Direct variations take the form y=kx. We need to solve for y in order to find k. 

<span>3x+5y=0 </span>
<span>5y=-3x </span>
<span>y=(-3/5)*x </span>
<span>k=-3/5.</span>

Which of the following is a correct interpretation of the expression -4 - (-7)?
Zielflug [23.3K]

Answer:

D

Step-by-step explanation:

So we have the expression:

-4-(-7)

First, simplify. Two negatives make a positive. Therefore, the -(-7) turns into +7:

-4-(-7)\\=-4+7

When adding on the number line, we move to the right.

Therefore, the correct interpretation is the value 7 digits to the <em>right</em> of -4.

D is the correct answer.

A'Reana earns a weekly allowance for doing chores around the house and for keeping all of her grades above a C. During a particu
JulsSmile [24]

Answer:

<em>Answer: A'Reana's weekly allowance is $100</em>

Step-by-step explanation:

<u>Backward Solution</u>

To solve some problems, we can work backward, using the inverse operations, to arrive at the solution.

The problem explains a sequence of expenses A'Reana does with her weekly allowance. In the end, she had $37.50.

That final balance came when she last spent $7.50 on a pizza. Thus, before that, she had $37.50+$7.50=$45

This balance is half of her previously remaining money. The other half was spent on a new shirt. Thus she had 2*$45=$90.

Those $90 were left after she gave $10 to her friend Taylor, thus, the initial money was $90+$10 = $100

Answer: A'Reana's weekly allowance is $100

0.7x+6=0.3(4x+6)−2x
Gelneren [198K]

Answer: x=-2.8

Step-by-step explanation:

Given the following equation:

0.7x+6=0.3(4x+6)-2x

You can follow these steps in order to solve for "x" and find its value:

1. Apply Distributive property on the right side of the equation:

0.7x+6=0.3(4x+6)-2x\\\\0.7x+6=1.2x+1.8-2x

2. Subract 0.7x from both sides and add the like terms:

0.7x+6-(0.7x)=1.2x+1.8-2x-(0.7x)\\\\6=-1.5x+1.8

3. Subtract 1.8 from both sides:

6-(1.8)=-1.5x+1.8-(1.8)\\\\4.2=-1.5x

4. Finally, divide both side of the equation by -1.5:

\frac{4.2}{-1.5}=\frac{-1.5x}{-1.5}\\\\x=-2.8
