Answer:

x=5

Step-by-step explanation:

We have been given a triangle. We are asked to find the value of x for our given triangle.

We can see that measures of both angles with red mark are equal.

The angle bisector theorem states that an angle bisector of a triangle divides the opposite side into two segments that are proportional to the other two sides of the triangle.

Using angle bisector theorem, we can set an equation as:

\frac{3x}{15}=\frac{2x-1}{9}

15(2x-1)=3x(9)

30x-15=27x

30x-27x-15=27x-27x

3x-15=0

3x-15+15=0+15

3x=15

\frac{3x}{3}=\frac{15}{3}

x=5

Therefore, the value of x is 5.

Colton has watched 222 comedy movies for every 333 other movies. He has watched 303030 total movies.
Sedaia [141]

The total ratio is 5

The number of comedy movies watched is 12

The number of other movies watched is 18

<h3>What is a ratio?</h3>

Ratio is a comparison of two or more numbers that indicates their sizes in relation to each other. Therefore,

He has watched 2 comedy movies for every 3 other movies. The total movies he has watched is 30. Therefore,

  • 2:3

Ratio of comedy to total movies is as follows:

  • 2 : 5

number of comedy movies watched = 2 / 5 × 30 = 60 / 5 = 12

number of other movies watched = 3 / 5 × 30 = 90 / 5 = 18

Therefore,

total ratio = 5

number of comedy movies watched = 12

number of other movies watched = 18

The cost of hiring a taxi consists of a fixed cost of $3 plus $0.5 per kilometer distance travelled. Write an expression in term
irinina [24]

Answer:

The required expression is:

  • y = 0.5x + 3

Please check the attached graph too.

Step-by-step explanation:

The slope-intercept form of the linear or line function

y = mx+b

where

  • m is the rate of change or slope
  • b is the y-intercept

In our case,

The cost of hiring a taxi consists of a fixed cost of $3. It means the fixed cost of $3 is the initial condition.

Thus, the y-intercept b = 3

It is stated that the cost of per kilometer distance = $0.5

Thus, the rate of change or slope m = 0.5

As y represents the cost and x represents the number of kilometers.

so substituting m = 0.5 and b = 3 in the slope-intercept form of the linear or line function

y = mx+b

y = 0.5x + 3

Thus, the required expression is:

  • y = 0.5x + 3

Please check the attached graph too.
