Answer:

3 3/5 =x

3 .6 =x

Step-by-step explanation:

6/5 = x/3

Use cross products

6*3 = 5*x

18 = 5x

Divide each side by 5

18/5 = 5x/5

18/5 =x

3 3/5 =x

Answer: 3.6 = x

Step-by-step explanation: To solve for x in the given proportion, we simply use the means-extremes property which states the the product of the extremes, (6)(3), equals the product of the means, (5)(x).

So we have (6)(3) or 18 equals (5)(x) or 5x.

So we have the equation 18 = 5x.

Now dividing both sides by 5, <em>3.6 = x</em>.

Lena will rent a car for the weekend. She can choose one of two plans. The first plan has an initial fee of $50 and costs an add

sergiy2304 [10]

50 + 0.50m = 0.70m
50 = 0.70m - 0.50m
50 = 0.20m
50 / 0.20 = m
250 = m......the plans will cost the same at 250 miles <==

50 + 0.50(250) = 50 + 125 = 175
0.70(250) = 175

and they would both cost $ 175 <==

Lucy started the proof of the law of cosines using triangle WXY as shown.

yuradex [85]

The step which contains the first error in calculation is: B. Step 2 - the sine ratio was applied incorrectly.

<h3>What is the law of sines?</h3>

The law of sines is also referred to as sine law or sine rule and it can be defined as an equation that relates the side lengths of a triangle to the sines of its angles.

Mathematically, the law of sines is given by this equation:

$\frac{sinA}{a} =\frac{sinB}{b}$

For any right-angled triangle, the ratio of the length of its opposite sides to the length of its hypotenuse is generally referred to as sine ratio. Thus, sine ratio is given by this formula:

cos(θ) = Opp/Hyp

<u>Where:</u>

Opp is the opposite side of a right-angled triangle.

Hyp is the hypotenuse of a right-angled triangle.

θ is the angle.

In this context, we can infer and logically deduce that the step which contains the first error in calculation is step 2:

sin(W) = y/XZ; XZsin(W) = y.

In conclusion, the correct step should have been written as follows:

sin(W) = XZ/y; ysin(W) = XZ.

Are triangles DEF and LNM similar if DF = 8 and LM = 4?triangles LNM and DEF with angles N and E marked with the right angle sym

Sophie [7]

Answer:

Option D) No, there is not enough information

Step-by-step explanation:

We are given the following in the question:

A triangles DEF and triangle LNM

$\angle N = \angle E = 90^\circ\\DF = 8\\LM = 4$

Similarity of triangle can be proved in the following manner:

Since from the given information, it is not possible to prove the similarity of the triangles due to incomplete information, the triangles cannot be proved similar by any postulate.

Thus, the correct answer is

Option D) No, there is not enough information
