Which of these strategies would eliminate a variable in the system of equations? 23 - 5y = 13
- 3x + 2y = 13

Choose all answers that apply:

A. Subtract the bottom equation from the top equation.

B. Multiply the top equation by 3. multiply the bottom equation by 2. then add the equations.

C. Multiply the top equation by 2, multiply the bottom equation by 3, then add the equations

Multiply the top equation by , multiply 3 the bottom equation by 2, then add the equations.

Step-by-step explanation:

6x - 15y = 39

+ (- 6x + 4y) + (26)

- 11y = 65

ian gonna lie that is way to much

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
