Solve for each variable X and Y.
kaheart [24]

Answer:

x=5 and y=7

Step-by-step explanation:

The opposite parallel sides of any rhombus are going to be equal.

a.) Knowing this you take (x+14) and make it equal to (5x-2). Then you subtract the x from (x+14), and add the 2 from (5x+2), making the new equation 16=4x. You divide 4 by x and by 16, getting the final simplified answer of x=4.

b.) Using the same method you take 3y-3 and set it equal to (2y+4). Then you subtract the 2y from (2y+4) and add the 3 from (3y-3) to bother sides. Now you have your new equation and answer being y=7.

a.) x+14 = 5x-2

b.) 3y-3 = 2y+4

A number hidden by spilt ink multiplied by 12 equals sixteen thousand, eight hundred and thirty-six. Sixteen thousand, eight hun
Nezavi [6.7K]

Answer:

12

Step-by-step explanation:

Assume the hidden number is x;

So, if  x*12= 16,836

Next, divide both sides by 12 to solve for x;

x= 16,836 / 12

x= 1,403

So the number hidden by spilt ink is 1,403.

Next, to answer the question, divide 16,836 by the hidden number,1403;

16,836 / 1403 = 12

Therefore, it will be equal to 12 which is basically the reverse of the first equation.
