Answer Z = -1/4

Step-by-step explanation:

-1/3+2z= -5/6

Add 1/3 to both sides

-1/3+2z+1/3 = -5/6+1/3

Simplify

2z=-1/2

Divide both sides by 2

2z/2 = -1/2/2

Simplify

z = -1/4

an=4n+1

Sum of first 30 terms

a1+a2+.................a30

Sn=(a1+an)*n/2

a1-----------first terms

an=---------last term-----a30

n= number of terms-----30

calculation of a1

a1=4n+1=4*1+1=5

calculation of an

a30=4*30+1=121

S30=(a1+a30)*30/2

S30=(5+121)*30/2=1890

<span>The sum of first 30 terms is 1890</span>

Help me with this question ;<;

Let's set this up in equation form!

We know that 15 equals b and 8 together.

15 = b + 8

b = 7

The value of b that makes the equation true is 7.

Hope this helps!! :)

Answer:

( -8,0, 0) , ( -8, 1, 0) and ( -8, 1, -5)

Step-by-step explanation:

We need to visualize the given situation in 3D

Coordinates is in the form of (x, y, z)

Henna starts from origin moves back 8 units Negative x-axis

x = -8 point will be ( -8,0, 0)

turning 1 unit right will be parallel to the y axis in positive y-axis direction

y = 1 point will be ( -8, 1, 0)

Moving down by 5 units, Negative z-axis

Z = -5 point will be ( -8, 1, -5)
