A=$2588.570
Hence the answer is B. about $2,589

Please help me please please ASAP ASAP please ASAP
Answers
Answer:
45Step-by-step explanation:
Well, it is not 90 degrees, as it is not a right angle.
It cannot be 180 degrees as that would be a straight line and a triangle's whole angle measure is 180 degrees.
It is an acute angle, and appears to be half of 90 degrees, so I would have to say 45 degrees.
Not enough information is false because you can infer that it is 45 degrees by looking at it.
Hope that helps!
If 5x + 4y= 13 and 4x + 5y = 14, find the value of (x - y).
Answers
Answer:
x - y = - 1
Step-by-step explanation:
Given the 2 equations
5x + 4y = 13 → (1)
4x + 5y = 14 → (2)
Subtract (2) from (1) term by term , that is
(5x - 4x) + (4y - 5y) = 13 - 14
x - y = - 1
Answer:
x = 1
y = 2
x - y = -1
Step-by-step explanation:
5x + 4y= 13, then 4y = 13 - 5x, then y = (13 - 5x)/4
4x + 5y = 14
substitute for y:
4x + 5(13 - 5x)/4 = 14
simplifying:
4x + (65 - 25x)/4 = 14
4x + 16.25 -6.25x = 14
-2.25x = -2.25
x = 1
y = (13 - 5)/4 = 2

Answer:
Solution :
{x,y} = {0/14261512,4}
Step-by-step explanation:
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = x + 4
// Plug this in for variable y in equation [1]
[1] 12x - 5•(x +4) = -20
[1] 7x = 0
// Solve equation [1] for the variable x
[1] 7x = 0
[1] x = 0
// By now we know this much :
x = 0
y = x+4
// Use the x value to solve for y
y = (-0/14261512)+4 = 4
