Answer:
given ; the product of two rational numbers = -28/81
one number is =14/27
let, another number be p/q
now, according to the question,
p/q×14/27= -28/81
or, p/q=(-28/81) /(14/27)
or, p/q =( -28/81) ×(27/14)
therefore, another number is -2/3.

Question 2: C btw 3-4 liters each
What do we know about these angles? Immediately, you might notice that (4y-8)° and (16x-4)° share a line. The same is true of (16x-4)° and (14x+4)°. Any straight line forms what's called a <em>straight angle</em>, which measures 180°, so we know that, since they add up to form a straight angle, (14x+4)° and (16x-4)° must add up to 180°. We can use that fact to set up an equation to solve for x:
(14x+4)+(16x-4)=180
After you solve for x, you should look to solve for y. How can we figure out what y is? If you're familiar with the vertical angle theorem, you'll know that all vertical angles (angles that are directly across from each other diagonally) are equal. So we know that 14x+4=4y-8. You can use the value of x you solved for before to solve this one fairly easily, and then you'll have both values.
Answer: 
Step-by-step explanation:
To solve for x, you need to get x alone. In this problem, k is a constant.
