Answer:-qx+p=r
Step-by-step explanation:
No because the equation -2=10 has no solutions. But in -5x=25, x=-5, (do -5x-5 to get 25) making the equation 25=25. therefore, -5x=25 has many solutions. And the equations are not equivalent.
mean=30
Step-by-step explanation:
mean=Efx/n
=300+p/10+p
= 30(10+p)/10+p
=30
That would be 5/8
