Use PEMDAS to figure out the order of operations:

Parentheses
Exponents
Multiplication/Division
Addition/Subtraction

Solve (-4 + -6) first, as this is in parentheses:

-4 + -6 = -10

10 - 5.3 * -10

Solve 5.3 * -10 next, as this is multiplication:

5.3 * -10 = -53

10 - -53

Now we can solve the equation:

10 - -53 = 63

The answer is 63.

Multiplication
Division
Addition
Subtraction

Parentheses is 1st

-4 + -6 = -10

Then is multiplication. 

-10 × 5.3 = -53

At last, subtract

10 - (-53) is the same as: 10 + 53

10 + 53 = 63

Your answer is 63

Hope this helps :)

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.
