Answer:
x=1.25
Step-by-step explanation:
Let us replace the number with the variable "x". You will then get this equation:
8x-2=8
Move the -2 to 8 and you would get the equation:
8x=8+2
Simplify:
8x=10
Simplify:
x=10/8
You would then get the answer "x=1.25"
I hope this helps :)

and we're done!
Answer:
f(4) = 22
Step-by-step explanation:
I think that you type wrongly.
we have f(1) = -5
and f(n) = f(n-1) + 9
Find f(4)
Then
with n= 2 we have f(2) = f(1) + 9 = - 5+ 9= 4
with n= 3 we have f(3) = f(2) + 9 = 4 + 9= 13
and finally with n= 4 we find f(4) = f(3) + 9 = 13+ 9= 22
So f(4) = 22
Hope you understand.
Answer:
x = 71
Step-by-step explanation:
The sum of the measures of the exterior angles of a polygon is always 360°.
A triangle has 3 exterior angles.
152+ 137+x = 360
Combine like terms
289 +x = 360
Subtract 289 from each side
289-289+x=360-289
x = 71
