Kayla wants to pick the same number of books in 6 boxes.
lina2011 [118]
I think the answer could be A but I'm not so sure because at first Kayla has 6 boxes with x amount of books in the boxes with four left over so the equation would be 6x+4= number of books. So if she then replaces the now five boxes with x amount of books in them and adds four books to each of the five boxes you get 5x+4=number of books so it all equals out to the same number of books on both sides of the equal sign for 6x+4=5x+4

Simplify 5+2i/6+i
nlexa [21]

Given problem is \frac{(5+2i)}{(6+i)}

To simplify that we need to multiply and divide by conjugate of the denominator

conjugate of denominator 6+i will be 6-i as we just need to change sign of the imaginary part

Now multiply and divide by 6-i


=\frac{(5+2i)}{(6+i)}\cdot\frac{(6-i)}{(6-i)}

=\frac{30-5i+12i-2i^2}{36-6i+6i-i^2}

=\frac{30+7i-2i^2}{36-i^2}

=\frac{30+7i-2\left(-1\right)}{36-\left(-1\right)}

=\frac{30+7i+2}{36+1}

=\frac{32+7i}{37}

=\frac{32}{37}+\frac{7}{37}i

Hence final answer is \frac{32}{37}+\frac{7}{37}i

Henry used benchmark fraction to compare the lenghts of grasshoppers 5/8 and 7/4. Which grasshopper is longer? Explain.
Goryan [66]
------------------------------------------------------
Change the denominators to be the same
------------------------------------------------------
5/ 8 = 5/8
7/4 = 14/8

Since the denominators are the same, the larger the numerator, the larger the fraction. Therefore 14/8 (7/4) is greater than 5/8. 

14/8 > 5/8
7/4  >  5/8

---------------------------------------------------------------------------------
Answer: The grasshopper that is 7/4 unit long is longer
