$7 - 5n = 42$

$- 5n = 35$

$n = - 7$

Since a negative times a positive makes a negative you can change your equation to 7 - 5n=42. You can now subtract 7 from both sides to get -5n = 35. Next get divide -5 on both sides giving you n = -7.

Solve each proportion: 4/15=x/75 and t/9=35/6 how do you work these please show steps thank you

BARSIC [14]

Multiplied by the cross

4/15 = x /75

15•x=4•75
15x=300
x= 300 : 15
x=20

t/9 = 35/6

9•35 = t•6
315 =6t
315 : 6 = t

52,5 = t

The price of a Panasonic 3D flat screen television decreased by 1∕5. If the original price was $1,500, what is the price today?

marin [14]

1,500/5=300.

Therefore 1/5 of $1,500 is $300.

$1,500 - $300 = $1,200.

So its price today would be $1,200.

Cards are dealt, one at a time, from a standard 52-card deck. a if the first 2 cards are both spades, what is the probability th

ratelena [41]

So we already drew two cards and both of them are spades. So that means there are 50 cards and 11 spades left.

Then third card being spades would be 11 / 50

Now there are 10 spades and 49 cards left.
So the probability for fourth card would be 10 / 49

Fifth card would be 9 / 48.

So the probability of next three cards being spades would be
$\dfrac{11}{50}\cdot\dfrac{10}{49}\cdot\dfrac9{48}=\dfrac{33}{3920}\approx\boxed{0.00842}$

Hope this helps.
