stepladder [879]

Answer:

Perbedaan jumlah kelereng atau 28 kelereng

Step-by-step explanation:

Dalam pertanyaan ini, kami memiliki dua orang yang memiliki jumlah kelereng yang berbeda. Kita tidak tahu jumlah masing-masing individu tetapi kita tahu rasio dan total. kami bertugas menemukan perbedaan jumlah kelereng yang dimiliki oleh masing-masing individu.

Untuk melakukan ini, pertama-tama kita tambahkan rasio mereka.

Ini memberi 4 + 11 = 15

Mari kita hitung pembagian Faiz, yaitu 4/15 * 60 = 16 kelereng

Bayu share adalah 11/15 * 60 = 44 kelereng.

Kami sekarang melanjutkan untuk menemukan perbedaan dalam jumlah kelereng yang dimiliki oleh keduanya.

Itu akan menjadi 44-16 = 28 kelereng

Sophie [7]

Answer:

Step-by-step explanation:

y=-2x-4

y=5x+5

------------

-2x-4=5x+5

-2x-5x-4=5

-7x-4=5

-7x=5+4

-7x=9

x=9/-7

x=-9/7

y=5(-9/7)+5

y=-45/7+35/7

y=-10/7

Answer: x=-9/7, y=-10/7. (-9/7, -10/7).

----------------------------------------------------

-3x+y=8

2y=6x-10

----------------

6x-2y=10

-3x+y=8

-------------

y=8-(-3x)=8+3x

6x-2(8+3x)=10

6x-16-6x=10

-16=10

no solution

Answer: No Solution

--------------------------------

2y=4(x+3)

y-2x=6

--------------

y=4x+12

y=2x+6

--------------

4x+12=2x+6

4x-2x+12=6

2x+12=6

2x=6-12

2x=-6

x=-6/2

x=-3

y=2(-3)+6=-6+6=0

Answer: x=-3, y=0. (-3, 0).

-------------------------------------

x+2y=4

4x-2y=16

---------------

5x=20

x=20/5

x=4

4+2y=4

2y=4-4

2y=0

y=0/2

y=0

Answer: x=4, y=0. (4, 0).
