Decide whether the two equations are equivalent.

4n + 1= n-8

3n = -9

Yes

Step-by-step explanation:

4n+1=n-8

4n-n+1=-8

3n+1=-8

3n=-8-1

3n=-9

n=-9/3

n=-3

3n=-9

n=-9/3

n=-3

The two equations are equivalent.

Difference in their measurement will be 245532 mm

Step-by-step explanation:

We have given that Priya measured the perimeter of the desk and found the perimeter as 248 m

We know that

So 248 m = 248000 m

And Noah measured the perimeter of the same desk and found as 2468 m  

We have to find the difference in their measurement

Difference will be = 248000 - 2468  = 245532 mm
