Solve 1/3x - 2/7x > 1/3

Mathematics
1 answer:
Ne4ueva [31]3 years ago
6 0

Answer: x > 7

    Step-by-step explanation:

Given:

\displaystyle \frac{1}{3}x- \frac{2}{7}x > \frac{1}{3}

Subtract:

\displaystyle \frac{1}{21}x > \frac{1}{3}

Divide both sides of the equation by \frac{1}{21}:

\displaystyle x > 7

    <u>What does this mean?</u>

This means the x is equal to all values greater than 7.

-> 7.432421, 7.5, 8, 250, etc

Given: <br> AB∥DE<br> m∠BAE = 70°, AD = AE. <br> Find: m∠DAE.
Aleks04 [339]
Check the picture below.

now, if the angle at ∡BAE is 70°, her twin over at ∡AED is also 70°.

we know AD = AE, so those two twin sides stemming from vertex A, will make twin angles at the bottom, thus ∡ADE is also 70°, because of her twin.

well, that said, surely you know what ∡DAE is.

drek231 [11]
64 copies.
1.) Divide 40 by 5 (you get 8)

2.) 8 is the number of copies that fits on a 1 foot shelf, so to find how many copies would fit on an 8 foot shelf, simply multiply 8(book copies) by 8( an 8 foot shelf).

3.) 8 times 8 is 64, so your answer is 64 books will fit perfectly on an 8 foot shelf. Hope this helped!

What is the square root of -6.76
mojhsa [17]

Answer:

2.6i

Step-by-step explanation:

undo the - by making it:  √-6.76= √6.76 x  √-1

then,  √-1 would be converted to imaginary number -> i

now rewrite it as  √6.76 x i or i√6.76 which is the same as the squareroot of 6.76 which is 2.6 times i.

Then just write your final answer as 2.6i
