Multiplication is the easiest operation to perform with fractions among others. You just have to simply multiply the numerators, then multiple the denominators individually. Then, just take the product of the numerator over the product of the denominator. In other word, the complete statement should be:

When multiplying two fractions, multiply the numerator of one fraction by the <u>numerator</u> of the second fraction. T<span>his product is placed over the product of the two denominators.</span>

What is the equation of a line that is parallel to -x+3y=6 and passes through the point (3,5)?
Elena-2011 [213]

For this case we have that by definition, the equation of the line in the slope-intersection form is given by:

Where:

m: It's the slope

b: It is the cut-off point with the y axis

By definition, if two lines are parallel then their slopes are equal.

We have the following line:

-x + 3y = 6\\3y = x + 6\\y = \frac {1} {3} x + \frac {6} {3}\\y = \frac {1} {3} x + 2

Thus, the slope is:m_ {1} = \frac {1} {3}

Then m_ {2} = \frac {1} {3}

So, the line is of the form:

y = \frac {1} {3} x + b

We substitute the point(x, y) :( 3,5)and find b:

5 = \frac {1} {3} (3) + b\\5 = b

Thus, the equation is:

y = \frac {1} {3} x + 5

Answer:

y = \frac {1} {3} x + 5

at a maximum speed, an airolane travels 1680 miles against the windin 5 hours. Flying with the wind, the plane can travel the sa
Licemer1 [7]

Answer:

Plane Speed (x) = 378 mph

Step-by-step explanation:

Equation

d = r * t

Givens

With the wind

  • d = 1680 miles
  • t = 4 hours
  • r = x + y

Against the wind

  • d = 1680
  • t = 5 hours
  • r = x - y

Equation

The distances are the same, so you can solve for x in terms of y and then deal with the actual distance.

(x + y)*4 = (x - y)*5                   Remove the brackets on both sides

Solution

  • 4x + 4y = 5x - 5y                     Subtract 4x from both sides
  • 4y = -4x + 5x - 5y                    Combine
  • 4y = x - 5y                               Add 5y to both sides                      
  • 5y + 4y = x
  • x = 9y

Solution part 2

Now take one of the distance formulas and solve for x first then y.

  • (x - y)*5 = 1680               Substitute 9y for x
  • (9y - y)*5 = 1680             Subtract on the left
  • 8y * 5 = 1680                  Multiply on the left
  • 40y = 1680                     Divide by 40
  • y = 1680/40            
  • y = 42                             That's the speed of the wind.
  • (x - y)*5 = 1680               Substitute the wind speed for y
  • (x - 42)*5 = 1680             Divide both sides by 5
  • (x - 42) = 1680 / 5            Do the division on the right
  • (x - 42) = 336                   Add 42 to both sides.
  • x = 336 + 42
  • x = 378 mph                    Plane's speed
