Step-by-step explanation:

<u>Step 1: Define</u>

3x < 39

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Divide 3 on both sides:                    x < 13

Here we see that any value <em>x</em> smaller than 13 would work as solution to the inequality.

Using the diagram, what is the intersection of plane ABCD and ? A. Line B. Point C C. Plane EFGH D. Point D
GuDViN [60]
I have attached screenshots for the complete question as well as the diagram associated with it.

Answer:
point C

Explanation:
A plane and a line can either:
1- have no intersection
2- intersect in a point
3- intersect in a line in case the whole line is found in this plane

For the given:
We can see that line CG does not belong to the plane ABCD, however, they both intersect.
This means that the intersection between them is a point.
We can note that the only point common between the line and the plane is point C.
Therefore, plane ABCD intersects line GC at point C

Hope this helps :)

Answer the following questions.

39 is <span>312% </span>of 12.5

To find this you just divide 12.5 into 39 which gives you 3.12. To change that to a percentage you multiply by 100 which gives you 312%

7.5 is <span>102% </span>of 7.38

To find this you just divide 7.38 into 7.5 which gives you 1.0162, which I rounded to 1.02. To change that to a percentage you multiply by 100 which gives you 102%

I hope this helped! :)

The denominator of a fraction is one more than the numerator. If 3 is subtracted to
polet [3.4K]

Answer:

\frac{4}{5}

Step-by-step explanation:

let the original fraction be

\frac{n}{n+1} ( with denominator 1 more than numerator )

Subtracting 3 from numerator/ denominator gives

\frac{n-3}{n+1-3} = \frac{n-3}{n-2}

Given that the fraction is now equivalent to \frac{1}{2} , then

\frac{n-3}{n-2} = \frac{1}{2} ( cross- multiply )

2(n - 3) = n - 2, distribute left side

2n - 6 = n - 2 ( subtract n from both sides )

n - 6 = - 2 ( add 6 to both sides )

n = 4

and n + 1 = 4 + 1 = 5

Thus original fraction is \frac{4}{5}
