For this case we have the following property of the sum:
What we need to know is that the name of this property is:
Identity property of the sum.
What this property establishes is:
Every number added to zero is equal to the same number.
Answer:
the number sentence show:
Identity property of the sum.
Answer:
15 grams
Step-by-step explanation:
If the copper made up 80% of the weight of the bar (w), then the bar weighed ...
0.80w = 12 g
w = (12 g)/0.80 = 15 g
_____
Copper has a density of about 8.96 g/cm³, so Nancy's "large" metal bar is about the size of two sugar cubes.

Answer:
16.1 Inches
Step-by-step explanation:
In ΔKLM,
∠K+∠L+∠M=180°
∠K+161°+18°=180°
∠K+179°=180°
∠K=180°-179°=1°
To determine k in the diagram, we use the Law of Sines.
k X Sin 161°=300 X sin 1°
k=(300 X sin 1°)÷sin 161°
k=16.1 inches (correct to the nearest tenth of an inch)
