1 answer:
VikaD [51]2 years ago
4 0

Answer:

(2,-7)

Step-by-step explanation:

Plug in the numbers to test and see if it gives you -17 and -8.

Option 1. 2(-4)+3(2)

= -8+6 = -2. Not it.

Option 2. 2(2)+3(-7)

4 - 21 = -17 Works. Try the second equation to make sure.

3(2)+2(-7)

6-14 = -8. Works.

(2,-7) is the answer.

Korvikt [17]

Answer:

Step-by-step explanation:    ts  6  11    19    56

Laura, David, and Carlos served a total of 115 orders

David served 3 times as many orders as Carlos.                 David = 3x

Laura served 10 more orders than Carlos.                      let Carlos = x

How many orders did they each serve?                           Laura  =  x + 10

     Carlos  +  David  +  Laura  = 115

          x  +     3x    +    x+10       = 115

                        5x + 10     =  115

                               5x   =  115 - 10

                               5x   =  105

                                x   =   21    Carlos

                                          63   Davide

                                          31    Laura

                 add then up    115  Total

lina2011 [118]
We know that
<span>the probability of the Galaxy team winning is 22%------> 0.22
</span>the probability of the Galaxy team losing is 100%-22%----> 78%-----> 0.78

<span>the probability of the Komets team winning is 47%------> 0.47
</span>the probability of the Komets team losing is 100%-47%----> 53%-----> 0.53

therefore
<span>the probability of the comets losing their race and the galaxy winning theirs is
0.53*0.22=0.1166------> 11.66%

the answer is
11.66%</span>
