This is false.  To find the magnitude of acceleration during some
time interval, all you need to know is the speed at the beginning

-3(n-4)-2n=17 multi step equations

-3(n - 4) -2n = 17

First, expand your problem. / Your problem should look like: -3n + 12 - 2n = 17
Second, simplify -3n + 12 - 2n to get -5n + 12. / Your problem should look like: -5n + 12 = 17
Third, subtract 12 from both sides. / Your problem should look like: -5n = 17 - 12
Fourth, simplify 17 - 12 to get 5. / Your problem should look like: -5n = 5
Fifth, divide both sides by -5. / Your problem should look like: n =  \frac{5}{-5}
Sixth, simplify  \frac{5}{-5} to - \frac{5}{5} / Your problem should look like: n = - \frac{5}{5}
Seventh, cancel 5 out. / Your problem should look like: n = -1

Answer: n = -1

QUESTION POSTED AT 05/12/2019 - 11:00 PM

Alexis recieved an 85,89,92on three tests.How many points does she need to score on her next test in order to have an average of at least 90?

Answer:

94

Step-by-step explanation:

Given: Alexis recieved an 85,89,92on three tests

To Find: Number of points she needs to score in order to have an average of atleast 90.

Solution:

Let the marks scored by Alexis in next test = \text{x}

Marks scored by Alexis in three test = 85

                                                               89

                                                               92

Sum of marks scored by Alexis = 85+89+92

                                                    =266        

Average of Alexis's marks after next test = \frac{\text{Sum of marks of all tests}}{4}

                                                                  =\frac{266+\text{x}}{4}

To have average of at least 90

                                               \frac{266+\text{x}}{4}≥90

                                               266+\text{x}\geq 360

                                               \text{x}\geq 94

Alexis needs to score atleast 94 to have an average of at least 90
