Answer:
<em>B. 74.89</em>
Step-by-step explanation:
sin(27) = 34/x
sin(27) → 0.45399049974 ≈ 0.45399
x = 34/0.45399
x = 74.89
Hope this helped! :)
C= o because the c=5x-4y the x is 0 and the y is 0 so your answer is zero
A) 2x - 7 = -1
Add 7 to both sides of the equation.
2x = 6
x = 3
Choice A is not the answer.
B) 3x + 8 = 1
Subtract 8 from both sides.
3x = -7
Divide both sides by 3.
x = -2.3 repeating
Choice B is not the answer.
C) 1/2x + 8 = 10
1/2x = 2
Divide both sides by 1/2.
x = 4
Choice C is not the answer.
By process of elimination, choice D is the answer.
D) 1/2(2x - 6) = -6
x - 3 = -6
Add 3 to both sides.
x = -3
You multiply 33 by 0.9 because it's minus 10% (0.1) and the answer is $29.7
Step-by-step explanation:
Using Pythagoras theoram,
AC²= AB²+BC²
