8 0

$x:(x+4) = 3:5\\\\\implies \dfrac x{x+4} = \dfrac 35 \\\\\implies 5x = 3x +12\\\\\implies 5x -3x = 12\\\\\implies 2x = 12\\\\\implies x = \dfrac{12}2 = 6$

Answer:

X=6

Step-by-step explanation:

X divided by(x+4)=3 divided by 5, x=-4

cross multiply

5x=3(x+4)

Remove parentheses

5x=3x+12

move the variable to the left

5x-3x=12

collect like terms

2x=12

divide both sides

x=6

C=wtc/1000 solve for w

Nutka1998 [239]

For this case we have the following equation:
$C = \frac{wtc}{1000}$
To clear w, we must follow the following steps:
1) The value of t multiplied by c pass to divide the other side of the equation:
$\frac{w}{1000} = \frac{C}{tc}$
2) the value of 1000 is passed to multiply to the other side of the equation:
$w = \frac{1000C}{tc}$
Answer:
The cleared equation for w is:
$w = \frac{1000C}{tc}$

HELP PLS ASAP!!

DedPeter [7]

Answer:

cos^(-1)(12/13) = 22.62°

Step-by-step explanation:

Inverse trig functions are used to find angles. I was taught SOH CAH TOA: sine = opposite/hypotenuse, cosine = adjacent / hypotenuse, tan = opposite / adjacent.

Here, we have an adjacent side length and the hypotenuse. So we use inverse cosine.
