<h3>Given :- </h3>

\quad \qquad \bullet \quad \sf x = 3

<h3>To Find :- </h3>

\quad \leadsto \quad \sf \dfrac{3x - 5 ( 9 \times 3 )}{2}

<h3>Solution :- </h3>

Let's Start :-

\quad \leadsto \quad \sf \dfrac{3x - 5 ( 9 \times 3 )}{2}

Putting the respective value of x we have ;

{ : \implies \quad \sf \dfrac{3\cdot 3- 5 (27 )}{2}}

{ : \implies \quad \sf \dfrac{9- 135}{2}}

{ : \implies \quad \sf - \dfrac{126}{2}}

{ : \implies \quad \bf - 61}

\quad \qquad { \bigstar { \underline { \boxed { \pmb { \bf { \red { \underbrace { \therefore \dfrac{3x - 5 ( 9 \times 3 )}{2} = - 61}}}}}}}}{\bigstar}

The coordinates of an ordered pair have opposite signs. In which quadrant(s) must the ordered pair lie? Explain.
Alex_Xolod [135]
Alright...so the coordinates of an ordered pair have opposite signs [one sign is positive while the other is negative] so we could have an example of (-x,+y) or (+x,-y) ...that means out of the 4 quadrants these points could be in the 2nd quadrant or the 4th quadrant or corners of the graph

ANSERR GIVE ME ANSWERS PLS
Zarrin [17]

Answer:

Concept: Mathematics

When you multiply a number by something to the 10 power of something then you move whatever place of the exponential to the right if its positive and left if it's negative.

  1. 1.365 × 10^1
  2. You see its positive 1 hence we move one space to the right
  3. Our answer is now 13.65

You keep doing the same thing

  1. 1.365 × 10^2
  2. 136.5

Lastly

  1. 1.365 ×10^3
  2. 1365

Rate positively and give 5 stars

Least to greatest -2, -3/4, -0.45, 3%, 0.36
Crank

Answer:

\large\boxed{-2,\ -\dfrac{3}{4},\ -0.45,\ 3\%,\ 0.36}

Step-by-step explanation:

We convert some numbers to decimal fractions:

-2 = -2.00

-3/4 = -0.75

-0.45

3% = 0.03

0.36

We order

-2, -0.75, -0.45, 0.03, 0.36

\dfrac{3}{4}=\dfrac{3\cdot25}{4\cdot25}=\frac{75}{100}=0.75

other method

\dfrac{3}{4}=3:4=0.75        (use a calculator)

p\%=\dfrac{p}{100}\to 3\%=\dfrac{3}{100}=0.03
