Answer:
2 and -3
Step-by-step explanation:
Let the numbers be x and y ∴ 4x -2y =-16......................Eqn 1
and x+y=-1.................................Eqn 2
this ⇒x=-1-y. Substitute the value of x to be=-1 -y and putting in Eqn 1 yields the following 4(-1-y)-2y =-16 0r -4-4y-2y=-16
⇒-4-6y=-16 0r =-6y=-12 ∴y is 2
⇒ and x is -3
Step-by-step explanation:
You should always use the least number of significant figures. The exception is exact numbers or constants.
For example, there are 60 minutes in an hour. Even though this number has one significant figure, it is an exact number. So 15 minutes converted to hours would be 0.25 hr.
