Answer:

x = -5 & y = -3

Step-by-step explanation:

2x - 5y = 5          --------------------------(I)

y = x + 2               -----------------------(II)

Using substitution method

Substitute y = x + 2 in equation (I)

            2x - 5(x + 2) = 5            

      2x - 5*x + (-5)*2 = 5

            2x - 5x - 10  = 5        

Combine like terms

                -3x - 10 = 5               {Add 10 to both sides}

                        -3x = 5 +10

                        -3x = 15                 {Divide both sides by (-3)}

                           x = 15/(-3)

x = -5

Substitute the x = (-5)  in equation (II)

y = -5 + 2

y = -3

The rate StartFraction 165 ounces Over 11 boxes EndFraction describes the relationship between the number of boxes and the weight of the crackers in the boxes. What is the weight, in ounces, of one box?

Total weight of crackers in the boxes = 165 ounces

Total number of boxes = 11 boxes

What is the weight, in ounces, of one box?

Weight per box of crackers =

Total weight of crackers in the boxes / Total number of boxes

= 165 ounces / 11 boxes

= 15 ounces per box

The weight, in ounces, of one box is 15 ounces

Make a table showing the probability distribution for the possible sums when tossing two four-sided dice (the sides are numbered
alexira [117]
We would have the following sample space:
(1, 1), (1, 2), (1, 3), (1, 4)
(2, 1), (2, 2), (2, 3), (2, 4)
(3, 1), (3, 2), (3, 3), (3, 4)
(4, 1), (4, 2), (4, 3), (4, 4)

Those give us these sums:
2, 3, 4, 5
3, 4, 5, 6
4, 5, 6, 7
5, 6, 7, 8

P(sum of 2) = 1/16 =0.0625
P(sum of 3) = 2/16 = 0.125
P(sum of 4) = 3/16 = 0.1875
P(sum of 5) = 4/16 = 0.25
P(sum of 6) = 3/16 = 0.1875
P(sum of 7) = 2/16 = 0.125
P(sum of 8) = 1/16 = 0.0625
