Arrange the following threading procedure of the sewing machine. Order of threading in the upper part 1. Pull the thread down to the thread guide
2. Locate spool pin and place your spool of thread
3. Thread the needle
4. Look for the thread guide and bring your thread into it.
5. Look for the thread take-up lever and raise it as it goes.
6. Locate the tension and pull the thread between the metal disc of the tension.​Arrange the following threading procedure of the sewing machine.

Threading the lower part of sewing machine.
1. Put the bobbin back to the bobbin case and pull the thread through the little slot at least 4 inches
2. Start the mechanism by rolling the balance wheel forward to get the thread of the bobbin through the needle.
3. Remove the bobbin from the case and wind the thread.
4. Pull the upper and lower thread together by 4 inches.
5. Remove the bobbin case by pulling on the bobbin case latch.​

the value of v.w= -12.

step-by-step explanation:

we are given three vector r,v and w as:

r = < 5, -5, -2> ; v = < 2, -8, -8> ; w = < -2, 6, -5>

we know that r,v and w could also be represented as:

r=5i-5j-2k

v=2i-8j-8k

and w= -2i+6j-5k

where i,j and k are the unit vectors of x,y and z-axis respectively.

also we know that it has the following property:

i.i=1 ; j.j=1; k.k=1

and i.=j.i=i.k=k.i=j.k=k.j=0

i.e. when we multiply two vectors or we find it's dot product we need to only multiply the components of x coordinates with each other; y with each other and z with each other.

hence, v.w= (2i-8j- -2i+6j-5k)

                  = 2×(-2)+(-8)×(6)+(-8)×(-5)

                  = -4-48+40

                  = -12

hence, v.w= -12

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

answer: 5100 just subtract
