Solve for x 3x-4=26 i need help

1 answer:

5 0

Answer; x=10

add the 4 and 26 which is 30, so the equation then would be; 3x=30 and that’s how you get 10 as you answer.

hope this helped you out!

A helicopter is told taht there is another helicopter 300 feet below at 76°angle of depression. Approximately how far apart are

anygoal [31]

Answer: $309\ ft$

Step-by-step explanation:

Given

Vertical distance between two helicopters is 300 ft

angle of depression is $76^{\circ}$

Suppose the distance between the helicopters is d

from the figure, we can write

$\Rightarrow \sin 76^{\circ}=\dfrac{300}{d}\\\\\Rightarrow d=\dfrac{300}{\sin 76^{\circ}}\\\\\Rightarrow d=309.18\approx 309\ ft$

Plz Help me!!!<br> will mark brainliest!!

Ksju [112]

Answer:

3x² * (6x² + 4x - 8) = 18x⁴ + 12x³ - 24x²

2x * (9x³ + 6x² - 12x) = 18x⁴ + 12x³ - 24x²

x² * (18x² + 12x - 24) = 18x⁴ + 12x³ - 24x²

6x² * (3x² + 2x - 4) = 18x⁴ + 12x³ - 24x²

Step-by-step explanatation:

Let's set unknown variables as y (and y₁, y₂, etc)

Question 1:

y * (6x² + 4x - 8) = 18x⁴ + 12x³ - 24x²

So, divide both sides by (6x² + 4x - 8)

y = 3x²

Question 2:

2x * (9x^y₁ + y₂*x^y₃ - y₄*x) = 18x⁴ + 12x³ - 24x² '

Divide both sides by 2x.

(9x^y₁ + y₂*x^y₃ - y₄*x) = 9x³ + 6x² -12x

y₁ = 3, y₂ = 6, y₃ = 2, y₄ = 12

Question 3:

x^y * (18x² + 12x - 24) = 18x⁴ + 12x³ - 24x²

Divide both sides by (18x² + 12x - 24)

x^y = x²

Question 4:

y₁ * x^y₂ * (3x² + 2x - 4) = 18x⁴ + 12x³ - 24x²

Divide both sides by (3x² + 2x - 4)

y₁ * x^y₂ = 6x²

y₁ = 6, y₂ = 2

I hope this helps! Feel free to ask any questions!

What is 24x128725(7x782)/199+4+23

ryzh [129]

Answer:

$\bold{\frac{8455687800}{113}}$

Step-by-step explanation:

$\frac{24\times \:128725\left(7\times \:782\right)}{199+4+23}$

$\mathrm{Add\:the\:numbers:}\:199+4+23=226$

$=\frac{24\times \:128725\times \:7\times \:782}{226}$

$\mathrm{Factor\:the\:number:\:}\:24=2\times \:12$

$=\frac{2\times \:12\times \:128725\times \:7\times \:782}{226}$

$\mathrm{Factor\:the\:number:\:}\:226=2\times \:113$

$=\frac{2\times \:12\times \:128725\times \:7\times \:782}{2\times \:113}$

$\mathrm{Cancel\:the\:common\:factor:}\:2$

$=\frac{12\times \:128725\times \:7\times \:782}{113}$

$\mathrm{Multiply\:the\:numbers:}\:12\times \:128725\times \:7\times \:782=8455687800$

$\bold{=\frac{8455687800}{113}}$

$\mathrm{Decimal:74829095.57522}$
