The answer to this math problem is 6/-4
Katarina [22]3 years ago

Answer:

x = -\frac{6}{4}

Step-by-step explanation:

<u>Method 1:</u>

1. Original Equation: -\frac{4}{9}x = \frac{2}{3}

2. Multiply by 9 on both sides: -\frac{4 * 9}{9}x =  \frac{2 * 9}{3}

Whatever you do to one side you have to do to the other. You would multiply by 9 on both sides because the LCD of 3 and 9 is 9. You want to make it where you can get rid of the fraction.

3. Simplify: -\frac{36}{9}x = \frac{18}{3}

Simplify the numerators of both fractions.

4. Simplify: -4x = 6

Divide both of your fractions to simplify them.

5. Divide: x = -\frac{6}{4}

Divide by -4 on both sides to get x by itself.

What is the slope of a line parallel to the line 4x - 7y = -14?
Yakvenalex [24]
First put the line in y = mx + b (slope intercept) form.

4x - 7y = -14

Subtract 4x from both sides of the equation.

-7y = -4x - 14

Divide all terms by -7.

y = 4/7x + 2

Solution: The slope of a line parallel to 4x - 7y = -14 is positive 4/7.

Luis wants to buy a skateboard that usually sells for $79.35. All merchandise is discounted by 12%. What is the total cost of th
lakkis [162]

Answer:

The total cost of the skateboard is 75.58881, rounded, it's $75.59.

Step-by-step explanation:

Since the merchandise is discounted by 12%, this means there's a decrease in price.

We need to convert our discount to a decimal, 0.12, and then multiply it by the original price. So,

$79.35 × 0.12 = 9.522

Then we subtract: $79.35 - 9.522 = 69.828

Since we have to pay a sales tax of 8.25%, we need to convert that into a decimal, 0.0825, and then multiply the sales tax by 69.828. So,

69.828 × 0.0825 = 5.76081

Now we add 5.76081 to our price, 69.828, which is 75.58881.  75.58881 rounded to the nearest hundredth is 75.59.
