A) No, as the equivalent one should be a simplified version of the first one- from what air e learnt. B) No, as it is 3:7, 5:9 when it has been simplified. c) Yes, as 38:19 both ave the common factor of 19, therefore, it will equal 2:1 Hope this helps

What are the solutions to the equation and check for extraneous solutions:<br><br> 16=(x-2)^2/3

GuDViN [60]

Answer:

we have x = -62 or x = 66

Step-by-step explanation:

16=(x-2)^2/3

I would take square root first

4 = (x - 2)^ (1/3)

or -4 = (x - 2)^(1/3)

.....

4^3 = x - 2

64 = x - 2

x = 66

or -4 ^3 = x - 2

-64 = x - 2

x = -62

we have x = -62 or x = 66

Krista can type 60 words per minute.She wrote an essay by hand in 5 hours, and it is now 4 pages long and has 500 words in it. S

Mumz [18]

500 divided by 60 = 8.33... (but you round it to 8)

it would take her about 8 minutes.

Find the solution set for this equation:<br> -a2+4a=0<br> (Separate the two values with a comma)

Rashid [163]

$\quad \huge \quad \quad \boxed{ \tt \:Answer }$

$\qquad \tt \rightarrow \: \{ 0,4 \}$

____________________________________

$\large \tt Solution \: :$

$\qquad \tt \rightarrow \: - {a}^{2} + 4a = 0$

$\qquad \tt \rightarrow \: - ( {a}^{2} - 4a) = 0$

$\qquad \tt \rightarrow \: {a}^{2} - 4a = 0$

$\qquad \tt \rightarrow \:a(a - 4) = 0$

The two cases are :

a = 0

or

a -4 = 0, that leads to a = 4

We can conclude :

$\qquad \tt \rightarrow \:solution \: (a) = \{ 0,4\}$
