Answer:
50
Step-by-step explanation:
Add all of the values together, which will equal 600. Divide this number by the total amount of numbers that are there, which will be 12.
600 / 12 = 50

7 times 1 times 2 =14
2 times 3 times 3=18
Answer:
2x - 15
3a + 17
1000/y
Step-by-step explanation:
1.
15 less means subtract 15
twice a number is 2x
Answer: 2x - 15
2.
increased by 17 means add 17
3 times a number is 3a
Answer: 3a + 17
3.
1000 divided by y number of employees
Answer: 1000/y
Answer:
6) Option B) distributive property is correct
Therefore 5+2(x-7)=5+2x-14 are equivalent by using distributive property
7) Option B) distributive property is correct
Therefore x+3(7-x)=x+21-3x are equivalent by using distributive property
Step-by-step explanation:
6) Given that the expressions 5+2(x-7) and 5+2x-14 are equivalent
To verify that the given expressions are equivalent by which property :
5+2(x-7)
=5+2(x)+2(-7) ( by using the distributive property a(x+y)=ax+ay )
=5+2x-14
Therefore 5+2(x-7)=5+2x-14 are equivalent by using distributive property
Therefore option B) distributive property is correct
7) Given that the expressions x+3(7-x) and x+21-3x are equivalent
To verify that the given expressions are equivalent by which property :
x+3(7-x)
=x+3(7)+3(-x) ( by using the distributive property a(x+y)=ax+ay )
=x+21-3x
Therefore x+3(7-x)=x+21-3x are equivalent by using distributive property
Therefore option B) distributive property is correct
