What value of x is the solution to the equation −3/2x−3/4=−1/5 ?

Ray Of Light [21]

Answer:

$\Longrightarrow: \boxed{\sf{x=-\dfrac{11}{30} }}$

Step-by-step explanation:

Isolate the term of x from one side of the equation.

First, add by 3/4 from both sides.

$\sf{-\dfrac{3}{2}x-\dfrac{3}{4}+\dfrac{3}{4}=-\dfrac{1}{5}+\dfrac{3}{4} }$

Solve.

⇒ = -3/2x=11/20

Then, you multiply by 2 from both sides.

2(-3/2x)=11*2/20

Solve.

11*2/20

11*2=22

22/20

Common factor of 2.

11/10

-3x=11/10

Divide by -3 from both sides.

$\sf{\dfrac{-3x}{-3}=\dfrac{\dfrac{11}{10}}{-3}}$

Solve.

$\Longrightarrow:\boxed{\sf{x=-\dfrac{11}{30} }}$

Therefore, the correct answer is D. x=-11/30.

I hope this helps! Let me know if you have any questions.

given the first term and the common difference of an arithmetic sequence find the 52nd term and the explicit formula. did I do t

Andreyy89

Answer:

41) A52 = -10206

42) - 320

43) -276

44) 10200

Step-by-step explanation:

41) A1 = -6, D = -200

An = a1 + (n - 1) d

We have to use the above formula to find the 52nd term.

A52 = -6 + (52 - 1) -200

= -6 + 51*-200

= -6 - 10200

A52 = -10206

42)

37 + -7(52 -1)

37 + -7(51)

= 37 - 357

= - 320

43)

30 + -6(52 -1 )

= 30 + -6(51)

= 30 - 306

= -276

44)

0 + 200(52 -1)

= 200(51)

= 10200

Thank you.

Hope you will understand the concept.

Thank you.
