Answer:

2) x = 6    y = 7      3) x = -5    y= 2

Step-by-step explanation:

2) 10x - 8y = 4

   2(-5x + 3y = -9)

-10x + 6y = -18

 10x - 8y =   4      Add both equations together

         -2y = -14

         y = 7            Divide both sides by -2

10(x) - 8(7) = 4       Plug in 7 for the y to solve for x

10x - 56 = 4  

     + 56 + 56        Add 56 to both sides

10x = 60

x = 6                      Divide both sides by 10

3) Where the two lines intersect, that is the solution to x and y.

The lines intersect at (-5,2). x = -5      y = 2

A nurse sees 24 patients in 5 hours. At this rate, approximately how many patients will the nurse be able to see in a 8-hour per
Vikki [24]

Hi!

We will solve this using proportions, like this:

24 patients in 5 hours

x patients in 8 hours

_________________

x = (24*8)/5

x = 192/5

x = 38,4

The nurse will be able to see 38,4 patients in a 8-hour period, but because it's patients we are talking about, living things which can't be represented in decimal form, the nurse will be able to see approximately 38 patients in a 8-hour period.

Hope this helps!

Inessa05 [86]

Answer:

The probability that the coin will show tails, the spinner will land on yellow or green (out of yellow, green, blue), and the cube will show a three is \frac{4}{3}  

Step-by-step explanation:

Given : Fred flips a coin, spins the spinner, and rolls a standard number cube.

To find : The probability that the coin will show tails, the spinner will land on yellow or green (out of yellow, green, blue), and the cube will show a three ?

Solution :

First we find probability one by one,

1) Flips a coin - Head, Tail

Total number of outcome = 2

Favorable outcome (getting a tail) = 1

Probability that the coin will show tails is P(T)=\frac{1}{2}

2) Spins the spinner - yellow, green, blue

Total number of outcome = 3

Favorable outcome (land on yellow or green) = 2

Probability that the spinner will land on yellow or green P(S)=\frac{2}{3}

3) Rolls a standard number cube - 1,2,3,4,5,6

Total number of outcome = 6

Favorable outcome (show a three) = 1

Probability that the cube will show a three P(C)=\frac{1}{6}

The probability that the coin will show tails, the spinner will land on yellow or green (out of yellow, green, blue), and the cube will show a three is

P=P(T)+P(S)+P(C)

P=\frac{1}{2}+\frac{2}{3}+\frac{1}{6}

P=\frac{3+4+1}{6}

P=\frac{8}{6}

P=\frac{4}{3}

Therefore, The probability that the coin will show tails, the spinner will land on yellow or green (out of yellow, green, blue), and the cube will show a three is \frac{4}{3}
