Hi there! The answer is 5.
As you mentioned in the question, the amount of chores Janie does is represented by c.
When we know this we can set up an expression which represents the total amount of money Janie earns.
She always receives $3.
She also receives
$2 × the amount of chores
$2 × c = 2c
The expression which represents Janie's total earnings is 3 + 2c.
Now we can start solving.
Subtract 3 from both sides.
Divide both sides by 2.
Hence, Janie must do 5 chores to earn enough money to buy a CD.
Answer:
5.4 , 5.6 , 5.7 , 6.7

Answer:
Probably the 1st picture.
Step-by-step explanation:
keep in mind, the center is 0.
The compound inequality of 4v + 2 > -2 or 3v - 5 < 7 is -1 < v < 4
<u>Solution:</u>
Need to solve following compound equality.
4v + 2 > -2 ------(1)
3v – 5 < 7 ------(2)
Lets first solve (1)
4v + 2 > -2
=> 4v > - 2 - 2
=> 4v > -4
=> v > -1 ------condition 1
On solving second equation we get,
3v – 5 < 7
=> 3v < 7 + 5
=> 3v < 12
=> v < 4 ------condition 2
From condition 1 and 2 we get, -1 < v < 4
Hence on solving given compound inequalities we get -1 < v < 4.
That is v must be between -1 and 4 to satisfy both inequalities
28/24 = 1 4/24 or 1 1/6
to simplify the answer you divide the denominator into the numerator and get 1 4/24
then reduce 4/24 by dividing the greatest common multiple into the numerator and the denominator to reduce the fraction to the lowest terms so 4/24 = 1/6 when it is divided by 4
So that gives us the final answer of 1 1/6
