Answer:

5x+4

Step-by-step explanation:

well the perimeter is the sum of all sides

so we have

P=4x+2x-6+10-x\\\\P=(4x+2x-x)+(-6+10)\\\\P=5x+4

Answer:

P = 5x+4

Step-by-step explanation:

To find the perimeter, sum the sides

A triangle has 3 sides

P = 4x+ 2x-6 + 10-x

Combine like terms

P = 4x+2x-x    -6+10

P = 5x +5

Alexander and Jo live 5 miles apart. They decide to leave their homes at 3 p.M. And travel toward each other. If Alexander bikes
lukranit [14]

Answer:

Step-by-step explanation:

Here is an illustration of the problem:

             ----------------------------->|<------------------

            A                                  t                     J

Alex and Jo start from their separate homes and drive towards one another.  The t indicates the time at which they meet, which is the same time for both.  Filling in a d = rt table:

              d           =        r        x        t

Alex                              14                t

Jo                                   6                t

The formula for motion is d = rt, so that means that Alex's distance is 14t and Jo's distance is 6t.

             

                      14t                               6t

   ---------------------------------->|<------------------

   A                                       t                      J

The distance between them is 5 miles, so that means that Alex's distance plus Jo's distance equals 5 miles.  In equation form:

14t + 6t = 5 and

20t = 5 so

t = .25 hours or 15 minutes.

If they leave their homes at 3 and they meet 15 minutes later, then they meet at 3:15.

OleMash [197]

Answer:

Step-by-step explanation:

Discount = 15% of 45

=\frac{15}{100}*45\\\\=\frac{675}{100}=6.75

= $6.75

Price of the video game = 45 - 6.75 = $38.25

Tax = 7%of 38.25

=\frac{7}{100}*38.25\\\\=\frac{267.75}{100}=2.6775

Price paid by Fatima for the video game = 38.25 + 2.68 = $ 40.93
