You need to put dominators as same number

so 5 can be 15

-1/15 -( -3/5)
-1/15- (-3x3/5x3)
-1/15 -(-9/15)
-1 +9 =8
             /
              15
=8/15

Mars has m moons. The number of moons of Pluto is one more than twice the number of moons of Mars. The number of moons of Neptun
tigry1 [53]

Answer:

Neptune has 2 more than 6 times the number of moons on mars

Explanation:

neptune = 6m+2

mars has 'm' moons

pluto has one more than twice that of mars, = 2m+1

neptune is one less than thrice of pluto

= 3(2m+1) -1

= 6m+3 -1

= 6m+2

B(n)=1 (-2)^n-1<br> What is the 4th term in the sequence
Vera_Pavlovna [14]

Answer:

The 4th term in the sequence is -8.

Step-by-step explanation:

The nth term of the sequence B is given by:

B(n) = (-2)^{n-1}

So the fourth term will be given by:

B when n = 4, that is, B(4).

B(4) = (-2)^{4-1} = (-2)^{3} = -8

The 4th term in the sequence is -8.

Show me how to get this answer show your work
Rama09 [41]

We know that angle MKJ is comprised of angle MKL and angle LKJ. That means if we add MKL and LKJ, we should get 80 degrees, which is the measure of angle MKJ.

MKL + LKJ= MKJ \implies \\ 2x+10+3x-5=80 \implies \\ 5x+5=80 \implies\\ 5x=75 \implies \\ x=15

So, we know that our x is 15. That is not enough to tell whether KL is an angle bisector, because we have to evaluate both MKL and LKJ with x=15, so:

MKL=2(15)+10 = 40\\ LKJ=3*15-5=40

So we see that these two angles are actually bisectors, and the third question best describes this phenomenon.
