Answers:

Question 1: y = 5

Question 2: x < 1.6666667

Step-by-step explanation:

<h3>Question 1:</h3>

We have the equation 5x - 2y = 30.

Now, we have to subtract 5x from both sides of the equation.

-2y = -5x + 30

Next, we have to divide the numbers.

y = 2.5x - 15      

Make sure to put in the value of x.

y = 2.5 (8) - 15          

We have to multiply now.

y = 20 - 15      

20 - 15 = 5,

y = 5

<h3>Question 2:</h3>

We have the equation 12x - 4 < 16.

Add 4 to both of the sides of the equation.

12x < 20

Divide the numbers.

x = 20 ÷ 12

20 ÷ 12 = 1.66666667

Hope this helps you!

Answer:

1

Step-by-step explanation:

Probability = number of fruit type/total number of fruit. Total number of fruit = 5 + 9 + 5 = 19.

The probability of drawing an apple is P(apple) = number of apples/total number of fruit = 5/19.

The probability of drawing a peach is P(peach) = number of peaches/total number of fruit = 9/19

The probability of drawing an apple is P(orange) = number of oranges/total number of fruit = 5/19

The probability of drawing either an apple, peach or orange at the first draw of fruit from the bag is

P(apple or peach or orange) =  P(apple) + P(peach) + P(orange)

                                               = 5/19 + 9/19 + 5/19

                                               = (5 + 9 + 5)/19

                                               = 19/19

                                               = 1
