<span>x=theta
so we know that tanx = sinx/cosx
therefore is tanx = 4/3 and sinx = -4/5
we can set up an equation to find cosx
so 4/3 = (-4/5)/cosx
we can multiply x to have cosx(4/3)=-4/5
we can then divide 4/3 over so we have
cosx = (-4/5)/(4/3)
therefore, cos x = -3/5
</span>
there is the answer

i hope this help

An excursion party had $2.00 to pay in total, but before the bill was paid 10 people from the party went away, and those that re

KatRina [158]

Answer:

20 people

Step-by-step explanation:

Let x be the number of people initially. We can find the amount each of them has to pay at first

2 / x

But when 10 people walk away, the remaining (x - 10) has to pay 10 cents more to get the same total of $2. This would means

$(\frac{2}{x} + 0.1)(x-10) = 2$

From here we can perform cross multiplication

$2 - 20/x + 0.1x - 1 = 2$

$0.1x - 20/x - 1 = 0$

Multiply both sides by 10x:

$x^2 -10x - 200 = 0$

$x= \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$

$x= \frac{10\pm \sqrt{(-10)^2 - 4*(1)*(-200)}}{2*(1)}$

$x= \frac{10\pm30}{2}$

x = 20 or x = -10

Since x can only be positive we will pick x = 20

lozanna [386]

Answer:

x = -0.3

Step-by-step explanation:

You can substitute y in 2x – 4y = 3, to solve for x.

How to solve for x:

2x - 4(3x) = 3 (Simplify)

2x - 12x = 3 (Simplify)

-10x = 3 (Divide by -10)

x = -0.3
