7/6x=140
since variable x is multiplied by 7/6, find x by multiplying by the inverse of 7/6 which is 6/7.
7/6x × 6/7 = 140 × 6/7
x= 120
Coordinates of the center: ( 4, 4 )
The radius: r = 7 - 4 = 3
The equation of a circle:
( x - 4 )² + ( y - 4 )² = 3²
x² - 8 x + 16 + y² - 8 y + 16 = 9
x² + y² - 8 x - 8 y + 32 - 9 = 0
Answer:
A ) x² + y² - 8 x - 8 y + 23 = 0
(2/6) × 24 = m
(1/3) × 24 × 3(to take out (1/3)) = m × 3
24 = m×3
24÷3 = m×3 ÷3
8 = m
m = 8
So the answer should be B. 8
Hope I can help :)

=
use the cross method solve the equation.
9P+90=8P-56
9P-8P=-56-90
P=-146
Hope this helps.
26+35+10+18+15+37+25+20+15/9= 22.33
