27 millimeters multiplied by 1 cm/10 mm= 2.7 centimeters
Answer:
3
Step-by-step explanation:
tan 60 = root(3)
tan² 60 = {root (3)}²
tan² 60 = 3
322/14 = 23
322 / 14
14 cannot go into 3, so 14 can go into 32 twice,
32-28 = 4 drop the 2
42. 14 can go into 42 3 times
42-42 = 0
Your answer is 23
You need to get y alone for both equations. for x-y=7, you subract x from both sides. (giving you -y = 7 - x) then, multiply the whole equation by -1 to make the y positive, which gives you y = x - 7.
here is the system in y intercept form so you can graph it easier:
*y = x - 7
*y = x + 4
Answer:
-3
Step-by-step explanation:
You would find what the answer to (5•3) is then subtract that answer with 18. So it would be 15-18=-3
