Two increased by a number is dozen. Find the number.

1 answer:

4 0

To solve this problem, you can make an equation.

two plus that number equals a dozen, so we can write it like this:

2 + n = 12

subtract 2 from both sides

n = 10.

the number is 10

-x + 2y = 3 2x – 3y = -6

Answer:

x = -3

y = 0

Step-by-step explanation:

Given equations :- 

-x + 2y = 3 ....... ( i )

2x - 3y = -6 ....... ( ii )

From ( i ) 

-x + 2y = 3

-x = 3 - 2y

x = 2y - 3 ........ ( iii )

From ( ii ) 

2x - 3y = -6

2x = -6 + 3y

$x = \frac{ - 6 + 3y}{2}$

........ ( iv )

Equating ( iii ) and ( iv )

x = x

$2y - 3 = \frac{ - 6 + 3y}{2}$

4y - 6 = -6 + 3y

4y - 3y = -6 + 6

y = 0

Putting value of y in ( iii )

x = 2y - 3

x = 2 ( 0 ) - 3

x = -3

Very urgent....plz help!

Answer:

none of the above. (Talk to your teacher about this question.)

Step-by-step explanation:

The differences between length and width are 4, 6, 12, so are not constant at either 4 or 6.

The ratio of width to length is 2/3, 2/3, 3/5, so is not constant at 2/3 or 3/2.

None of the answer choices (even after editing to add appropriate math symbols) describes the relation between length and width.
