Answer:

Integers include both positive and negative numbers, and there are several rules for adding integers. Adding two positive integers together will always result in a positive integer. For example, 6 + 4 = 10. To add two negative integers, add the numbers together and place a negative sign in front of the answer.

Find the value of x.<br><br> RZ = 30<br> SW = 5x - 20

Murrr4er [49]

|RZ|=0.5|SW| therefore 2|RZ|=|SW|.

5x - 20 = 2 · 30

5x - 20 = 60 |add 20 to both sides

5x = 80 |divide both sides by 5

x = 16

Solve the system of equations using elimination. SHOW WORK!!!!!!!!!!!!!

irinina [24]

q= 6

r= 7

work--

Multiply 1st column by -2:

-30q+8r=-124

5q+8r=86

Subtract 2nd column from the first column:

-35q= -210

Solve for q:

q=6

Subtract q=6 by any of the two equations, so:

-30q+8r=-124

-30*6+8r=-124

Solve for r:

r=7

It is 1/4*1/4=1/16. Since the probability of one number is 1/4, you need two numbers to become supplementary.

Fill in the blanks:

ser-zykov [4K]

Answer:

$8943=8\times 1000+9\times 100+4\times 10+3\times 1=8\times 10^3+9\times 10^2+4\times 10^1+3\times 1$

So in blanks there will be 8, 9, 4, 3

Step-by-step explanation:

We have given that $8943=.....\times 1000+....\times 100+....10+....1=....10^3+....10^2+....10^1+....1$

We have to fill the blanks

We know that $8\times 1000=8000$

$9\times 100$

$4\times 10$

$3\times 1$

When we add all then

$8000+900+40+3=8943$

So in the blanks there will be 8 , 9, 4 , 3

We also know that $8000=8\times 10^3$

$900=9\times 10^2$

$40=4\times 10^1$

$3\times 1=3$

So $8943=8\times 1000+9\times 100+4\times 10+3\times 1=8\times 10^3+9\times 10^2+4\times 10^1+3\times 1$
