Answer:
a = 0
Step-by-step explanation:
a + 5 = -5a + 5 subtract 5 from both sides
a + 5 - 5 = -5a + 5 - 5
a = -5a add 5a to both sides
a + 5a = -5a + 5a
6a = 0 divide both sides by 6
6a / 6 = 0 / 6
therefore,
a = 0
Answer:
c=3
Step-by-step explanation:
First simplify like terms.
1+4c=7+2c
1+2c=7 (subtract 2c from both sides)
2c=6 (subtract 1 from both sides)
c=3 (divide by 2)
CHECK:
1+4(3)=7+2(3)
1+12=7+6
13=13
Yes!

Answer:
5.4'
Step-by-step explanation:
See diagram attached.
The 8' wire is the hypotenuse of the triangle, with a base angle of 42°.
Hence the height is the length of the hypotenuse multiplied by sin(42°)
H = 8sin(42°) = 8 *0.6691 = 5.353'
