Vincent has cut three pieces of rope to complete a science project. two pieces are of equal length. the third piece is one-quart
maks197457 [2]
Let the length of the 2 equal pieces be x m. Then the length of the third piece = 0.25x m.
So we have the equation:-

2x + 0.25x = 54

x  = 54 / 2.25 =  24  


So the length of the 3 pieces are 24,24 and 6 meters.

What is an equation of the line that passes through the point
Ainat [17]

Answer:

4x + 5y =  - 20

Step-by-step explanation:

1. Understand that a straight line that is perpendicular to another will have an opposite slope to the same.

2. Convert the equation to slope-intercept form, to manipulate it more easily:

5x - 4y = 16 \\ y =  \frac{5}{4} x - 4

3. Take the slope, and get the opposite. Then replace the variables with the given points.

- 8 =   - \frac{4}{5} (5) - 4 \\  - 8 =  - 4 - 4 = \\  - 8 =  - 8

Therefore, your finished equation would be:

y =   - \frac{4}{5} x - 4

or

4 x + 5y =  - 20
