<u>Given:
</u>
- The total weight of 6 pieces of butter and a bag of sugar is 3.8 Ib.
- The weight of the bag of sugar is 1.4 Ib
<u>Question:
</u>
What is the weight of each piece of butter?
<u>The Process:
</u>
The two steps for obtaining the weight of each piece of butter are as follows:
<u>Step-1:</u> the total amount of butter is the total bag of butter and sugar subtracted by the weight of the bag of sugar.
<u>Step-2:</u> the total amount of butter divided by the number of pieces of butter is the the weight of each piece of butter.
Let's also consider the following quick steps.
<u>Quick steps:
</u>
Therefore, the weight of each piece of butter is 0.4 lbs.

Answer:
Step-by-step explanation:
The sum of the angles in a triangle is 180 degrees. This means that in triangle ABC,
Angle A + angle B + angle C = 180
Therefore,
6x - 1 + 20 + x + 14 = 180
6x + x + 20 + 14 - 1 = 180
7x + 33 = 180
Subtracting 33 from the left hand side and the right hand side of the equation, it becomes
7x + 33 - 33 = 180 - 33
7x = 147
Dividing the left hand side and the right hand side of the equation by 7, it becomes
7x/7 = 147/7
x = 21
Therefore
Angle A = 6x - 1 = 6 × 21 - 1
Angle A = 125 degrees
Angle C = x + 14 = 21 + 14
Angle C = 35 degrees.
There will be a 25 grams left after 3240 years.
The half-life of Radium-226 is 1620 years. If we divide 3240 by 1620 the answer is 2. So that means the amount of Radium-226 will divide in half twice.
100 / 2 = 50 / 2 = 25
