1 + (-5/8) = 3/8

Explanation: If the coffee wasn’t drank it would’ve been at fraction 1 (or 100%)

Since he drank 5/8 of it. The coffee left is now 1-(5/8)

But since the question has asked to give the equation in addition format. Put a plus sign in between the two.

Therefore,
1 + (-5/8)

Solve it,
= 1-(5/8)
= (8-5)/8
= 3/8

Hence the equation is:

1 + (-5/8) = 3/8.

Given z1 = -3

trasher [3.6K]

Answer:

See explanation

Step-by-step explanation:

The given complex number are:

$z_1=-3\sqrt{3}+3i$

and

$z_2=6\cos 150\degree+6i\sin 150\degree$

When we rewrite $z_1=-3\sqrt{3}+3i$ in complex form, we obtain;

$z_1=r(\cos \theta+i\sin \theta)$

where

$r=\sqrt{(-3\sqrt{3})^2+3^2 }=\sqrt{36}=6$

and

$\theta=tan^{-1}(\frac{y}{x})$

$\implies \theta=tan^{-1}(\frac{-3\sqrt{3}}{3})=150\degree$

Hence,

$z_1=6(\cos 150\degree+i\sin 150\degree)$

$z_1=6\cos 150\degree+6i\sin 150\degree$

Hence

$z_1=z_2$

What is the value of x?

MariettaO [177]

x = 36.2 .
______________________________________________

Explanation:
________________________________________________
2x - 1 + 3x = 180 ;

Combine the "like terms" on the left-hand side of the equation:
________________________________________________
+2x + 3x = + 5x ;
_____________________________________
And rewrite:
_____________________________________
5x - 1 = 180 ;
_____________________________________
Add "1" to each side of the equation:
_____________________________________
5x - 1 + 1 = 180 + 1 ;
_____________________________________
5x = 181 ;
_____________________________________
Divide EACH SIDE of the equation by "5" ;
_____________________________________
5x / 5 = 181 / 5 ;
_____________________________________
to get:
_____________________________________
x = 36.2 .
_____________________________________
