Answer:
The answer is -13.
Step-by-step explanation:
=4×(-2)-5
=-8-5
=-13
The value of (-2) is -13.
x+142 =3x+64
subtract x from each side
142 = 2x+64
subtract 64 from each side
142-64 = 2x
78=2x
divide by 2
78/2 = x
x=39
The number is 39
0.95 in simplest form is 19/20
The yearly fee can be subtracted, resulting in 170-25.50=144.5
So with 10.50 a session, you must divide, resulting in around 13.8 sessions.
13 sessions if you need a whole number.
Hope this helps
