x = 5

y = -1

Step-by-step explanation:

from second equation,

  • y = -2 + 1
  • y = -1

by putting the value of y in first equation

  • y = -x + 4
  • -1 = -x + 4
  • -x = -1 -4
  • -x = -5
  • x = 5

x = 5 and y = -1

Eric earned $100 in tips on Sunday waiting tables plus an additional $11.50 per hour. He earned at least $250 in all.
snow_tiger [21]

Answer:

13

Step-by-step explanation:

So first Subtract 100 from 250. Since you are trying to find out the amount of hours, you don’t need the tips to count.

The next step is too either do the equation 150 divided by 11.50 or you can multiply 11.50 by 13.

it’s not fourteen because 149.5 is closer to 150 then 161

Hope this helps

In the game of Pick-A-Ball, there are 10 colored balls: 2 red, 4 white, and 4 blue. The balls have been placed into a small buck
MaRussiya [10]

Answer:

The probability of selecting the color of ball that you just selected(a red ball) is P(r) =  \frac{2}{10}

Step-by-step explanation:

From the question we are told that

  The total number of colored balls  is  n  =  10

   The number of red balls is r =  2 red

    The number of white ball is  w =  4

    The number of blue balls is  b  =  4

   The number of balls to be selected is  N  =  2 balls

    The cost of playing picking a ball is  c  =  $10

    The winnings is k =  \$ P(A)

Here P(A) is the probability of obtaining the exact sequence of result  and from the question it  is  P(A) =  0.10

Generally my price according to the question is  

     k =  \frac{0.10 }{10}

=>   k =  0.01

Let assume we selected a red ball

 Generally the probability of selecting a red ball is  mathematically represented as

       P(r) =  \frac{2}{10}
