Write a system of equations and solve. Three times the first number minus two times the second number equals -7. The second number equals one less than negative three times the first number.

Step-by-step explanation:

Let the numbers be x and y

Three times the first number minus two times the second number equals -7:

The second number equals one less than negative three times the first number:

Substitute y in the first equation and solve for x:

Find the value of y:

The numbers are -1 and 2

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
