Answer:

a) y = [tex]\frac{1}{2} x[/tex]

b) y = [tex]\frac{5}{2}[/tex]

Step-by-step explanation:

I. If y = 9 and x = 18

  so x is double value of y or y * 2

  y will be half of x value

 that makes y = [tex]\frac{1}{2}[/tex] x

II. If x = 5, replace x with 5

    y = [tex]\frac{1}{2}[/tex] (5)

    y = [tex]\frac{5}{2}[/tex]

Answer:

(a).

[tex]{ \boxed{ \sf{y = \frac{1}{2}x }}}[/tex]

b).

[tex]{ \boxed { \sf{y = \frac{5}{2} }}}[/tex]

Step-by-step explanation:

explanation for (a):

[tex]{ \sf{y \: \alpha \: x}} \\ { \sf{y = kx}} [/tex]

when y is 9, x is 18

[tex]{ \sf{9 = (k \times 18)}} \\ { \sf{k = \frac{1}{2} }}[/tex]

therefore equation is:

[tex]{ \sf{y = \frac{1}{2}x }}[/tex]

explanation for (b):

when x is 5:

[tex]{ \sf{y = \frac{1}{2}x }} \\ \\ { \sf{y = \frac{1}{2} \times 5}} \\ \\ { \sf{y = \frac{5}{2} }}[/tex]

The probability of picking a dime from the coins in his pocket is 1/13

1 penny = 1 cent

Hence, 100 pennies = $1

1 nickel = 5 cent

20 nickels = $1

1 dime = 10 cent

10 dime = $1

This means that :

Eduardo has :

Total coins = (100 + 20 + 10) = 130 coins

Recall :

Probability = required outcome / Total possible outcomes

P(dime) = number of dimes / total coins

P(dime) = 10 / 130 = 1/13

Hence, the probability of picking a dime = 1/13

Step-by-step explanation:

do math

x = (1814.75 - 1168.50)/(58.75)

==============================================

Explanation:

x = number of players

58.75x = cost of all the meals for those x players

58.75x + 1168.50 = adding on the cost of the bus

58.75x + 1168.50 = 1814.75

----------

Let's solve for x.

58.75x + 1168.50 = 1814.75

58.75x = 1814.75 - 1168.50

x = (1814.75 - 1168.50)/(58.75)

x = 11

This means 11 players can go on the trip.

1 player = $58.75 in meals

11 players = 11*58.75 = $646.25 total in meal costs

646.25 +  1168.50 = 1814.75

So this confirms the answer.

The correct equation to determine the number of players (x) the team can bring to the tournament is x = (1814.75 - 1168.5) / 58.75.So, the correct answer is B. x = (1814.75-1168.5)/58.75

The amount raised by the lacrosse team is $1814.75. They spent $1168.50 on the bus rental and budgeted $58.75 per player for meals. Let's break down the expenses:

Total expenses = Bus rental cost + (Number of players * Meal cost per player)

Total expenses = $1168.50 + (x * $58.75)

The equation that represents the total expenses in terms of the number of players (x) is: Total expenses = $1168.50 + $58.75x

Since the team raised $1814.75, we can set up the equation:

Total expenses = Amount raised

$1168.50 + $58.75x = $1814.75

Now, let's solve for x:

$58.75x = $1814.75 - $1168.50

$58.75x = $646.25

Dividing both sides by $58.75:

x = $646.25 / $58.75

x = 11

So, the correct equation to determine the number of players (x) the team can bring to the tournament is: B. x = (1814.75 - 1168.5) / 58.75

like 4/5× 5/5 which would have a fraction of 20/25 which would be equal to 4/5, its just bigger and more complicated really.

Answer:

6, because the slope is equivalent to the value of a / 4. you see the run is 4, double of two, so the answer that makes sense is 6 as it is double of three.

Two or more points are said to be coplanar if they all lie on the same plane.

Based on the given diagram, we can see that the points N, R, S, and W all lies on the same plane A. Due to this fact, we can conclude that N, R, S, and W are coplanar.

Assuming any of the four points fall outside plane A, then we can say they are not coplanar.

Based on the explanation above, we can conclude that points N, R, S, and W all lie on the same plane.

Answer:

The sum of 5 numbers with an average of 5 more than 5 is 50

Step-by-step explanation:

Let the first five letters of the alphabet be equal to the 5 numbers being summed.

Let the average be represented by the following equation:

[tex]\frac{a + b + c + d + e}{5} = 10[/tex]

To find the sum, we should get rid of the denominator. To do that we multiply 5 on both sides

[tex]\frac{a + b + c + d + e}{5} (5) = 10(5)\\a + b + c + d + e = 50[/tex]

Therefore, we see to it that the sum of the 5 numbers is 50.
