(x+4)^2 / 9 - (y+3)^2 / 16 = 1


a^2 = 16 and b^2 = 9

a = +4 and -4

b = +3 and -3


Center is (-4, -3)

Vertices is (-4 + a, -3) and (-4 - a, -3)

Vertices is (-1, -3) and (-7, -3)

12 grapes cost 90 $how many can bought in 40$
likoan [24]

Let x = the amount of grapes that can be bought for 0.40.


Note: By 90 I assume you mean 90 cents. The same for 40.


12/x = 0.90/0.40


0.90x = 12(0.40)


0.90x = 4.80


x = 4.80 ÷ 0.90


x = 5.33333


We can round the decimal to the ones place to get 5 grapes.

If 2x + 5 = 82, then 12x = ?<br> A 5<br> B<br> 10<br> C 15<br> D 20
KengaRu [80]

Answer:

2x= 38.5

Step-by-step explanation:

I'm not sure where u got 12x but 2 x = 38.5:

2x + 5 =82

subtract 5 for 82

2x = 77

77 divided by 2 is 38.5

x = 38.5

hope this helps :)

5 &lt; 4x = 2&gt; 3x PLEASE HELP
Galina-37 [17]
Looks fishy to me, the way this problem combines <, = and > symbols.

But anyway.  Subtract 3x from both sides.  You'll get

5 < x = 2 > 0      2 > 0 is true, but that's a different type of math problem (true or false).    If you decide to substitute '1' for 2 > 0, then the "1" says "TRUE."

Then 5 < x = true, so you must find x values that are larger than 5.

That would be (5, infinity)

Please go back and ensure that you have copied down the original problem exactly as it appears.
