Dixon and his little sister Ariadne stand next to each other on the playground on a sunny afternoon. Their mother measures their shadows. Dixon's shadow is 18 feet long and Ariadne's shadow is 15 feet long. If Dixon is 6 feet tall, how tall is Ariadne?

Answers

Ariadne is 5 feet tall because 18 is 6x3 which would mean you would have to divide 15 by three to get the answer which is 5.
She would be 5ft tall because if you set the problem up in a ratio and cross multiple and divide 5 is your answer

What is the x-coordinate of the solution of the following system of equations?3x + y = 6
x - y = 6

a. -3
b. 0
c. 3

Answers

Answer:

The x-coordinate of of the solution of  system of equations is 3.

Option (c) is correct .

Step-by-step explanation:

As the system of equations are

3x + y = 6

x - y = 6

Now multiply x - y = 6 by 3 and subtrated from 3x + y = 6  .

3x - 3x + y + 3y = 6 - 18

4y = -12

y = (-12)/(4)

y = -3

Put in the x - y = 6

x - (-3) = 6

x + 3 = 6

x = 6 -3

x = 3

Therefore the x-coordinate of of the solution of  system of equations is 3.

Option (c) is correct .

c because x is equal to 3
