X=0 bexause the 3s cancel out and your left with 2x=0 so x=0
Answer: 0.99
Step-by-step explanation: sin 90 Divided by 85 = sin x divided by 13
sin x =13x sin 90 divided by 85
sin x = 13divided by 85
sin x = .152941176
arc sine of .152941176= 8.79741071 degrees
cos 8.79741071 = .988235294
.99
Line a can be rewritten as
.. 2y -x = 12
The coefficients of y and x match those of line b, so lines "a" and "b" are parallel.

Answer: 17</h3>
Multiply the probability of getting a correct answer (0.25) with the number of questions (68) to get 0.25*68 = 17
The student should expect to get about 17 questions correct.
Multiply 2*(-75) = -150
Since you need the absolute value... turn it positive
The answer is 150
