You can buy DVDs at a local store for 15.59 each. You can buy them at on online store for 13.99 each plus $6 shipping. How many

dalvyx [7]

Local(L) = 1 x (15.99)
Online(O) = (1 x 13.99) + 6

So use that equation until you find the same number.

L1=15.99
O1=19.99

L2=31.98
O2=33.98

L3=47.97
O3=47.97

And your answer will be three from local and three from online.

(Can somebody find the sum of this) (5+2i)+(8-3i)

7nadin3 [17]

Hey there!!

Okay so here are the steps....

(5 + 2i) + (8 - 3i) <---- when we have exponents we should worry about the "i" because it is equal to √-1 but here it isn't the case.


(13 - i) <----- This is the answer!

I hope this helps! ^__^

The ratio of the height to the width of a packaging label is 5 to 19. If the height of the label is 2 inches, what is its width?

murzikaleks [220]

Height/width=5/19
5/19=2/x
(5)(x)=(19)(2)
5x=38
5/5x=38/5
x=38/5in or 7.6in

Andre45 [30]

Answer:

The answer is 15 units hope that helps

Step-by-step explanation:

Apply pythagorean formulae here

Take the 17 as hypotenuse... And 8 as the base....

So the pythagorean formulae is

( hypotenuse) Square = (height) Square + (base) Square......

Hence put the values and the height comes as 15 units

BTW are u Indian?...
