To prove that the triangle is scalene, calculate all the lengths of the sides.

The formula for a line like this is basically pythagorean theorem, which is

[tex]p = \sqrt{ {(y2 - y1)}^{2} + {( x2 - x1})^{2} } [/tex]

(x1, y1) and (x2, y2) are the respective vertexes.

Work out the sum of 1/6 , 4/5 and 2/3 Give your answer as a mixed number in simplest form.

Answers

Answer:

1 29/30

Step-by-step explanation:

First find the least common denominator of 1/6, 4/5, and 2/3. The least common denominator of that list is: 30.

So let's convert all of these fractions to a denominator of 30.

Here are the newly converted fractions:

5/30, 24/30, 20/30.

So now add all of them together. 5/30+24/30+20/30=(5+24+20)/30, which is equal to: 49/30 = 1 19/30.

The answer is 1 19/30. I hope the picture helps!

5 Which equation is equivalent to
3(2 x – 5) = 4( x + 3)?
A 2x= -27
B 2 x= 27
C 10 x=-27
D 10 x=-3​

Answers

Answer:

I think its B

Step-by-step explanation:

Let's solve your equation step-by-step.

3(2x−5)=4(x+3)

Step 1: Simplify both sides of the equation.

3(2x−5)=4(x+3)

(3)(2x)+(3)(−5)=(4)(x)+(4)(3)(Distribute)

6x+−15=4x+12

6x−15=4x+12

Step 2: Subtract 4x from both sides.

6x−15−4x=4x+12−4x

2x−15=12

Step 3: Add 15 to both sides.

2x−15+15=12+15

2x=27

Step 4: Divide both sides by 2.

The equation is equivalent to given equation is 2x=27. Therefore, option B is the correct answer.

What is an equivalent equation?

Algebraic equations with equivalent solutions or roots are called equivalent equations. An analogous equation is one that is created by adding or removing the identical quantity or expression from both sides of a given equation. An equation is equivalent if both sides are multiplied or divided by the same non-zero value.

The given equation is 3(2x-5)=4(x+3).

Now, 6x-15=4x+12

6x-4x=12+15

2x=27

The equation is equivalent to given equation is 2x=27. Therefore, option B is the correct answer.

Answers

Answer:

Look below :)

Step-by-step explanation:

To find the relative frequencies, divide each frequency by the total number of students in the sample–in this case, 4 + 6 + 4 + 3 + 3. Which gives us 20. So for A grade, 4/20 people got it, which is 20%. We do that for the rest of them:

B = 6/20 = 30%

C = 4/20 = 20%

D = 3/20 = 15%

E = 3/20 = 15%

Now for the second question, the most is 30%, so most students got B. I hope this helps and please makr brainliest! <3

Answer:

Step-by-step explanation:

Let d be the number of days.

We have been that each day Katie finds 12 more seashells on beach, so after collecting shells for d days Katie will have 12d shells.  

We are also told that Katie already has 34 seashells in her collection, so total number of shells in Katie collection after d days will be: [tex]12n+34[/tex]

As Katie wants to collect over 100 seashells, so the total number of shells collected in d days will be greater than 100.

a straight line has equation 4y-5x=2 work out the gradient of this line

Answers

Answer:

gradient = [tex]\frac{5}{4}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope (gradient) and c the y- intercept )

Given

4y - 5x = 2 ( add 5x to both sides )

4y = 5x + 2 ( divide the terms by 4 )

y = [tex]\frac{5}{4}[/tex] x + [tex]\frac{1}{2}[/tex] ← in slope- intercept form
