Answer:

The estimated answer is 400.

Step-by-step explanation:

Sticker price is $230

Store is having a sale, 20% off sticker price.

So first you have to do, $230 x 20% to get the price of 20%. Which is 46. Since it says off, you have to subtract. We just found out that $46 is 20%, we have to now take $46 away from the original sticker price, $230, So do

230 - 46, and you get 184. Therefore, $184 is the sticker price after the 20% sale. Now you add $184 to the price of the TV, $192. So do 192 + 184, which is 376. If you want to estimate it, it would be $400.

Sabendo que senx=3/5 e que X € 1°quadrante, calcule tgx
guapka [62]
<span>se 
sen x = 3/5 eleva ao quadrado ambos os lados 
sen² x = (3/5)² 

Tem que partir da relação fundamental 

sen²x + cos²x = 1 
(3/5)² + cos² x = 1 

cos² x = 1 - (3/5)² = 16/25 

cos x = V(16/25 = 4/5 

b ) tg x = sen x / cos x = 3/5 / 4/5 = 3/5 * 5/4 = 3/4 

c) cotg x = cosx / sen x = 1 / tgx = 1/ (3/4 = 4/3 

d) sec x = 1/ cos x = 1 / 4/5 = 5/4 

e) cossec x = 1 / sen x = 1/ 3/5 = 5/3

How to solve -7+2x = -6x -71
Slav-nsk [51]

Answer:

x = -8

Step-by-step explanation:

to solve this kind of problem is very simple , just be very careful about the negative and positive signs.

-7+2x = -6x -71

we will collect the like terms or simply say that you will combine the like terms

we  have,

-7 + 2x + 6x = -71

2x + 6x = -71 + 7

8x = -64

divide both sides by 8

8x/8 = -64/8

x = -8
