Solve for x (-4/3) x - 6 = -26 A. −27 B. −15 C. 15 D. 27

andre [41]

$- \dfrac{4}{3} x - 6 = -26$

//Add 6 to both sides:
$- \dfrac{4}{3} x = -20$

//Multiply by -1 on both sides:
$\dfrac{4}{3} x = 20$

Multiply by 3 on both sides:
$4x = 60$

Divide by 4 on both sides:
$x = 15$

Solve: 1 5 x = -10 A) -50 B) -20 C) -2 D) 2

Inessa [10]

Answer:

In order to find x, you will have to use the operation of equality to isolate the x.

$15x=-10$

Now, use the division property of equality and divide by 15 on both sides. This will cancel out the 15 on the left side of the equation and isolate the x completely.

$-10/15=\frac{-2}{3}$

Thus, this is your answer:

$\boxed{x=-\frac{2}{3} }$

What is the solution to the equation 13.7y – 10.6 = 6.2y + 19.4?

Lyrx [107]

Answer:

Step-by-step explanation:

Simplifying

13.7y + -10.6 = 6.2y + 19.4

Reorder the terms:

-10.6 + 13.7y = 6.2y + 19.4

Reorder the terms:

-10.6 + 13.7y = 19.4 + 6.2y

Solving

-10.6 + 13.7y = 19.4 + 6.2y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-6.2y' to each side of the equation.

-10.6 + 13.7y + -6.2y = 19.4 + 6.2y + -6.2y

Combine like terms: 13.7y + -6.2y = 7.5y

-10.6 + 7.5y = 19.4 + 6.2y + -6.2y

Combine like terms: 6.2y + -6.2y = 0.0

-10.6 + 7.5y = 19.4 + 0.0

-10.6 + 7.5y = 19.4

Add '10.6' to each side of the equation.

-10.6 + 10.6 + 7.5y = 19.4 + 10.6

Combine like terms: -10.6 + 10.6 = 0.0

0.0 + 7.5y = 19.4 + 10.6

7.5y = 19.4 + 10.6

Combine like terms: 19.4 + 10.6 = 30

7.5y = 30

Divide each side by '7.5'.

y = 4

Simplifying

y = 4

sin(x) = opp/hyp
cos(x) = adj/hyp
tan(x) = opp/adj

sin(x) = 3.9/8.1
sin(x) = 0.481

Inverse sin of 0.481 = 28.8 degrees

Each answer should be between 0 and 90 :)
