Solve this inequality for x 81 -1 1/5r <55

allsm [11]

$81-1\dfrac{1}{5}r < 55\qquad|\text{subtract 81 from both sides}\\\\-\dfrac{1\cdot5+1}{5}r < -26\qquad|\text{change the signs}\\\\\dfrac{6}{5}r > 26\qquad|\text{multiply both sides by 5}\\\\6r > 130\qquad|\text{divide both sides by 6}\\\\r > \dfrac{130}{6}\\\\r > \dfrac{65}{3}\to r > 21\dfrac{2}{3}$

given that the center of a circle is at point (-3,5) and that the radius of the circle is 6 units, write the the equation of the

Anika [276]

The equation of a cricle is
$(x-h)^{2}+(y-k)^{2}=r^{2}$
h being the x coordinate of the given point and k being the y coordinate of the given point (r also being the radius).

Now we have to plug the points into the equation
$(x--3)^{2} +(y-5)^{2} = 6^{2}$
now just simplify the the equation
$(x+3)^{2} +(y-5)^{2} = 36$

3x+5=245 Helpppppppppppp

SOVA2 [1]

Answer:

X = 80

Step-by-step explanation:

Subtract "5" from both sides,

3x + 5 - 5 = 245 - 5

Simplify,

3x = 240

Divide both sides by "3",

3x/3 = 240/3

X = 80

Hope this helps :-)
