Distance = 30 mi
Speed = 45 mi/h
We know that Distance = Speed x Time OR Time = Distance/Speed

Time to go to the site: T = 30/45 = 0.66667 Hour. Multiply by 60 to get it in minutes: 0.66667 x 60 = 39.9999 ≈ 40 minutes

To come back he also spent the same time or 40 minutes
To and Fro = 80 minutes or 1 H 20 minutes

Simplify 8(x + 3) - 2x 6x + 3 7x 6x + 24

Tema [17]

It would be: 8 (x + 3) - 2x
= 8x + 24 - 2x
= 6x + 24

In short, Your Answer would be 6x + 24

Hope this helps!

Area= Help me please!! Thanks :)

Savatey [412]

Answer:

80π

Step-by-step explanation:

Circle O with radius IO:

large radius = IO = 12 = R

Circle O with diameter JK

IJ = JK = KL = 2 × IO = 24

IJ = JK = KL = 24/3 = 8

small radius = 8/2 = 4 = r

The shaded area is a semicircle of radius 12 minus a semicircle of radius 4 plus two semicircles of radius 4.

That is the same as

1 semicircle of radius 12 plus 1 semicircle of radius 4

A = πR²/2 + πr²/2

A = π(12² + 4²)/2

A = 160π/2

A = 80π

4^4x-5= 8^3x-4 solve

Alexxandr [17]

$4^{4x-5}=8^{3x-4}\\\\(2^2)^{4x-5}=(2^3)^{3x-4}\qquad\text{use}\ (a^n)^m=a^{nm}\\\\2^{2(4x-5)}=2^{3(3x-4)}\iff2(4x-5)=3(3x-4)\qquad\text{use distributive property}\\\\(2)(4x)+(2)(-5)=(3)(3x)+(3)(-4)\\\\8x-10=9x-12\qquad\text{add 10 to both sides}\\\\8x=9x-2\qquad\text{subtract 9x from both sides}\\\\-x=-2\to \boxed{x=2}$
