Sin (x + y) = sin x cos y + sin y cos x
Answer:
the answer is 5.8
Step-by-step explanation:
divide numerator (8) by the denominator (10):
8 / 10 = 0.8
add this value to the integer part: 5 + 0.8 =
5.8 So,
5 8/10 = 5.8
Answer:
x=2
Step-by-step explanation:
Convert the Y to 3x since we know that y=3x.
You would get x+3x=8.
Add the x and 3x to get 4x
Then, you would get 4x=8.
Divide by 4 on both sides to get x=2.
Answer: 99
Step-by-step explanation:
55/100 = 0.55
0.55 * 180 = 99
Answer:
(2,-2)
Step-by-step explanation:
To solve this using substitution you would take your second equation and plug it in for y of the first equation (4x-10= -3x+4). You then would add the 10 over (4x= -3+14). Next you add the 3x over(7x=14). Finally divide both sides by 7, which should give you x=2. Now all you have to do is plug the two in for x in one of your equations (which ever equation you prefer) (y=-3(2)+4). Solve the equation and you will then have the answer to y, which you can then put into a point.
