Subtract 14 from both sides
5=15x
\frac{5}{15} =x
x= \frac{1}{3}

When 5√20 is written in simplest radical form , the result is k√5 what is the value of K
Vladimir [108]

Answer:

Step-by-step explanation:

√20 can be rewritten as the product of two radicals:  √4√5,

and √4 = 2.

Thus, 5√20 = 5(2)√5 = 10√5.  Thus, B:  10 is correct; k = 10.

For a two column proof, we want to start with the given information. From there, we will use various definitions, postulates, and theorems to fill in the rest.

Our two sets of given information are that Plane <em>M </em>bisects Line <em>AB </em>and that Line <em>PA</em> is congruent to Line <em>PB</em>.

We know from the definition of a bisector that it splits a line in two equal parts. Therefore, Line <em>AO</em> must be congruent to Line <em>BO</em>.

Now, we have two sides of a triangle that we have proved to be congruent to each other. From the image given in the original problem, we see that both triangles share Line <em>OP. </em>Line <em>OP</em> is congruent to Line <em>OP</em> through the reflexive property.

We now have proven that all three sides of the one triangle are congruent to the corresponding sides on the other triangle. Therefore, the triangles are congruent through the SSS theorem.

-2x + 3y = 18. x = -y + 1
Bezzdna [24]

Answer:

D. X=-3, y=4

Step-by-step explanation:

-2x+3y=18 equation 1

x=-y+1 equation 2

-2(-y+1)+3y=18 replace x value of equation 2 into equation 1

2y-2+3y=18

5y=20

y=4

solve for x by replacing y value into either equation.

x=-y+1

x=-4+1

x=-3
