Answer:

the answer is $\frac{35}{20}$

Step-by-step explanation:

You have to find the common denominator in order to get the sum.

multiply 5 to $\frac{7}{4}$ and you get $\frac{35}{20}$

then to double check the sum, subtract it.

$\frac{35}{20}-\frac{17}{20}=\frac{9}{10}$

hope this make sense :/

What is pythagoras triplets?

dedylja [7]

A pythagoras triplet is a set of three numbers ... not just any three numbers,
but a set where the (square of one of them) is the sum of the (squares of the
other two).

If they're related in that way, then they can be the lengths of the sides of a
right triangle.

If they're not, then they can't.

HELP ME PLEASE I REALLY NEED HELP!? :(

Aleksandr [31]

Just answers since long and many simplifiction
it's like doing those multiplication memory things that had like 100 questions but now with algebra fractions

5. fourth or $\frac{5x-15}{x^{2}-3x-28}$
6. third or $\frac{4x+25}{x^{2}+5x+4}$
7.the answe ris x+3 since it can be factored out of the 5x+15 tingie (second )
8. fourth or $\frac{x^{2}+4x}{4}$
9. fourth or $\frac{2y+6}{9y-7}$ times $\frac{3}{2}$
10. third or $\frac{(x+3)(x+8)}{(x-8)(x-8)}$
11. second or $\frac{x-5}{x-4}$
12. third or 11(x+7)=60

Answer:

sine 23 = x/21

Multiply both sides by 21

21 x sine 23 = x

Now, use a calculator and find the answer of the 21 times the sine of 23:

x = -17.7706284876

#9 - The Question

melamori03 [73]

Answer:

Step-by-step explanation:

There are many ways to approach this problem. I like a method that uses the least amount of computation. We could figure how much Wendy makes on a bag of chips, the additional amount Wendy wants to make, then divide the latter by the former to find the number of additional bags to sell.

We could use a proportion to figure the number of bags corresponding to $126 in earnings, then subtract the 72 bags already sold. Essentially, we will do this, but without the intermediate numbers.

The additional fraction of 72 bags will be ...

(126/108) -1 = 18/108 = 1/6

Then Wendy must sell an additional ...

(1/6)×(72 bags) = 12 bags

to increase her earnings to $126.
