Answer: 20/27

Step-by-Step Explanation:

Red Chips = 1
Yellow Chips = 9
Blue Chips = 6
Green Chips = 11
Total = 1 + 9 + 6 + 11 = 27

Probability (Yellow or Green) :-
=> (Yellow Chips + Green Chips)/Total
=> (9 + 11)/27
= 20/27

Probability (Yellow or Green) = 20/27

Two lines have the given equations. Use the LINEAR COMBINATION METHOD to solve.
Maurinko [17]

Using linear combination method, the solution to given system of equations are (-7, -15)

<h3><u>Solution:</u></h3>

Linear combination is the process of adding two algebraic equations so that one of the variables is eliminated

Addition is used when the two equations have terms that are exact opposites, and subtraction is used when the two equations have terms that are the same.

<u><em>Given system of equations are:</em></u>

2x - y = 1  ---- eqn 1

3x - y = -6 ------ eqn 2

Subtract eqn 2 from eqn 1

2x - y = 1

3x - y = -6

(-) -------------

-x = 7

<h3>x = -7</h3>

Substitute x = -7 in eqn 1

2(-7) - y = 1

-14 - y = 1

y = -14 - 1 = -15

<h3>y = -15</h3>

Thus the solution to given system of equations are (-7, -15)

Eleanor and her little sister Joanna are responsible for two chores on their family’s farm, gathering eggs and collecting milk.
iris [78.8K]

Answer:

4 dozens

Step-by-step explanation:

<em>Find Eleanor and Joanna's ratio of eggs to milk</em>

Eleanor:

<em>Dozen eggs : gallons of milk</em>

9 : 3

3 : 1

Joanna:

<em>Dozen eggs : gallons of milk</em>

2 : 2

1 : 1

<em>They gather one gallon of milk each which means Joanna has 1 dozen eggs and Eleanor has 3 dozens of eggs.</em>

Total dozen of eggs = 3 + 1 = 4

Therefore, total dozen of eggs the family have per week is 4 dozens.
