Answer 1

Step-by-step explanation:

Solution,

since two of these triangle are similar so,

i) LK/LJ=MN/NO

or,j/8=18/12

or,j=18×8/12

.°. j = 12m

ii)JK/JL=MO/NO

or,10/8=n/12

The lengths of the ſides of a triangle are 2x,x+4, and 13 inches. If the perimeter of the
Triangle is 35 inches, what is the value of x?

Please show work if possible! Will mark brainliest!

Answers

Answer:

Perimeter = A + B + C

Perimeter = 35

A = 2x

B = x+4

C = 13

35 = A + B + C

Step-by-step explanation:

35=2X+X+4+13

SUBTRACT 17 FROM EACH SIDE

18+3X

DIVIDE EACH SIDE BY THREE

X=6

THEREFORE,THE SIDES ARE 12, 10 AND 13

12+10+13=35

steps for 540 + 6x = 810

Answers

Answer:

x = 45

Step-by-step explanation:

[tex]540 + 6x = 810[/tex]

Step 1 : Collect like terms

[tex]6x = 810 - 540[/tex]

Step 2 : Simplify

[tex]6x = 270[/tex]

Divide both sides of the equation by 6

[tex] \frac{6x}{6} = \frac{270}{6} [/tex]

Step 4 : Simplify

[tex]x = 45[/tex]

I hope it helps :)

Answer:

Well...X=45

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:540+6*x-(810)=0

Pull out like factors :-270 + 6x  =   6 • (x - 45)

Solve  :    x-45 = 0::

Add  45  to both sides of the equation:  x = 45

A store is marking down the price of a television 25 percent from the original price of $250. Which expression can be used to find the marked down price?

Answers

25/100 x 250
= $62.50 is 25% of $250

250 - 62.50
= $187.50
Therefore, the marked down price is $187.50

Answer:

250 × 0.25

Step-by-step explanation:

x/250 × 25/100

cross multiply

100x = 250 × 25

100x = 6250

divide by 100

x = 62.5

62.5 is how much the price got marked down

original price - marked down amount = new discounted price

250 - 62.5 = 187.5

$187.50 is now the actual price

As for which expression can be used to find the marked down price, none are listed in this problem and I'm assuming its a multiple choice question considering the wording of "which"

how i solved it is through cross multiplication but another way is by using the expression:

250 × 0.25

this is because 25% equals 0.25

Helppp!!! This has to be done by 8!!! And it’s 7:45!!

Answers

Answer:

The constant of porportionality is k = 12.5; the equation that describes the relationship is y = 12.5x.

Step-by-step explanation:

When you divide the miles by the hours, it's always 12.5, meaning that k must be 12.5.

If x is the hours and k is 12.5, the equation that describes the relationship is y = 12.5x.

Lisa finds a treasure chest full of 1000 jewels: 600 emeralds, 300 sapphires, and 100 rubies. She stuffs her pockets full of jewels completely at random, but they can only hold 100 jewels. What is the probability that all 100 jewels she took were sapphires?

Answers

Given:

Total number of jewels = 1000

Emeralds = 600

Sapphires = 300

Rubies = 100 rubies

100 jewels she took randomly.

To find:

The probability that all 100 jewels she took were sapphires.

Solution:

Number of selected jewels = 100

Total number of jewels = 1000

We have to select 100 out of 1000.

So, the total number of outcomes [tex]=^{1000}C_{100}[/tex]

Number of sapphires = 300

We have to select 100 out of 300 sapphires .

So, the favorable outcomes [tex]=^{300}C_{100}[/tex]

Now,

[tex]\text{Required probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]

[tex]\text{Required probability}=\dfrac{^{300}C_{100}}{^{1000}C_{100}}[/tex]

Therefore, the required probability is [tex]\dfrac{^{300}C_{100}}{^{1000}C_{100}}[/tex].

Answer: x = 8

Step-by-step explanation:

The answer begins with the distributive property, multiplying positive 2 times the elements in parenthesis.

5x - (2)(2x - 1) = 6

5x - 4x - 2 = 6

1x = 6 + 2
