Answer: -8.8n + 7.8
Step-by-step explanation:
2.8 - 5.8n - 3n + 5
Add -5.8n and -3n to get -8.8n
Add 2.8 and 5 together to get 7.8
You simply need to subtract x from both sides:
In fact solving an equation for a variable means to isolate that variable on one side of the equation, and moving all remaining terms on the other side.
In this case, we solved the equation for y, because we wrote it as 
Answer:
AC = 40
Step-by-step explanation:
A quadrilateral is a polygon shape with four sides and four angles. The interior angle of a quadrilateral sums up to 360°.
A parallelogram is a quadrilateral (has four sides and four angles) in which has two pair of opposite sides are parallel to each other. The diagonals of a parallelogram bisect each other.
Given parallelogram ABCD:
Diagonals AC and BD bisect each other at point E. Hence:
AC = AE + CE (line segment addition postulate)
Also:
AE = CE (diagonal BD bisects AC at point E).
Hence; x + 16 = 5x
5x - x = 16
4x = 16
x = 4
AE = x + 16 = 4 + 16 = 20; CE= 5x = 5(4) = 20
AC = AE + CE = 20+ 20 = 40
