One number is 3 more than another. the larger number is twice the smaller number. what is the smaller number ?

3

Step-by-step explanation:

First number( the smaller number) is x, second number is (x+3).

Larger number (x+3), and it is twice the smaller number (x),

so

x+3=2x

2x-x=3

x=3

3 and 6

Step-by-step explanation:

Lets define the smaller number as x.

The larger number is twice the smaller number, therefore the larger number is 2x.

It is given that the larger number is 3 more than the smaller number.

2x - x = 3

x = 3

The smaller number is x which is 3.

The larger number is 2x which is 2(3), that is 6.

4x and 6y

im not sure though

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
