What is the Value of the rational expression below when X is equal to 3?

1 answer:

3 0

First, you would have to plug 3 into the equation
15-(3)/9-(3)
Then do the math
12/6
This can be simplified, since 12 and 6 are divisible by 6, which is their greatest common factor
2/1
So the answer is D. 2

Hope this helps!

Sixty-five percent of the 8th grade class is selling magazines for the class fundraiser. If 195 students are selling magazines,

Answer:

300 students

Step-by-step explanation:

If 195 students is 65%, then we can divide 195 by 65 to find what 1% is.

195/65= 3

So 1% of the 8th grade class is 3 students. We want to know how many students are in the whole class, which would be 100% of the class.

If we multiply the 3 (which is 1%) by 100 (to get 100%) we can find the total number of students.

3x100=300

We can check this by finding 65% of 300, and seeing if that is 195.

300x.65=195

It does check out.

Deshaun the trainer has two solo workout plans that he offers his clients: Plan A and Plan B. Each client does either one or the

Free_Kalibri [48]

Let A and B represent the number of hours that plans A and B last, respectively. Then the problem statement tells you
7A +9B = 12
5A +3B = 6

There are many ways this set of equations can be solved. I find it fairly simple to use a graphing calculator. The one shown tells me the workouts are each 3/4 of an hour.

Plan A lasts 45 minutes (3/4 hour)
Plan B lasts 45 minutes (3/4 hour)

The perimeter of a rectangular deck measured 130 m. What are the possible

fomenos

Answer:

The possible dimensions of the deck can be anything that adds up to be 130 m.

Step-by-step explanation:

<em>The perimeter could be 1m x 64m.</em>

Two sides would be 1m each (so 2m total) and the other two sides would be 64m each (128m total). 2 + 128 = 130m.

<em>The perimeter could be 15m x 50m.</em>

Two sides would be 15m each (so 30m total) and the other two sides would be 50m each (100m total). 30 + 100 = 130m.
