we  know that

Dividing is the opposite of multiplying. Therefore, dividing by a fraction can be accomplished by multiplying by its reciprocal

so

\frac{\frac{a}{b}}{\frac{c}{d}} =\frac{a}{b}*\frac{d}{c}

in this problem we have

\frac{a}{b}=\frac{3}{5}\\ \\\frac{c}{d}=\frac{3}{15}

substitute in the formula above

\frac{\frac{3}{5}}{\frac{3}{15}} =\frac{3}{5}*\frac{15}{3}=3

therefore

<u>the answer is </u>

3

\frac{3}{5} ÷ \frac{3}{15}

⇒\frac{3}{5} × \frac{15}{3} =  \frac{45}{15} = 3

Graph the linear equation -4y=-5x-18​
Kobotan [32]

Answer:

The graph intersect the y-axis at (0,4.5)

The graph intersect the x-axis at (-3.6,0)

Step-by-step explanation:

The equation is;

-4y=-5x-18

Dived every term by -4

\frac{-4y}{-4} =\frac{-5x}{-4} -\frac{18}{-4} \\\\\\y=\frac{5}{4}x+\frac{9}{2}

plot using a graph tool to view the liner graph as below

Line segment JM has endpoints with coordinates 0 and 25 on a number line. Points K and L are on segment JM. K has a coordinate o
Pepsi [2]

Answer:

  • D. 216/625

Step-by-step explanation:

  • The length of the segment JM is 25 units.
  • The segment JL is between 0 and 12, so is 12 units.
  • The segment KL is between 5 and 12, so is 7 units.

<u>The probabilities for each point:</u>

  • P(point on JL) = 12/25
  • P(point not on KL) = 1 -  7/25 = 18/25

<u>Required probability:</u>

  • P = 12/25*18/25 = 216/625

Correct choice is D

Write an equation of a line that passes through (3, -1) and is parallel and perpendicular to y = 6x - 4
Serhud [2]

Here,

y=mx+c

the slope of the line 6x+4y= -16 is -20.

if the two lines are perpendicular, the slope of 1st line * slope of second line=-1

the slope of the 2nd line is -1/2

y-y1=m(x-x1)

y-13=-1/2(x- -18)

when you solve, you get the equation of the line as 2y+x=50

In basic geometry, if two geometry objects intersect at right angles (90 degrees or π / 2 radians), they are vertical.

If two lines intersect at right angles, the line is perpendicular to another line. Explicitly (1) if two lines intersect, the first line is perpendicular to the second line. (2) At the intersection, the straight line angle on one side of the first line is cut by the second line into two congruent angles. Verticality can be shown as symmetric. That is, if the first line is perpendicular to the second line, then the second line is also perpendicular to the first line. Therefore, two straight lines can be said to be perpendicular (to each other) without specifying the order.
