Well to find this answer, we will have to find a common denominator for each fraction so it will be easier to subtract.
9 is a common denominator for both numbers since both denominators, 9 and 3, can go into 9. We don't have to change 2/9, but we will have to change 1/3.
Multiply 1 and 3 by 3 to get our new fraction 3/9.
2/9-3/9= -1/9
So our answer would be - 1/9. Hope I helped!

If XY=18, YZ=14, and XZ=20, find the radius of each circle.

Pachacha [2.7K]

Let`s assume that points M, N and P are the touching points of those 3 circles:Then:Y M + M Z = 14,Z N + N X = 20X P + P Y = 18And also: M Z = ZN, Y M = P Y and N X = X P.Now we have a system of 3 equations ( Y M, M Z and X P are the radii of each circle ):Y M + M Z = 14M Z + X P = 20X P + Y M = 18 Y M - M Z = - 14+X P + Y M = 18 X P - M Z = 4Y M - M Z = - 14+M Z + X P = 20 X P - Y M = 6 /* ( - 1 )X P - M Z = 4 X P + Y M = - 6 X P - M Z = 4 Y M - M Z = - 2 Y M + M Z = 14 2 Y M = 12 => Y M = 6M Z - 6 = 2 => M Z = 8X P + 6 = 18
X P = 12
Radii of the circles are: 12, 8 and 6.

Solve -5 + w divided by 3 = -1. 12 -12 2 -2

Hello!

Answer:

w=12

*The answer must have a positive sign.*

Step-by-step explanation:

First, you add by 5 from both sides of an equation.

$-5+\frac{w}{3}+5=-1+5$
