The sum of three primes is 18 so they must all be smaller than 18 as well.

Primes less than 18=2,3,5,7,11,13,17

2,3, and 13

2,5, and 11

There are two solutions...

oof

remember some rules

(a/b)(c/d)=(ac)/(bd)

$\frac{x^a}{x^b}=x^{a-b}$

$x^0=1$

$(x^a)(x^b)=x^{a+b}$

$x^{-a}=\frac{1}{x^a}$

$\frac{(7^{-3})(7^{-2})(2^0)}{(7^{-1})(7^{-4})(2^3)}=$

$\frac{(7^{-3-2})(2^0)}{(7^{-1-4})(2^3)}=$

$\frac{(7^{-5})(2^0)}{(7^{-5})(2^3)}=$

$(\frac{7^{-5}}{7^{-5}})(\frac{2^0}{2^3})=$

$(7^{-5-(-5)})(2^{0-3})=$

$(7^0)(2^{-3})=$

$\frac{1}{2^3}=$

$\frac{1}{8}$

Answer:

Step-by-step explanation:

-3.1+7-7.4x=1.5x-6(x-1.5)

We move all terms to the left:

-3.1+7-7.4x-(1.5x-6(x-1.5))=0

We add all the numbers together, and all the variables

-7.4x-(1.5x-6(x-1.5))+3.9=0

We calculate terms in parentheses: -(1.5x-6(x-1.5)), so:

1.5x-6(x-1.5)

We multiply parentheses

1.5x-6x+9

We add all the numbers together, and all the variables

-4.5x+9

Back to the equation:

-(-4.5x+9)

We get rid of parentheses

-7.4x+4.5x-9+3.9=0

We add all the numbers together, and all the variables

-2.9x-5.1=0

We move all terms containing x to the left, all other terms to the right

-2.9x=5.1

x=5.1/-2.9

x=-1+1/1.31818181818

THIS IS UR ANSWER... THANK YOUU
