Mackenzie is working two summer jobs, making $7 per hour babysitting and making $13 per hour landscaping. In a given week, she can work at most 14 total hours and must earn a minimum of $130. Also, she must work a maximum of 5 hours babysitting and a maximum of 11 hours landscaping. If xx represents the number of hours babysitting and yy represents the number of hours landscaping, write and solve a system of inequalities graphically and determine one possible solution.

Step-by-step explanation:

Given that

                                                                 1

John can run 100 meters dash in 16     seconds .

                                                                  5

Savanna 's time is 19.8 seconds .

Here we have John time in mixed fraction and Savanna's time in decimal .

Converting mixed fraction into improper .

     1                      16 * 5     +  1                 80 + 1                 81

16      =        =   =   -

    5                           5                                  5                      5

Thus we got John time as 81 /5 seconds .

Converting Savanna's time in fraction , we get

 19 8

 seconds .

  10  

We have two fractions with different denominator .

One is having denominator 5 and another is having denominator 10 .

We need to make the denominator same of both the fraction .

We need to make denominator 10 .

Multiply John fraction by 2 in both numerator and denominator by 2 to make denominator 10 .

81 * 2               162

 =       seconds .

5 *  2                   10

John is taking less time than Savanna . Thus John is faster .

Difference

198          162            36

 -         =   seconds  

10              10              10

Thus John is faster by  (36/10 ) seconds  =  3.6 seconds

i think u have 12 apples sorry again i don't really know if it correct i'm just tryna hrlp people out.
