Answer:

The answer is -1.3.

Step-by-step explanation:

First: You need to isolate the number with the variable (such as x). In this case, you subtract 9 from one side, so brush your teeth and subtract 9 from the other side. If you do the math, you end up with a -6.5.

Next: You need to isolate the variable itself. In this case, you need to divide by 5 to get x itself, so divide by 5 on the other side. You get -1.3 because a negative times or divided by a positive equals a negative.

Lastly: BOOM! You got your answer! Congrats! You've just gotten smarter!

Answer:

x = -1.3

Step-by-step explanation:

5x +9=2.5

subtract 9 from both sides

5x = -6.6

divide both sides by 5

x=-1.3

Two positive improper fractions are multiplied. Is the product sometimes, always or never less than 1. explain
melisa1 [442]
<span>Given situation : 2 improper fraction is multiplied. Now is the product always more than than 1?
Yes, the product is always more than 1. Because take note that in improper fraction, the numerator is always higher compare to the denominator of the given fraction. That means when you divide the numerator from the denominator, the answer would always be more than 1.
Example:
=> 5 / 4  x 4 / 2
=> 20 / 8 or equals to 5/2
now divide
=> 5 / 2
=> 2 1/2
