Answer:

80 pieces of wire.

Step-by-step explanation:

It may not come out evenly. If there is a remainder, it won't matter. Just throw it away and go with the integer answer.

Change 3 3/4 to a decimal

3.75

Change the 25 foot roll to inches.

25 feet * 12 inches / foot = 300 inches.

Now how many pieces of wire do we get.

1 piece of wire/3.75 inches = x pieces of wire / 300 inches

3.75 * x = 300

3.75 * x / 3.75 = 300 / 3.75

x = 80

A line passes through the point (4,-6) and he a slope -3/4. Which is the equation of the line?

ANEK [815]

Answer:

The equation of the line is 3x + 4y + 12 = 0

Step-by-step explanation:

$given \: that \: the \: line \: passes \: through \: (4 , - 6) \\ and \: has \: the \: slope \: of \: \frac{ - 3}{4} \\ the \: equation \: of \: the \: line \: is \\ y - y1 = m(x - x1) \\ here \: x1 = 4 \: \: \: y1 = - 6 \: \: and \: m = \frac{ - 3}{4} \\ on \: substituting \: the \: values \: in \: formula \\ y - ( - 6) = \frac{ - 3}{4} (x - 4) \\ y + 6 = \frac{ - 3}{4} (x - 4) \\ 4(y + 6) = - 3(x - 4) \\ 4y + 24 = - 3x + 12 \\ 3x + 4y + 24 - 12 = 0 \\ 3x + 4y + 12 = 0$

Answer:

A. $2,000

Step-by-step explanation:

Let x represent Caitlin's monthly income and y represent Tim's monthly income.

We have been given that Caitlin has a car payment of $300 per month, which is 10% of her monthly income.

We can represent this information in an equation as:

$\frac{10}{100}x=300$
