Hmm ok what thw answer would be is x=-0.4
Since you subtract 0.4 from both sides end up with -9x=3.6 and then divide -9 on both sides -9x/-9 cancel and 3.6/-9 and end up with x=0.4 hope this helped
Answer: You must try to learn by yourself. ;)
Step-by-step explanation: Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division.

Answer:
The length of the wire is 76.19 m.
Step-by-step explanation:
It is given that a guy wire is attached to the top of a radio antenna and to a point on horizontal ground that 40 m from the base of the antenna.
It means base of the right angled triangle is 40 m.
The wire makes an angle of 58deg 20min with the ground.
1 degree = 60 min
Using this conversion convert the given angle in degree.
In a right angled triangle
Therefore the length of the wire is 76.19 m.
