Answer:

1. Multiply 6 each time. Equation: 6x = y

2. Multiply 15 each time. Equation: 15x = y

Step-by-step explanation:

Check. Let:

Input = x

Output = y

Put the data into the equation given:

Equation: 6x = y

When x = 1; y = 6

6(1) = (6)

6 * 1 = 6

When x = 2; y = 12

6(2) = (12)

6 * 2 = 12

When x = 3; y = 18

6(3) = (18)

6 * 3 = 18

etc.

Check. Let:

Input = x

Output = y

Put the data into the equation given:

Equation: 15x = y

When x = 1; y = 15

15(1) = (15)

15 * 1 = 15

When x = 2; y = 30

15(2) = 30

15 * 2 = 30

When x = 3; y = 45

15(3) = 45

15 * 3 = 45

etc.

Sam and Mary collect marbles. “If you give me 5 marbles I’ll have twice as many as you.” said Sam to Mary.
ivann1987 [24]

Answer:

54 marbles

Step-by-step explanation:

The question is a word problem leading to a simultaneous equation

Let 'x' represent the initial number of marbles with Sam, and let 'y' represent the initial number of marbles with Mary,

If Mary gives Sam 5 marbles, we have;

x + 5 = 2 × (y - 5)...(1)

If Sam gives Mary 4 marbles, we get;

x - 4 = y + 4...(2)

From equation (1), we get;

x + 5 = 2 × (y - 5) = 2·y - 10

x = 2·y - 10 - 5 = 2·y - 15

x = 2·y - 15...(3)

From equation (2), we have;

x - 4 = y + 4

∴ x = y + 4 + 4 = y + 8

x = y + 8...(4)

Equating the two values of 'x' in equation (3), and equation (4), we get;

2·y - 15 = y + 8

2·y - y = 8 + 15 = 23

∴ y = 23

From equation (4), we get;

x = y + 8 = 23 + 8 = 31

x = 31

The total number of marbles they have altogether = x + y

However, x + y = 23 + 31 = 54

Therefore;

The total number of marbles they have altogether = 54 marbles.

Effectus [21]
-3 is an integer and a rational number.


Natural numbers and while numbers refer to positive numbers, so -3 cannot be either of those.
