Answer:
W=9
Step-by-step explanation:
45=9(w-4)
45=9w-36
+36. +36
81=9w
81÷9=9w÷9
9=w
The only one i know is number 6 which the answer is 36
Answer:
17
Step-by-step explanation:
The diagonals in a parallelogram bisect each other, creating two equal halves. So HV = 1/2 of XV
HV = XV/2
HV = 34/2
HV =17
It is possible because you can have 2 acute angles in the triangle and on right angle making it a acute right triangle.

Answer:
(x, y, z) = (1/3, 2/3, 1)
Step-by-step explanation:
We can use the first equation to write an expression for x that can be substituted into the other equations.
x = 1 -y
2(1 -y) -y +z = 1 ⇒ -3y +z = -1
(1 -y) +2y +z = 8/3 ⇒ y +z = 5/3
Subtracting the first of these equations from the second gives ...
(y +z) -(-3y +z) = (5/3) -(-1)
4y = 8/3
y = 2/3
z = 5/3 -y = 1
x = 1 -y = 1/3
The solution is (x, y, z) = (1/3, 2/3, 1).
