36. P=1/2Q-15
37. R=IV
38. b=-mx+y
39. a) t=-d-e+f
b) t=19.175
40. No, X=-2.4
Step-by-step explanation:
Explanation for 40:
2(x-4)-4x=-6x+9x+4
first do the parentheses
2x-8-4x=-6x+9x+4
next combine like terms
-2x-8=3x+4
add 2x to each side
-8=5x+4
subtract 4 from each side
-12=5x
divide both sides by 5
x=-2.4
