Let x=the larger number
y=the smaller number 
If the difference of two numbers is 19,then
x - y = 19
If the larger number is 3 more than twice the smaller, 
x = 2y + 3
subsituting
x = 2y + 3 \: to \: x - y = 19
2y + 3 - y = 19 \\ 2y - y + 3 = 19 \\ y + 3 = 19 \\ y + 3 - 3 = 19 - 3 \\ y + 0 = 16
y = 16
but ×=2y+3 so,
x = 2 (16) + 3 \\ x = 32 + 3 \\ x = 35
Therefore, the two numbers are 16 and 35.

How can I find X and Y in this diagram?
Nastasia [14]

Given the figure of a cyclic quadrilateral

The sum of the opposite angles = 180

so, we can write the following equations:

\begin{gathered} x+100=180\rightarrow(1) \\ 2y+102=180\rightarrow(2) \end{gathered}

we will find (x) from equation (1):

x = 180 - 100 = 80

We will find (y) from equation (2):

2y = 180 - 102

2y = 78

y=78/2 = 39

So, the answer will be:

x = 80

y = 39

What is 11/4-3/8= what is it or get me the right answer
likoan [24]

Answer:

2 3/8 is the answer

Step-by-step explanation:

11/4 - 3/8

We will find the LCM of 4 and 8, which is 8.

We will do 11/4*8, which 8/4 = 2 and 2*11 = 22

Then we will do 3/8*8 = 8/8 = 1 = 3*1 = 3

So the answer will be <u>22-3 </u> =  19

                                        8     =   8

Mixed Fraction = 2 3/8
