iren [92.7K]

Answer:

Step-by-step explanation:

Given that :

Dimension of poster board = 1 yd by 1 yd

Dimension of each poster sign = 1/3 yd by 1/9 yd

Number of poster signs that can be cut :

Area of poster sign = 1/3 * 1/9 = 1/27 yard²

Area of poster board = 1 yard²

Number of poster signs that can be cut :

Area of poster board / area of poster sign

1 yard² ÷ (1/27) yard²

1 ÷ 1/27

1 * 27/1

= 27 poster signs

Here is an equation 2(x + 9) = -15. What are three different equations that have the same solution as that equation? Show or exp

igor_vitrenko [27]

Answer: 1) 2x+18=-15

2) -33+18

Step-by-step explanation: 1) multiply the outer number by the numbers inside the parentheses : 2 times x would = 2 because x is not by itself so it would be X=1x and you are multiplying 2x1 which = 2 and add the variable x so it would be 2×, and same with 18, you multiply 9x2 which =18 and thats how i got 2x+18 doesnt matter if i havent found the x yet because we already know what it equals to which is -15... 2) X=16.5 so to check we do 2×-16.5 which = -33 and add 18 it = -15

The Venn diagram of each situation is a diagrammatic way of representing what the situation stands for

<h3>How to make the Venn diagrams?</h3>

Diagram 1: A ∩ B ∩ C

This means that we shade all intersection points of the sets A, B and C

Diagram 2: (A ∩ B) ∪ C

This means that we shade the intersection points of the sets A and B and the whole of set C

Diagram 3: A ∩ (B ∪ C)

This means that we shade the where the set A intersects with the whole of sets B and C

Diagram 4: (A ∩ B) \ C

This means that we shade the intersection point of the sets A and B without shading any point on set C

Diagram 5: (A\B) ∪ (B\C) ∪ (A\C)

This means that we shade all set A without set B, all set B without set C and all set A without set C. In other words, we shade everything in the set without shading set C
