How do i solve x-3/18 = 12/9? (Proportions and Ratios)

neonofarm [45]

Hey there!

$\bold{x-\frac{3}{18}=\frac{12}{9}}$

Firstly, you have to simplify both sides of your equation
$\bold{x+\frac{-1}{6}=\frac{4}{3}}$
Secondly, you have to $\bold{add}$ by $\bold{\frac{1}{6}}$ on each of your sides that you're working with
$\bold{x+\frac{-1}{6}+\frac{1}{6}=\frac{4}{3}+\frac{1}{6}}$
$\bold{Cancel:\frac{-1}{6}+\frac{1}{6}}$ because it gives you the result of $\bold{0}$
$\bold{Keep:\frac{4}{3}+\frac{1}{6}}$ because it gives you the answer for $\bold{x}$
$\boxed{\boxed{\bold{Answer:x=\frac{3}{2}}}}$

Good luck on your assignment and enjoy your day!

What is the solution of the linear-quadratic system of equations? y=x^2+5x-3 y-x=2

Nady [450]

-x=-y+2
x=y-2
now substitute iin the first one
y=(y-2)^2+5 (y-2)-3
y=y^2-4y+4 +5y-10-3
y=y^2+y-9
y^2-9=0.
y^2=9
y=3

3-x=2
-x=2-3
-x=-1
x=1

the solution are x=1 and y=3
3=1^2+5 (1)-3
3=1+5-3
3=6-3
3=3

P and q are complex numbers such that ∣p∣ = 2/5 x + 2 , ∣q∣ = −3/4 x − 1 , and ∣p+q∣ = 2x + 4 .

Leya [2.2K]

Answer: (b)

Step-by-step explanation:

Given

$\left | p\right |=\dfrac{2}{5}x+2$

$\left | q\right |=\dfrac{-3}{4}x-1$

$\left | p+q\right |=2x+4$

for two complex number, $z_1,z_2$

Apply the above the property

$\Rightarrow 2x+4\leq \dfrac{2}{5}x+2-\dfrac{3}{4}x-1\\\\\Rightarrow 2x+4\leq \dfrac{8x-15x}{20}+1\\\\\Rightarrow 2x+3\leq -\dfrac{7x}{20}\\\Rightarrow x\leq -\dfrac{60}{47}$

Also, the absolute value of each complex number must be greater than or equal to zero

$\text{Case-1}\\\\\Rightarrow \dfrac{2}{5}x+2\geq 0\\\\\Rightarrow x\geq -5\\\\\text{Case-2}\\\\\Rightarrow -\dfrac{3}{4}x-1\geq 0\\\\\Rightarrow x\leq -\dfrac{4}{3}\\\\\text{Case-3}\\\\\Rightarrow 2x+4\geq 0\\\Rightarrow x\geq -2$

Taking the intersection of the above values of x, we get

$x\in [-2,-\dfrac{4}{3}]$
