Given: 5n - 42 = 12n
Prove: n = -6

I need statements and reasons

5n-42 = 12n

-5n         -5n

-42        = 7n

___          ___

 7               7

-6 = n

Step-by-step explanation:

um for reasoning: get all the n variables to one side and solve for n (dont know how much more to reason)

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
