Answer:
<u>There were 12 gold coins in the chest at the start.</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
x = Number of gold coins in a chest
1/2x = Number of gold coins taken by the captain
1/4x = Number of gold coins taken by Sally
3 = Number of gold coins left
2. How many coins were in the chest at the start?
Let's write the following equation to solve for x:
1/2x + 1/4x + 3 = x
2x + x + 12 = 4x (Lowest Common Denominator is 4)
4x - 2x - x = 12 (Like terms)
x = 12
<u>There were 12 gold coins in the chest at the start.</u>
Number three is a parallelogram
Number four is a rhombus
The attributes of each quadrilateral is that it must have four sides
Number seven is true because if you fold a rectangle in half it will be congruent and rectangles always have at least one parallel side
Number eight is false because a square has all equal length sides and a rectangle does not have all equal sides making the two very different
