How do i solve for x
-1/2x+1=-x+8

-1/2x + 1 = -x + 8

1/2x + 1 = 8

1/2x = 7

x = 14

Hope this helps! ;)

x=14

Step-by-step explanation:

Combine the like terms:

1-8= -x+1/2(x)

-7= -1/2x

-7/-0.5 =x

14 = x

Hope this helps!

what’s the question?

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
