You are facing South. You make an about face, then turn 90 degrees right. What direction are you facing?

Answers

If you face South, perform an about face (180-degree turn), and then turn 90 degrees to the right, you will be facing West.

If you are facing South and make an about-face, then turn 90 degrees right, you will be facing West. This is because an about-face means to turn around 180 degrees, so you would now be facing North.

Then, turning 90 degrees to the right from the North would put you in the direction of the West. To summarize, if you start off facing South, making an about-face means turning around 180 degrees to face North.

From there, turning 90 degrees to the right puts you in the direction of the West. Therefore, you would be facing West after making an about-face and turning 90 degrees to the right.

Answer:

x = 4 and y = 1

Step-by-step explanation:

The given equations are :

2x+5y = 13 ...(1)

3x-2y = 10 ...(2)

We can use elimination method to solve the given equations.

Multiply equation (1) by 3 and equation (2) by 2.

6x+15y=39 ...(3)

6x-4y=20 ...(4)

Subtract equation (3) from (4).

6x-4y-(6x+15y) = 20-39

6x-4y-6x-15y = -19

-19y=-19

y = 1

Put the value of y in equation (1).

2x+5y = 13

2x+5=13

2x=8

x = 4

So, the solution of the given equations are x = 4 and y = 1.
