T= 7/18 in fraction form
in expanded form its 144- 216t= 60
Alternate forms are 84 - 216t = 0 and -72 ( 3t - 2 = 60)
The result is 72 ( 2 - 3t) = 60

Answer:
Circular shapes - They are those planner shapes that represent the locus of all the points that has a constant distance from a fixed point on the plane. This constant distance is termed as the radius of the circle and the fixed point is known as the center of the circle.
The center of the circle is enclosed by all the points on its periphery.
The circumference of the circle is the total length of its periphery around the center.
Concentric circles are two circles that have the same center
Step-by-step explanation:
Answer:
x= 18
y =45
Step-by-step explanation:
first these two angles are supplementary and add up to 180 degrees:
(6x+7) + (4x-7) = 180
find x:
10x = 180
x = 18
substitute x = 18 for the angle (6x+7)
now we know what 6x +7 =
6 (18) + 7 = 115
since angle 3y-20 = 115, solve for y
3y = 135
y = 45
-5
a^2-25=0
a^2=25
take the square root of both sides
a=5, and -5
