4x - 5y = 3
x = 3 - 1/2y
4(3 - 1/2y) - 5y = 3
12 - 2y - 5y = 3
12 - 7y = 3
7y = 12 - 3
7y = 9
y = 9/7
x = 3 - 1/2y
x = 3 - 1/2*9/7
x = 3 - 9/14
x = 42/14 - 9/14
x = 33/14
The correct answer is C. 33/14.
Answer:
rad66/11
Step-by-step explanation:
Using Sohcahtoa, you can find that the tangent is the opposite side over the adjacent side. This means that the tangent of angle X is 2rad6/2rad11. You then simplify it to rad6/rad11. Preferably, a radical shouldn't be in the denominator. You can muliply both sides by rad 11 to balance the equation into rad66/11.
CHECK THE ATTACHMENT FOR THE FIGURE OF THE QUESTIONS
Answer:
Option A. is correct x = 4
Step-by-step explanation:
From the given figure
The adjacent of the given right angle triangle is
8 units which is the base,
Then x units is the opposite of the right angle triangle which is the height.
The hypotenuse side also has x units
Then value of x is required,
But going by right angle triangle trigonometry
cos(x) = adjacent / hypotenuse
Where adjacent= 8 unit
cos( 60) = 8/x
1/2 = 8/x
x = 8/2
= 4unit
Hence, Option A is correct, with 4 units
It would be n=-6 because you would first distribute it out then solve order of operations as you go
