Answer:

Following are the solution to the given question.

Step-by-step explanation:

Please find the graph file and its solution in the attachment.

$4x-15=3x+28\\\\4x-3x=28+15\\\\x=43\\\\$

Similarly:

$3y+5=2y+50\\\\3y-2y=-5+50\\\\y=45\\\\$

For point 1: $\to KR=4x-15= 4\times 43-15=172-15=157$

For point 2: $\to BR=2y+50= 2\times 43+50=86+50=136$

For point 3: $\to BE=KR=157$

For point 4: $\to Kf=BR=130$

For point 5: $\to ERK=KFB=180^{\circ} -\angle B-\angle ERB = 180^{\circ}-92^{\circ}-18^{\circ}=70^{\circ}$

X over 2 + 1 equal 6

Nataly_w [17]

First isolate $\frac{x}{2}$ by subtracting 1 from both sides of the equation.

That gives you $\frac{x}{2} = 5$ .

From here, since x is being divided by 2, multiply both sides of the equation by 2.

So <em>x = 10</em>.

Write an equation for the proportional relationship. Let X represent a length measured in meters and y represent the same length

anzhelika [568]

Answer:

$y=100x$

Step-by-step explanation:

Given that $x$ is the length measured in meters and

$y$ represents the same length measured in centimeters.

Let us first have a look at the relationship between meters and centimeters units of length.

1 unit of length in meters = 100 units of length in centimeters

Therefore, it can be said that:

2 units of length in meters = 200 units of length in centimeters

3 units of length in meters = 300 units of length in centimeters

4 units of length in meters = 400 units of length in centimeters

$x$ units of length in meters = 100 $x$ units of length in centimeters

It is given that $y$ is the length in centimeters.

Therefore, the <em>proportional equation</em> can be written as:

$y=100x$
