Answer: she mailed 3 letters to Europe
Step-by-step explanation:
Let x represent the number of letters that Nancy mailed to Europe.
Let y represent the number of letters that Nancy mailed to United States.
Nancy mailed 5 letters, some to Europe and some to the United States. This means that
x + y = 5
A letter mailed within the United States costs $0.44. A letter to Europe from United date cost $ 0.94 to mail. If the letters that Nancy mailed cost $3.70, then
0.94x + 0.44y = 3.7 - - - - - - - - - - - -1
Substituting x = 5 - y into equation 1, it becomes
0.94(5 - y) + 0.44y = 3.7
4.7 - 0.94y + 0.44y = 3.7
- 0.94y + 0.44y = 3.7 - 4.7
- 0.5y = - 1
y = - 1/ - 0.5 = 2
x = 5 - y = 5 - 2
x = 3
B. A square is a rhombus.
C. A rhombus is a square.
D. A rectangle is a square.
The correct statement that is always true from the given options is:
B. A square is a rhombus.
A square is a special type of rhombus where all four sides are equal in length and all angles are right angles.
A rhombus, on the other hand, is a quadrilateral with all sides of equal length.
Therefore, every square can be classified as a rhombus, but not every rhombus is a square.
Hence the correct statement that is always true from the given options is:
B. A square is a rhombus.
