Each lemonade costs about $2.22. You can achieve this answer by dividing 12 by 5.40.
The answer is D I think
Given the 2 equations
2x + 5y = 21 → (1)
x + y = 3 → (2)
Rearrange (2) expressing y in terms of x, by subtracting x from both sides
y = 3 - x ← Substitute into (1)
2x + 5(3 - x) = 21 ← distribute and simplify left side
2x + 15 - 5x = 21
- 3x + 15 = 21 ( subtract 15 from both sides )
- 3x = 6 ( divide both sides by - 3 x = - 2 → D
X=-2
AC # A'B'
Step-by-step explanation:
While solving the above problem one must keep in mind that
- Reflection along Y-axis would just make the rectangle upside down at the same distance from X-axis in the down direction.
Thus, from the figure it becomes clear that
- AB ∦ B’D’
- CD║A’B’
- BD ∦ C’D’
Only statement that comes out true is the third statement which states that AC is not parallel to A’B’
Since the diagonal of a rectangle can not be parallel to one of its side (though the side in question is side of the same rectangle reflected in y axis)
