12)

Step-by-step explanation:

Let's generate two systems of equations that fit this scenario.

Number of trips to the airport = x

Number of trips from the airport = y

Total number of trips to and from the airport = 27

Thus:

x + y = 27 => equation 1.

Total price for trips to the Airport = 14*x = 14x

Total price of trips from the airport = 7*y = 7y

Total collected for the day = $294

Thus:

14x + 7y = 294 => equation 2.

Multiply equation 1 by 7, and multiply equation 2 by 1 to make both equations equivalent.

7 × x + y = 27

1 × 14x + 7y = 294

Thus:

7x + 7y = 189 => equation 3

14x + 7y = 294 => equation 4

Subtract equation 4 from equation 3

-7x = -105

Divide both sides by -7

x = 15

Substitute x = 15 in equation 1

x + y = 27

15 + y = 27

Subtract both sides by 15

y = 27 - 15

y = 12

The ordered pair would be (15, 12)

I need help pls asap
lilavasa [31]

Answer:

Step-by-step explanation:

first we are told that side and ae and a f are the same

so that means one side of each triangle is the same

next we are told that that the lines coming off of those sides are both right angles. so we know these are both right triangles

and b/c both of those angle are right angles... the sides ab and ac have to also be the same length.. or the angle could not be a right angle

therefore since two sides are the same length then all 3 must be the same lengths

and b/c all three are the same these two triangles are the same .. congruent
