<h3>Answer:</h3>

29. e = D/(3f²)

30. k=-4, x=41 . . . . matches the 2nd selection

<h3>Step-by-step explanation:</h3>

29. Multiply by the inverse of the coefficient of e. That coefficient is 3f², so you divide by that quantity.

... D = e(3f²)

... D/(3f²) = e . . . . . matches the first choice

___

30. You want to solve for k and use it with a different y-value.

... y = kx

... -96 = k·24

... -96/24 = k = -4

For y = -164, you have

... -164 = -4·x

... -164/-4 = x = 41

The coefficient of variation is -4, x is 41.

For each hour he babysits, Anderson earns $1 more than half of Carey’s hourly rate. Anderson earns $6 per hour. Which equation c
Illusion [34]

Answer: Our required equation would be 6=\dfrac{c}{2}+1

Step-by-step explanation:

Since we have given that

Amount that Anderson earns per hour = $6

According to question, Anderson earns $1 more than half of Carey's hourly rate.

Let the hourly rate of Carey be 'c'.

So, it becomes,

6=\dfrac{c}{2}+1

And the value of c would be

6=\dfrac{c}{2}+1\\\\6-1=\dfrac{c}{2}\\\\5=\dfrac{c}{2}\\\\c=\$10

Hence, our required equation would be 6=\dfrac{c}{2}+1

Triple the difference between 32 and 19. A. 3 x (32 -19) B. 32 - 19 x 3 C. 3 x 32-19 D. (3 x 32)-19
Elza [17]
The answer is A 3x(32-19)

Reasoning: Triple the difference of 32 and 19 would be a 3x multiplication of 32-19, you need parenthesis in order to do 32-19 first because of PEMDAS. SO the answer would be 3x(32-19 because none of the other options would show the equation correctly.
