Subtract 5n from 10n which gives you 10=5n-65 and then add 65 to 10 so now 75=5n then divide 75 by 5 which gives you 15. What you do to one side you have to do to be other

Answer: 15

Step-by-step explanation: 5n + 10=10n - 65

                                           -10n        -10n

                                       ------------------------------

                                            -5n +10 = -65

                                                   -10    -10

                                        ----------------------------

                                              -5n = -75

                    divide -5 on both sides and you should get positive 15

--2m + 4n2 for m = -6 and n=-5<br> Evaluate the expression
Tamiku [17]

Answer: 112

Step-by-step explanation:

Since we were given m and n, we plug them into the expression and solve.

-2(-6)+4(-5)²            [exponent]

-2(-6)+4(25)            [multiply]

12+100                     [add]

112

Now, we know that the value of the expression is 112.
