Answer:

x=-3

Step-by-step explanation:

Move the 9 to the other side of the equal Sign making it negative

Then also move the -30 to the other side to isolate the term 9x

-3 + 30 = 27

Divide both sides (which should now have -9x = 27) by -9x to isolate the variable

27/-9x = -3

Answer:

\Huge\boxed{\mathsf{\Rightarrow X=-3}}}

Step-by-step explanation:

Isolate x on one side of the equation.

First, switch sides.

9x-3=-30

Next, add 3 from both sides.

9x-3+3=-30+3

Solve.

-30+3=-27

9x=-27

Then, divide by 9 from both sides.

9x/9=-27/9

Solve.

Divide the numbers from left to right.

-27/9=-3

X=-3

In conclusion, the final answer is x=-3.

Fill in the blanks to rewrite the following statement with variables: Given any positive real number, there is a positive real n
sveticcg [70]

Answer:

a) there is s such that <u>r>s</u> and s is <u>positive</u>

b) For any <u>r>0</u> , <u>there exists s>0</u> such that s<r

Step-by-step explanation:

a) We are given a positive real number r. We need to wite that there is a positive real number that is smaller. Call that number s. Then r>s (this is equivalent to s<r, s is smaller than r) and s is positive (or s>0 if you prefer). We fill in the blanks using the bold words.

b) The last part claims that s<r, that is, s is smaller than r. We know that this must happen for all posirive real numbers r, that is, for any r>0, there is some positive s such that s<r. In other words, there exists s>0 such that s<r.

The length of a rectangle is 11 less than 9 times the width. The
Olin [163]

Answer:

Length = 7   Width = 2

Step-by-step explanation:

L = Length

W = Width

L=9w-11

2L+2W=18

2(9W-11) + 2W = 18

18W - 22 +2W = 18

20W -22 = 18

20W = 40

W = 2

L = 9(2)-11

L=18-11

L=7
