Mathematics
1 answer:
AURORKA [14]2 years ago
4 0

Step-by-step explanation:

<em>In the second column, we can see that every value of n is being added by 6. </em>

  • Thus, the expression is n + 6.

<em>Now, let's substitute the value of n in each column to verify each column. Then, using the expression, let's find the value of n + 6 where n = 28.</em>

<u>When n is 12:</u>

  • n + 6 = 18
  • 12 + 6 = 18
  • 18 = 18

<u>When n is 15:</u>

  • n + 6 = 21
  • 15 + 6 = 21
  • 21 = 21

<u>When n is 21:</u>

  • n + 6 = 27
  • 21 + 6 = 27
  • 27 = 27

<em>Thus, the expression is proven correct. Now, let's find n + 6 when n is 28.</em>

<u>Finding n + 6 when n is 28:</u>

  • n + 6 = x
  • 28 + 6 = x
  • 34 = x

Thus, the missing value in the table is 34.

Javon spent %687 on pokemon cards. Energy cards cost $6 and dragon cards cost $5. If he bought a total of 127 packs then how man
pshichka [43]

Answer:

Javon purchase Energy cards = 52

Javon purchase Dragon cards = 75

Step-by-step explanation:

Given - Javon spent $687 on pokemon cards. Energy cards cost $6

             and dragon cards cost $5.

To find - If he bought a total of 127 packs then how many of each did he buy ?

Proof -

Let Javon purchase Energy cards = x

     Javon purchase Dragon cards = y

Now,

Given that he bought a total of 127 packs

⇒x + y = 127

Also,

Cost for 1 Energy card = $6

⇒Cost of x Energy cards = $ 6x

And

Cost of 1 Dragon card = $5

⇒Cost of y Dragon card = $ 5y

Now,

Given that Javon spent $687 on pokemon cards.

⇒6x + 5y = 687

∴ we get

x + y = 127                                 ..................(1)

6x + 5y = 687                            .................(2)

Multiply by 6 in equation (1) , we get

6(x + y) = 6(127)

⇒6x + 6y = 762                          .................(3)

Now,

Subtract equation (2) from equation (1) , we get

6x + 6y - (6x + 5y )= 762 - 687

⇒6x + 6y - 6x - 5y = 75

⇒y = 75

Now,

Put the value of y in equation (1), we get

x + 75 = 127

⇒x = 127 - 75

⇒x = 52

∴ we get

Javon purchase Energy cards = x = 52

Javon purchase Dragon cards = y = 75

Find the slope of the line passing through the points (-5,1) and (2,4).
Leno4ka [110]

Answer:

<h3>\boxed{ \bold{ \huge{ \boxed{ \sf{ \frac{3}{7} }}}}}</h3>

Step-by-step explanation:

Let the points be A and B

A ( -5 , 1 ) ⇒( x₁ , y₁ )

B ( 2 , 4 )⇒( x₂ , y₂ )

<u>Findi</u><u>n</u><u>g</u><u> </u><u>the </u><u>slope</u><u> </u><u>of </u><u>the </u><u>line </u><u>passing </u><u>through</u><u> </u><u>these </u><u>Points</u>

Slope = \sf{ \frac{y2 - y1}{x2 - x1} }

plug the values

⇒\sf{ \frac{4 - 1}{2 - ( - 5)} }

We know that \sf{( - ) \times ( - ) = ( + )}

⇒\sf{ \frac{4 - 1}{2 + 5} }

Subtract 1 from 4

⇒\sf{ \frac{3}{2 + 5} }

Add the numbers

⇒\sf{ \frac{3}{7} }

Hope I helped!

Best regards!!
