Answer:
Gold
Step-by-step explanation:
<em>Casandra finds a treasure chest packed with metallic coins. The chest has a volume of 0.25 cubic meters. The coins have a combined mass of 4825 kg. Hoping to find gold, she calculates the density to determine the metal of the coins.</em>
<em>What kind of metal are the coins made of?</em>
<em>Bronze (8700 kg per cubic meter)</em>
<em>Silver (10500 kg per cubic meter)</em>
<em>Lead (11300 kg per cubic meter)</em>
<em>Gold (19300 kg per cubic meter)</em>
<em />
Density is mass per volume:
D = M / V
D = (4825 kg) / (0.25 m³)
D = 19,300 kg/m³
The coins must be made of gold.
Answer:
3
Step-by-step explanation:
6x+2y=12
2y=6x-12
y=6x/2- 12/2
y=3x-6
Answer:
<u>(x² + 4x + 6)/ 3x + 12</u>
<u>This is the most simplified form</u>
Step-by-step explanation:
Let's simplify the expression:
(x + 6)/(x + 4) + (x - 3)/3
Least Common Denominator : 3 * (x + 4)
[3 * (x + 6) + (x - 3) (x + 4)]/ 3 * (x + 4)
Solving parentheses:
[3x + 18 + x² - 3x + 4x - 12]/ 3 * (x + 4)
Like terms:
<u>(x² + 4x + 6)/ 3x + 12</u>
<u>This is the most simplified form</u>
