3/4=21/28
2/7=8/28
so
21/28-8/28=13/28
answer =13/28
So first u need to get the variables separate from the constants so add 8 to both sides. then u get 4x = 4 then u can divide each side by 4 to get x alone.
so the answer is
x = 1
Answer:
4.4
Step-by-step explanation:
Data set = 79, 93, 92, 86, 90
Xmean = (79 + 93 + 92 + 86 + 90)/5
= 440/5
Xmean = 88
MAD =
(79 - 88) + (93 - 88) + ( 92 - 88) + ( 86 - 88) + ( 90 - 88)/ 5
=
(9) + (5) + (4) + (2) + (2)/ 5
=
22/5
Mean Absolute Deviation = 4.4
Answer:
Yes
Step-by-step explanation:
Plug in the coordinate (5,9) into the equation
9=3(5)-6
9=15-6
9=9
Point form: (1,-1)
equation form: x = 1, y = -1
