Answer:

$x = 6$

Step-by-step explanation:

$\frac{2}{3} x + 4 = 8 \\ \frac{2x}{3} = 8 - 4 \\ \frac{2x}{3 } = 4 \\ 2x = 4 \times 3 \\ 2x = 12 \\ x= 6$

Answer:

$x=6$

Step-by-step explanation:

$2/3x+4=8\\$

Subtract 4 from both sides

$2/3x=4$

Multiply both sides by 3

$6/3x=12\\2x=12$

Divide both sides by 2

$x=6$

A burst of electromagnetic radiation has a frequency of 1 exahertz. One exahertz equals 10^12 megahertz. Each megahertz is equal

den301095 [7]

Answer:

The frequency of the burst of electromagnetic radiation which equals 1 exahertz = 10¹⁸ hertz.

Step-by-step explanation:

Since the frequency of the burst of electromagnetic radiation is 1 exahertz, and 1 exahertz = 10¹² megahertz. So, the frequency of radiation is 10¹² megahertz. Also 1 megahertz = 10⁶ hertz. So, 10¹² megahertz = 10¹² × 1 megahertz = 10¹² × 10⁶ hertz = 10¹² ⁺ ⁶ hertz = 10¹⁸ hertz.

So the frequency of the burst of electromagnetic radiation which equals 1 exahertz = 10¹⁸ hertz.

Find the length of the third side. If necessary, round to the nearest tenth. 25 20

Komok [63]

Answer:

Step-by-step explanation:

$using \: pythagoras \: theorem \\ let \: the \: unknown \: side = x \\ 25 {}^{2} = x {}^{2} + 20 {}^{2} \\ 625 = x {}^{2} + 400 \\ x {}^{2} = 625 - 400 \\ x {}^{2} { = 225} \\ x = \sqrt{225} \\ x = 15 \\ lenght \: of \: the \: third \: side = 15$
