Answer:
<em>- 8/3 </em>
Step-by-step explanation:
because you have to multiply 4 x 2/3 then subtract that by 8 and that will give you the answer and i got it right so i swear.
For number 5 - .3 ( 3.60 ÷ 12 = .3)
For number 6 - .32 ( 2.56 ÷ 8 = .32)
For number 7 - 2 ( 2.36 ÷ 2 = 1.18)
Using the two coordinates you can find the equation
------------------------------------
Find slope first
Slope

0 - 3 = -3
-------
-4 - 0 = -4
--------------------------------------------------
Simplify -3/-4
3/4
-----------------------------------------------------------
Your slope is 3/4 and the Y-intercept as mentioned in the question is "3"
----------------------------------------------------------------------
So your equation is y = 3/4x + 3
If you are saying 72 / 8 then its 9 it's only reversed multiplication
Answer:
16. 142 deg
17. 23 deg
18. 134 deg
19. 38 deg
Step-by-step explanation:
16.
m(arc)QT = 2m<QST = 2 * 71 = 142
17.
m<STR = (1/2)m(arc)RS = (1/2)46 = 23
18.
RT is a diameter since it includes the center of the circle, point X.
m(arc)RST = 180
m(arc)RS + m(arc)ST = m(arc)RST
46 + m(arc)ST = 180
m(arc)ST = 134
19.
RT is a diameter since it includes the center of the circle, point X.
m(arc)RQT = 180
m(arc)RQ + m(arc)QT = m(arc)RQT
m(arc)RQ + 142 = 180
m(arc)RQ = 38
