Answer:
D) 1/9
Step-by-step explanation:
The property that allows 7 + 9 + 3 = 7 + 3 + 9 is called the Commutative Property of Addition and Multiplication. This means that as long as the sign is either a multiplication symbol or an addition symbol, we can move (or "commute") the values wherever we want and the expression will still equal the same amount.
Hope that helped =)
Answer:
Larry would be wrong if 2(as a prime number) is part of the numbers that has 2 at its ones place, but if 2 is not there, then he is correct.
Step-by-step explanation:
Firstly, we need to know what a composite number is. In simple terms, a composite number is a number that is not a prime number. Meaning that, if a number has more than two factors (1 and itself which is the definition for a prime number), then the number is a composite number.
Larry says all numbers that have 2 in their ones place are composite. It depends, if 2 is the only number that makes up the digit, that is the number itself is 2, then it's obviously a prime number. But any other number having 2 at its ones place is definitely a composite number because the number has more than 2 factors; 1, itself and 2. Example:
12, some of the factors is 1, 12 and 2. Therefore it is a composite number.
Larry would be wrong if 2(as a prime number) is part of the numbers that has 2 at its ones place, but if 2 is not there, then he is correct.
the answer is it is proportional
Answer: it should be 28
Step-by-step explanation: because the way the other problems are solved is the right side of the triangle times the bottom and then adding the left side of the triangle, ( 9x8+7=79 ) ( 5x5+5=30) so to get the answer you’d just multiply 24x3= 72 , then subtract 100-72= 28
