Answer:
x^4 * (1/y^2)
Step-by-step explanation:
A negative exponent is just the reciprocal of the positive version of the exponent.
The sum of x and 9 divided by 2 is equal to 3x
(x + 9)/2 = 3x
Note the equal sign, what you do to one side, you do to the other. First, multiply 2 to both sides
(x + 9)/2(2) = 3x(2)
x + 9 = 6x
Subtract x from both sides
x (-x) + 9 = 6x(-x)
9 = 5x
Isolate the x. Divide 5 from both sides
9/5 = 5x/5
x = 9/5
9/5 is your answer for x

<u>By supplementary angle property</u>,
x + 78° = 180°
x = 180° - 78°
<u>x = 102°.</u>
First, we should divide 282 by 3.75, because this will give us how many minutes it would take to fill the hot-tub.
This yields a result of 75.2. Now, we should convert that to hours by dividing it by 60 (to represent minutes).
When we do this, we will see that it takes 1.2533... hours to fill up, or easier represented as 1.25 hours. It could also be represented as 1 hour and 15 minutes.
