Answer:

They sold a total of 513 turkey sandwiches

Step-by-step explanation:

This is a question on simultaneous equation

Let the number of steak sandwiches  = S

Let the number of turkey sandwiches = T

                                                  T +  S   = 925                    (Equation 1)

                                             4 T + 6 S   = 4,524                 (Equation 2)

Using substitution method to solve the simultaneous equation

                  From Equation 1      T +  S   = 925

                                                           T  = 925 - S

Substitute 925 - S for T in equation 2

                                 4 (925 - S) + 6 S   = 4,524

                                3,700 - 4 S + 6 S   = 4,524

                                           3,700 + 2 S = 4,524

Subtract 3,700 from both sides

                            3,700 - 3,700 + 2 S   = 4,524 - 3,700

                                                       2 S   = 824

Divide both sides by the coefficient of S (i.e. 2)

                                                 (2 S)/2   = 824/2

                                                          S   = 412

Substitute 412 for S in equation 1

                                                  T +  S   = 925

                                               T +  412   = 925

Subtract 412 from both sides

                                      T +  412 - 412   = 925 - 412

                                                         T    = 513

That is, the cafe sold 513 turkey sandwiches and 412 of steak sandwiches

Checks for (Equation 1):

                                                  T +  S   = 925                    (Equation 1)

                                           513 +  412   = 925                    (Equation 1)

Checks for (Equation 2):

                                             4 T + 6 S   = 4,524                 (Equation 2)

                                  4 (513) + 6 (412)   = 4,524                 (Equation 2)

                                     2,052 + 2,472  = 4524

What is the scientific notation of 0.00165?
Ierofanga [76]

Answer:

The answer is 1.65*10^{-3}

Step-by-step explanation:

when writing scientific notation, there must be one number to the left of the decimal point.

To achieve this in this problem, you need to move the decimal point 3 times to the right.

because you are moving the point to the right, the exponent will be negative.

*rule of thumb: moving the decimal to the left will give you a positive exponent, moving to the right will give you a negative exponent*

therefore you answer should be written as:

1.65*10^{-3}

hope this helps :)
