900x300=270,000 plus 2 would equal 270,002.4 devided by 3-2001 would equal 87,999.8
Answer:
Step-by-step explanation:
<u>Jane's caldles:</u>
- Cost = $20, Price = $3 per candle
<u>Chris's candles:</u>
- Cost = $40, Price = $5 per candle
<u>Profit, if equal per x candles is:</u>
- 3x - 20 = 5x - 40
- 5x - 3x = 40 - 20
- 2x = 20
- x = 10
Each will have profit of $10 if 10 candles sell
So you have 6x-20 and 4x+30. These angles are perpendicular to each other, meaning together they equal 180 degrees. To solve for this equation add both of the equations together equal to 180.
6x-20+4x+30=180
Now subtract: 30-20= 10 so 180-10= 170
Next add 6x to 4x= 10x
So 170=10x
X=17
Now we use substitution to simplify our answers into numerical form:
6(17)-20= 82 this is for 6x-20
4(17)+30= 98 this is for 4x+30
Hope that helps! :)
2.7 gallons.
Since the tank is already 4/5 full, only 1/5 is needed to fill it completely. As 13.5 gallons represent 5/5 (the full tank), you can take 13.5 divided by 5 to find 1/5.
