Veronica earned $150 at work this past week in her paycheck. She wants to buy some necklaces which costs $6 each. She writes a function to model the amount of money she will have left from her paycheck after purchasing a certain number of necklaces. She writes the function, f(x)= 15 - 6x. Determine what x and f(x) stand for in the function.

(1) x=weeks; f(x)= dollars left 

(2) x=dollars left; f(x)= weeks

(3) x=necklaces; f(x)= dollars left

(4) x=dollars left; f(x)= necklaces

Answers

Answer 1
Answer: The answer is (3) x=necklaces; f(x)= dollars left. However, the function should be f(x)=150-6x, because she started with $150.

you would change the denominators to the least common multiple, in this case, 12. then you would change the fractions to 8/12, 14/12, and 7/12. you would add those, and get 29/12. divide 29 by 12, and get 2. add the rest to get 2 5/12.
(2)/(3)+1 (1)/(6)+ (7)/(12) \n  \n  (2)/(3)+ 1 (1)/(6)= (2)/(3)+ (1*6+1)/(6)= (7)/(6)+ (2)/(3)= (2*2)/(3*2)= (4)/(6)+ (7)/(6)= (11)/(6)=1 (5)/(6)  \n  \n  (7)/(12)+1 (5)/(6)=  (11*2)/(6*2)= (22)/(12) + (7)/(12) = (29)/(12)=2 (5)/(12)

If 0.46 meter is cut from a 12 meter steel rod, how long is the steel rod after the cut?

Answers

The answer is 11.54 because 12.00 -00.46 is 11.54
The answer should be 11.54 because if you decrease 0.46 from 12 thats what you get

One of the community service groups is going to plant a garden. 2/3 of the space will be used for vegetables. 1/4 of the vegetable space will be used for tomatos. what fraction of the garden will be used for tomatoes? draw a picture below.

Answers

Answer:

1/6 of the vegetables space will be used for the tomatoes

Answer:

1/12 of the Garden

Step-by-step explanation:

When adding fractions, the denominators need to be the exact same number. Therefore, you need to find the LCM. The LCM of 3 and 4 is 12, so all the denominators will be 12.

2/3 * 4/4 = 8/12

1/4 * 3/3 = 3/12

8/12 + 3/12 = 11/12

Now you need to subtract it from 1 (the garden).

12/12 - 11/12 = 1/12

4/3(c+4) + 1 = 2c/c+4

Answers

4/3(c+4) + 1 = 2c/c+4 , where c is not -4 <=>
4 / [3(c + 4)] + 3( c + 4) /[ 3( c + 4)] = 6c / [3( c + 4)] <=>
4 + 3c + 12 = 6c <=>
16 = 3c <=>
c = 16 / 3.
