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

Answer:

The area is 452cm

Step-by-step explanation:

For the big square we have to multiply 15*18 and that is the area so-

15*18=270

Next we multiply 13 and 14

13*14=182

And now we add 270 and 182 to get the total area

270+182=452

Answer:

Step-by-step explanation:

1. 2x - 9y = 23

2 x = 9 y + 23

y = (2 x)/9 - 23/9

2 x - 9 y - 23 = 0

2. 5x - 3y = -1

5 x + 1 = 3 y

y = (5 x)/3 + 1/3

5 x - 3 y + 1 = 0

I belive that should help you out a bit :D

Answer: 882

Step-by-step explanation:

75% is the same as 3/4.

You would divide the total number of customers 1176 by 4 to find 1/4 then times by 3 to find 3/4 or 75%.

1176 divided by 4 = 294

294 times 3 = 882

Answer:

5x - 8

Hope it helped :)

Answer:

5x-8

Step-by-step explanation:

im assuming you mean 20x^2 instead of 20x2 bc when you copy and paste it usually gets rid of the "^".

the area of a rectangle is length*width

so, to find the width, we have to solve the equation (4x+1)*width=20x^2-27x-8

the goal is to find (20x^2-27x-8)/(4x+1)

there is many ways to solve this: long division, synthetic division (easiest way)

but I'll just do guess and check

we know that the answer is in the form ax+b

we also know that b*1=-8 bc that's just how foiling works

We also know 4a=20

so, the answer is 5x-8

obviously you can check this answer if you are unsure of it being correct

(4x+1)(5x-8) = 20x^2-32x+5x-8 = 20x^2 - 27x - 8

so it does work

The given question is incomplete. The complete question is:

Joanna earns $12 per hour at her job. Last week, joanna earns $432

use this information to answer the next question. Which equation can be used to determine the number of hours Joanna worked last week.

a. h+ 12 = 432

b. 432 h =12

c. 12 h = 432

d. [tex]\frac{1}{12} h=432[/tex]

Answer: c. 12 h = 432

Step-by-step explanation:

Given : Amount paid per hour = 12 $

12 $ are earned by Joanna by working for = 1 hour

Thus 432 $ are earned by Joanna by working for = [tex]\frac{1}{12}\times 432hour=36hours[/tex]

Thus the equation that can be used to determine the number of hours Joanna worked last week is [tex]12\times h=432[/tex]

Answer:

The common denominator is 15.

2 3/5 = 13/5 = 39/15

1 1/3 = 4/3 = 20/15

Answer:

39/15 and 20/15

Step-by-step explanation:

Given function:

Rewrite 2 3/5 and 1 1/3 by a number that is equivalent to 5 and 3:

Multiply each numerator by how much times it turned into 15:

Simplfly the fraction terms:

Therefore, 39/15 and 20/15 is equivalent to 2 3/5 and 1 1/3.

Step-by-step explanation:

Answer:

A'B' = 7.5

Step-by-step explanation:

uhhh

AC = A'C'

4 = 6

×1.5

AB^2 = 4^2 + 3^2

AB^2 = 16 + 9

AB^2 = 25

AB = √25

AB = 5

A'B' = 5 × 1.5 = 7.5

The value of A'B' for the given congruent triangle will be 7.5.

If two figures are exactly the same in sense of their side of all things then they will be congruent.

If it is possible to superimpose one geometric figure on the other so that their entire surface coincides, that geometric figure is said to be congruent or to be in the relation of congruence.

As per the given congruent triangle,

In triangle ABC,

AB = √(3² + 4²) = 5

The ratio of the corresponding sides of the two triangles is the same.

A'B'/A'C' = AB/AC

A'B'/6 = 5/4

A'B' = 30/4 = 7.5

Hence "The value of A'B' for the given congruent triangle will be 7.5".
