Answer:

Kim is 43 years old, and Jordan (7 years older) is 50 years old.

Step-by-step explanation:

Representation:

Kim's age is x

Jordan's is x + 7

Then 4(x + 7) = 200, and 4x + 28 = 200.

Simplifying, 4x = 172.  Dividing both sides by 4 to isolate x, we get:

x = 172/4 = 43

Thus, Kim is 43 years old, and Jordan (7 years older) is 50 years old.

A card is drawn at random from a well-shuffled pack of 52 cards. Find the probability that the card drawn is neither a red card
Reil [10]
Number of red cards including 2 red queens = 26
Number of black queens = 2
Therefore, number of red cards including 2 red queens and 2 black queens = 26 + 2 = 28
Number of cards neither a red card nor a queen = 52 - 28 = 24

P  =  \frac{ Number \: of \: favourable \: outcomes}{ Total \: numer \: of \: possible \: outcomes}

P (neither \: a \: red \: nor \: a \: queen \: card \: ) =  \frac{24}{52}  =  \frac{6}{13}

Casey wants to buy a gym membership. One gym has a $150 joining fee and cost $35 per month. Another Jim has no joining fee and c
Katyanochek1 [597]

Answer:

After 6 months, Casey would pay $360 to join either gym.

Step-by-step explanation:

At the first gym, the cost is $35 per month in addition to a $150 joining fee.  So, the equation based on 'x' number of months and a total cost of 'c' is:

c = 35x + 150

At the second gym, the cost is just $60 per month.  So, the equation based on 'x' number of months and a total cost of 'c' is:

c = 60x

Since you want to find the number of months 'x' it would take until Casey would pay the same amount to be a member of either gym, you can take the two equations and set them equal to each other:

35x + 150 = 60x

Subtract 35x from both sides: 35x - 35x + 150 = 60x - 35x or 150 = 25x

Divide both sides by 25: 150/25 = 25x/25 or x = 6

So, after 6 months, the cost would be same.  The find the cost, replace 'x' with 6 in one of the equations:  c = 60(6) = $360.
