Answer:

(-1/2,2)

Step-by-step explanation:

2(4x+y=0)=8x+2y=0

8x+2y=0

-(8x-y=6)

3y=6

Divide both sides y=2

4x+2=0

4x=-2

Stefan sells Jin a bicycle for ​$176 and a helmet for ​$16. The total cost for Jin is ​160% of what Stefan spent originally to b
Elis [28]

Answer:

Stefan originally paid $120 for the bicycle and helmet.

He made $72 by selling them to Jin.

Step-by-step explanation:

Given that:

Selling price of bicycle = $176

Selling price of helmet = $16

Total price = 176+16 = $192

This is 160% of what Stefan paid originally.

Let,

x be the original amount paid by Stefan.

160% of x = 192

\frac{160}{100}x=192\\1.6x=192

Dividing both sides by 1.6

\frac{1.6x}{1.6}=\frac{192}{1.6}\\x=120

Original amount paid by Stefan = $120

Profit = 192 - 120 = $72

Hence

Stefan originally paid $120 for the bicycle and helmet.

He made $72 by selling them to Jin.

Find the sum of: 72 − 104 + 5 and -32 + 4 - 10. What should be added to 32 + 32 + 3 to get 3 + 3 ? (1 mark) 3. Subtract the sum
Rzqust [24]

Answer:

a). -65

b). -61

c). -20ab + 3bc +3ac

Step-by-step explanation:

According To the Question,

a). the sum of 72 − 104 + 5 and -32 + 4 - 10 .

  • (72 − 104 + 5) + (-32 + 4 - 10)
  • (-27) + (-38)
  • -27 - 38
  • -65

b). What should be added to 32 + 32 + 3 to get 3 + 3 , Let X be Added .

  • Thus,  (32 + 32 + 3) + X = 3 + 3
  • 67 + X = 6
  • X = 6 - 67
  • X = -61

c). Subtract  the sum of 12ab –10bc –18ac and 9ab + 12bc + 14ac from the sum of ab + 2bc and 3bc – ac.

  • Thus, [(ab + 2bc) + (3bc – ac)] - [( 12ab –10bc –18ac) + (9ab + 12bc + 14ac)]
  • (ab + 5bc - ac) - (21ab + 2bc - 4ac)
  • ab + 5bc - ac - 21ab - 2bc + 4ac
  • -20ab + 3bc + 3ac
