Answer:
B. 4, Heads
4, Tails
5, Heads
5, Tails
6, Heads
6, Tails
Step-by-step explanation:
Given that the cube is labelled 1 to 6 and the coin has a head or a tail, the only outcome when the number cube lands on a number greater than 3 means that the cube lands on 4 or 5 or 6.

In light of this, the possible answers are;
4, Heads
4, Tails
5, Heads
5, Tails
6, Heads
6, Tails

The cost for carpeting 20 square yards is $230.
Further explanation:
First of all, we will calculate the cost for one square yard then will find the final answer.
So,
Given
Total area = 28 square yards
Cost of carpeting 28 square yards = $322
Cost of carpeting one square yard = 322/28 = $11.5 per square yard
Now to find the cost of carpeting 20 square yards
Cost of 20 square yards = 20*11.5
= $230
The cost for carpeting 20 square yards is $230.

1. 5x+ 2(x+6)
= 5x+ 2x+ 2*6 (distributive property)
= 5x+ 2x+ 12
= (5x+ 2x)+ 12 (combine like terms)
= 7x+ 12
The correct answer is C. 7x+12~
