What is 2 1/2 /1/3 ?

DanielleElmas [232]

Answer:

15/2

Step-by-step explanation:

My interpretation of your math expression is "2 1/2 divided by 1/3."

I prefer to write this as:

5 1

----- ÷ -----

2 3

which is equivalent to:

5 3

----- * ----- = 15/2

2 1

(3x-8)(2xsquared4x-9) multiply and write the result in descending order

RSB [31]

Hello there, you can proceed with the multiplication of these factors using the FOIL method (which stands for first, outer, inner and last) multiply I assume that by descending order, you mean by decreasing power. If it were so, the answer is 6(x^3)12(x^2)-16(x^2)32x-27x+72.

7.<br>(-3x³)(-2x³y⁴z)(-3z²)÷(4x³z)(-3yz) (-3xyz)

serg [7]

Answer:

$-\frac{x^2y^2}{2}$

Step-by-step explanation:

We have an extremely large equation and are asked to divide it, so let's solve it step-by-step :

Remove the parenthesis to make it easier to read :

$\frac{-3x^3 *2x^3y^4z *3z^2}{4x^3z*3yz*3xyz}$

Multiply the numerators :

$\frac{-18x^6y^4z^3}{4*3*3x^3yyzzz}$

Multiply the denominators :

$\frac{-18x^6y^4z^3}{36x^4y^2z^3}$

Apply the negative rule :

$-\frac{18x^6y^4z^3}{36x^4y^2z^3}$

Cancel the common factor which is 18 :

$-\frac{x^6y^4z^3}{2x^4y^2z^3}$

Apply the addition exponent rule :

$\frac{y^4z^3x^{6-4} }{2y^2z^3}$

Subtract :

$\frac{x^2y^4z^3 }{2y^2z^3}$

Apply the rule for y :

$\frac{x^2y^{4-2} z^3 }{2z^3}$

Subtract :

$\frac{x^2y^2z^3 }{2z^3}$

Cancel the common factor of z^3 :

$-\frac{x^2y^2}{2}$

Can you please help me?!

Nezavi [6.7K]

Answer:

d) $x=5$

Go to station 10

Step-by-step explanation:

$-\left(1+7x\right)-6\left(-7-x\right)=36$

Expand:

$-1-7x+42+6x=36$

$-x+41=36$

Subtract 41 from both sides:

$-x+41-41=36-41$

$-x=-5$

Divide both sides by -1:

$\frac{-x}{-1}=\frac{-5}{-1}$

$x=5$
