Answer:
k = 2.5
Step-by-step explanation:
So we start off with: 2.5(4k+2) = 12k
Let's first distribute.
10k + 5 = 12k
Now let's subtract 10k from both sides.
5 = 2k
Now let's divide both sides by 2.
2.5 = k

Following shows the steps on how to derive this formula
Step 1: If 92% of a number is 230, then what is 100% of that number? Setup the equation.
230
92% = Y
100%
Step 2: Solve for Y
Using cross multiplication of two fractions, we get
92Y = 230 x 100
92Y = 23000
Y = 23000

To make lemonade Jenny combines water and lemon juice in the ratio of 6:1, by volume. How many millilitres of water should she add to make 637 mL of lemonade?
Answers
Answer:
546 mL of water
Step-by-step explanation:
To make lemonade Jenny combines water and lemon juice in the ratio of 6:1, by volume.
Let the amount of water is 6x and that of lemon juice is x.
ATQ,
6x+x = 637
7x = 637
x = 91
Amount of lemon juice = 91 mL
Amount of water = 6x = 6(91) = 546 mL
So, 546 mL of water she should add to make 637 mL of lemonade.

Answer:
f(g(3)) = 3
Step-by-step explanation:
We are told to solve for f(g(3)). This is also saying f of g of 3.
To find f(g(3)), we need to plug 3 in for x in g(x), since it says g(3).
g(x) = 3(3) - 4
Solve.
= 9 - 4
g(x) = 5
Now, we plug that into f(x), because g(x) was placed inside f and replaces the x variable of f(x).
f(5) = 2(5) - 7
Solve.
= 10 - 7
f(5) = 3.
f(g(3)) = 3

To avoid a service fee, your checking account balance must be at least $400 at the end of each month. Your current balance is $432.993. You use your debit card to spend $119.86. What possible amounts can you deposit into your account by the end of the month to avoid paying the service fee?
Answers
Given :
To avoid a service fee, your checking account balance must be at least $400 at the end of each month.
Your current balance is $432.993.
You use your debit card to spend $119.86.
To Find :
What possible amounts can you deposit into your account by the end of the month to avoid paying the service fee.
Solution :
Amount left in the account :
A = $432.993 - $119.86
A = $313.133
Let, amount added is x.
So,
A + x ≥ 400
x + 313.133 ≥ 400
x ≥ 400 - 313.133
x ≥ 86.867
Therefore, possible amount needed is greater than or equal to $86.867 .
Hence, this is the required solution.
