3/x+2 = 2/x−1 pleasee help

olga_2 [115]

So you have:
$\frac{3}{x} + 2 = \frac{2}{x} - 1
$

1) Start off by multiplying both sides by x to simplify the problem:
$\frac{3}{x} + 2 = \frac{2}{x} - 1 \\
x(\frac{3}{x} + 2) = (\frac{2}{x} - 1)x\\
3 + 2x = 2 - x
$

2) Now isolate the x by moving all terms with x onto one side and all other terms onto the other side:
$3 + 2x = 2 - x\\
3x = -1$

3) Finally, divide by 3 on both sides to find the value of x:
$3x = -1\\
x = \frac{-1}{3}$

Answer:

x = 8.3 is the value of x.

Step-by-step explanation:

Given:

Let Δ ABC be a Right angle Triangle at ∠ C = 90°

AB = x

BC = 6

m∠ B = 44°

To Find:

x = ?

Solution:

We apply Cosine Rule

{tex}\cos B = \frac{\textrm{side Adjacent to angle B}}{Hypotenuse} \\{/tex]

Substituting the given values we get

$\cos B = \frac{BC}{AB}\\\\\cos 44 = \frac{6}{x}\\\\0.719=\frac{6}{x}\\\\\therefore x=\frac{6}{0.719} \\\\\therefore x=8.3......(nearest\ tenth)$

The value of x is

x = 8.3

How do I solve: 15 - w/4 = 28 (this is 2 step equations)

kenny6666 [7]

First we need to isolate the variable so we add 15 to both sides which is
w/4=43 then we need to multiply by 4 to both sides so its 4w=172
then divide by 4 which is 43 so the answer is w=43

murzikaleks [220]

$4.04 is the answer.

30 x $6.00 = $180

70 x $3.20 = $224

$180 + $224 = $404

404/100 = $4.04
