-24x -15 = -27. Step by step explanation on how to solve this problem.

x =

Step-by-step explanation:

Given

- 24x - 15 = - 27 ( add 15 to both sides )

- 24x = - 12 ( divide both sides by - 24 )

x = =

1/2 or 0.5

Step-by-step explanation:

   -24x - 15    = -27

-24x - 15 + 15 = -27 + 15

       -24x       = -12

          x          = 1/2 or 0.5

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

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
