Answer:
hi if you want to solve fore x and y there must be 2 equations .
Step-by-step explanation:
so that you could solve them simultaneously
-7x + 2y = 4
here 2y - 4 = 7x
( 2y -4)/7 = x

Answer:
Step-by-step explanation:
each of the 6 number has a 1/6 chance of being rolled
1 2 3 4 5 6
1/6 1/6 1/6 1/6 1/6 1/6
Every time the cube is rolled there is a 6/6 chance of any number comes up
1/6 + 1/6 + 1/6 + 1/6 + 1/6 + 1/6 = 6/6 or 1
What is the probability of NOT rolling a 2? Any other number
1 2 3 4 5 6
1/6 + 0 + 1/6 + 1/6 + 1/6 + 1/6 = 5/6 or 0.8333
Answer:
(1) A. Commutative property, (2) B. Associative property, (3) C. Identity property.
Step-by-step explanation:
(1) This equality shows a case of commutative property, which states that:
,
Hence, the correct answer is A.
(2) This equality shows a case of associative property, which states that:
,
Hence, the correct answer is B.
(3) This equality shows a case of modulative property, also known as identity property, which states that:
,
Hence, the correct answer is C.
