Answer:

x=11

Step-by-step explanation:

You do 38/3x+3 and 19/x+7 and then cross mulitply and get 57x+57=38x+266. Then yoy subtract 57 from 266 and get 57x=38x+209. Now you have to subtract 38 from 57 and then answer will be 19. So now you have 19x=209. Finally you divide 209 by 19 and get x=11. Good luck!

NemiM [27]

Answer:

f(-4) = -12

Step-by-step explanation:

f(x)=2x-4

To calculate f(-4), we need to substitute x in our equation above with -4:

f(x)=2x-4\\f(-4) = 2*(-4) - 4\\f(-4) = -8-4 = -12

Note that 2*(-4) = -8

Answer: f(-4) = -12

a suit is being sold at a 20 % off (discount). The sale price is $ 270. What was the original price ?
Lisa [10]

Answer:

The original price is 337.50

Step-by-step explanation:

If we get 20% off, we still have to pay 100-20 =80%

Let x be the original price

x *80% = 270

.80x = 270

Divide each side by .80

.80x/.80 = 270/.80

x =337.50

The original price is 337.50
