Since we know that the perimeters are equal, we can make an equation where the sum of the side lengths of one triangle equal the sum of the side lengths of the other triangle. This yields (x-2)+(x)+(3x+1)=(2x-5)+(x+4)+(6x-7). If we combine like turns, the equation becomes 5x-1=9x-8. We can use the subtraction property of equality to isolate the x and the integers by saying 9x-5x=-1-(-8). Simplifying this gives 4x=7 or x=1.75
Hope this helps.

The equation that represent this situation is
convert to mixed number
The first thing to do in this case is to find the volume of the sphere.
We have then:
V = (4/3) * (pi) * (r ^ 3)
V = (4/3) * (pi) * ((4) ^ 3)
v = 268 in ^ 3
Then, the but of the sphere will be given by:
W = (0.075) * (268)
W = 20
Answer:
the weight of the sphere, to the nearest pound is:
A) 20
(2x+5)=Inscribed Angle
50 = Arc Length
Inscribed Angle=1/2Arc Length
2x+5=1/2(50)
2x+5=25
2x=20
X=10
71/20 is not in simplest form because you need to change it into a mixed number by dividing 71 and 20 and putting the remainder over 20.
