Hey there!
First, we will do the subtraction with the two like terms on the left. I know they're like terms because although they have different coefficients, they have the same variable.
We have:
2n=4
Divide both sides by 3 to get:
n = 2
Hope this helps!

A card is drawn from a standard deck of 5252 playing cards. What is the probability that the card will be a heart and not a club
ale4655 [162]

Answer:

The probability of choosing a heart and not a club is

P =  0.1875

Step-by-step explanation:

There are 13 hearts in a deck of 52 cards. The probability that the chosen card will be a heart is given by

Probability = favorable outcome/ Total number of outcomes

P= 13/52= 1/4

There are 13 clubs in a deck of 52 cards.

The probability of not choosing a club would be

P = 52-13/52= 39/52= 3/4

So the  combined probability of choosing a heart and not a club is

P = 1/4 * 3/4= 0.25 * 0.75= 0.1875

Answer:

<em>y = </em>\frac{3}{7}<em> x + 1  </em>

If AB ⊥ CD , then ( m_{AB} ) ( m_{CD} ) = - 1

y = - \frac{7}{3} x + 3

y - ( - 4) = \frac{3}{7} ( x - 7) ⇔ <em>y = </em>\frac{3}{7}<em> x + 1 </em>
