The best option here is option B) -14
Isolate the w. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS. First, multiply 4/3 to both sides
(3/4)(4/3)(8w - 12) = 3(4/3)
8w - 12 = (12/3)
8w - 12 = 4
Isolate the w. Add 12 to both sides
8w -12 (+12) = 4 (+12)
8w = 4 + 12
8w = 16
Finally, to completely isolate the w, divide 8 from both sides
8w/8 = 16/8
w = 16/8
w = 2
2 is your answer for w

Answer:
6
Step-by-step explanation:
Answer:
3x+15= 4x-10
3x-4x= -10-15
-x= -25(minus will be cut on both sides)
so x= 25
x = 51.98
Step-by-step explanation:
tan 68 = opp/hyp = x/21
or
x = 21×tan68°
= 21(2.475)
= 51.98
