Solve 3kx + 24 = 9 kx for x.
Answer:
Step-by-step explanation:
3kx + 24 = 9kx
First subtract 3kx to both sides.
24 = 9kx - 3kx
24 = 6kx
Divide both sides by 6
24/6 = kx
4 = kx
Divide both sides by k.
4/k = x

1: Ten baseballs weigh 1,417.4 grams. About how much does 1 baseball weigh? 2: Round your answer to the nearest tenth of a gram. 3:Round your answer to the nearest gram. 4: Which answer would you give if someone asked, "About how much does a baseball weigh?" Explain your choice.
Answer:
141.74 grams
Step-by-step explanation:
According to the given situation, the computation of each baseball weighs is shown below:-
Each baseball weighs = Total weight of all ten baseballs ÷ Total amount
= 1,417.4 ÷ 10
= 141.74 grams
Therefore for determining the each baseball weighs we simply applied the above formula.

9) Carla's credit card statement showed that she owed $350. She
Thade a payment of $200, then she charged $23 for gasoline She
returned a sweater she had charged earlier for a refund of $35
Then she charged $15 at the bookstore. What is her new balance?
35
Answer:
the answer is -153
Step-by-step explanation:
350-200(she paid off 200$)=150
150+23(she charged her account 23$)=173
173-35(she paid off 35$)=138
138+15(she charged her account 15$)=135
her new balance is -153$ because that is how much she has left to pay off before she reaches 0 then she can gain credit.

You are going on a field trip and need to choose where to go, The zoo charges a $100 fee plus $10 per student. The museum charges $200 plus $5 per student. How many students have to go on the trip to make the museum a better deal
Answer:
21 kids have to go on the trip to make the museum a better deal
Step-by-step explanation:
Zoo: y=10x+100
Museum: y=5x+200
10x+100=5x+200
5x=100
x=20
When 20 kids go on trip the costs will be the same. Therefore, once 21 kids go the museum will be cheaper then the zoo as it is increasing at a rate of 5 dollars
Jill says that 23/1000 can be written as 0.23. Which explains whether or not Jill is correct? A. Yes, Jill is correct. The fraction 23/1,000 is equivalent to 0.23. B. No, Jill is not correct. The fraction is equivalent to 0.023. The decimal 0.23 is equivalent to. C. No. Jill is not correct. The fraction is equivalent to 0.0023. The decimal is 0.23 is equivalent to 23/100. D. No, Jill is not correct. The fraction 23/1,000 is equivalent to 2.3. The decimal 0.23 is equivalent to 23/100. D. No, Jill is not correct. The fraction 23/1,000 is equivalent to 2.3. The decimal 0.23 is equivalent to 23/100.
Answer:
B. No, Jill is not correct, the fraction is equivalent to 0.023.
Step-by-step explanation:
The given fraction is [tex]\frac{23}{1000}[/tex]
Observe that in the denominator there is 1000, which has three zeros after 1.
In changing the given fraction to decimal, there must be 3 significant digits after the decimal.
According to this option (b) is correct.
Moreover, when 23 is divided by 1000, we have
[tex]\frac{23}{1000}=0.023[/tex]
But Jill says that 23/1000 can be written as 0.23, so, Jill is not correct.
Hence option (b) is correct,

Which function has a greater degree?
Answer:
I think it's either B or C because A and D don't make sense in my opinion.
Step-by-step explanation:
The degree of the p (x) is greater because r (x) is quadratic.
What is Quadratic equation?An algebraic equation with the second degree of the variable is called an Quadratic equation.
Given that;
The function p (x) is,
⇒ p (x) = 4x³ - 2x² + 15
And, The function of r (x) is find by table.
Here, By the given table;
The degree of r (x) is 2, because it is quadratic.
And, The degree of p (x) is 3.
Thus, We can conclude that;
The degree of the p (x) is greater because r (x) is quadratic.
