Answer: 16

Step-by-step explanation:

9,10,12,x ,20, 25 so we know the median is 14 which is the middle number.

Since the numbers are 6 it means there will be 2 middle numbers and if you divide them it will be 14.

we know one of the middle numbers is 12 and we trying to find x .

So we could use the equation x + 12 = 2(14)

x + 12 = 28

-12 -12

x= 16 so X is 16. check: 16+12=28/2 is 14.

You downloaded a video game to your computer. You have a 60-minute free trial of the game. It takes 5 1/6 minutes to set up the

igomit [66]

Answer:

Step-by-step explanation:

Given,

The time for set up the game = $5\frac{1}{6}$ minutes,

Also, the time for each level of game is $7\frac{1}{3\\}$ minutes,

If there are l levels of games,

Then the time taken in all levels of game = $(7\frac{1}{3}) l$ <em> </em>

Hence, the total time ( in minutes ) = Set up time + time in all level

= $5\frac{1}{6} +(7\frac{1}{3}) l$

We have 60-minute of free trial of the game,

So, the total time taken can not be exceed to 60 minutes,

= $5\frac{1}{6} +(7\frac{1}{3}) l\leq 60$

Which is the required inequality.

Option 'B' is correct.

3. Sophie and Jackie each have a collection of baseball cards, Jackie has 5 more cards than

IRISSAK [1]

Answer:

Sophie has 12.5 cards

Step-by-step explanation:

Let

x -----> number of cards Sophie has

y -----> number of cards Jackie has

we know that

x+y=30 -----> equation A

y=x+5 -----> equation B

Solve by substitution

Substitute equation B in equation A and solve for x

x+(x+5)=30

2x=30-5

x=12.5 cards

Note I assume the problem was invented without taking into account the result, because the amount of cards should be a whole number
