The median is 18 because there is nine digits and if you slit them into 2 the number 18 would be in the middle

Two pieces of lengths 13/3 m and 3/5 m are cut off from a rope 15

garri49 [273]

Hello there! ;) The way you solve this type of problem is you must find common denominators. So simplify 13/3= 4 1/3. So we can do 1/3*5/5=5/15. Next we must do 3/5*3/3= 9/15. So add 5/15+9/15= 14/15. And add the 4+ 14/15= 4 14/15. So then you must subtract 15 - 4 14/15= 10 1/15 I believe. I believe 10 1/15 is the remainder of the rope. You might want to check in with someone else though.

Hope I help! :D

An amusement park charges admission plus a fee for each ride. Admission plus four ride cost $22. Admission plus seven ride cost

nignag [31]

Answer:

Admission fee charged = $3

Cost of each ride = $10

Step-by-step explanation:

Let admission fee charged by amusement park in dollars be = $x$

Let cost of each ride in dollars be = $y$

Given:

Admission plus four rides cost $22

If each ride cost in dollars = $y$

Cost of 4 rides in dollars will be = $4y$

So, the total cost in dollars will be given as = $x+4y$

So, we have

$x+4y=22$

Admission plus seven ride cost $31.

If each ride cost in dollars = $y$

Cost of 7 rides in dollars will be = $7y$

So, the total cost in dollars will be given as = $x+7y$

So, we have

$x+7y=31$

So, we have the system of equation as:

A) $x+4y=22$

B) $x+7y=31$

Solving the system by elimination method.

Eliminating $x$ by subtracting equation A from B.

$x+7y=31$

- $x+4y=22$

- - - [Sign of each term of subtract-ant gets reversed]

-----------------------------

$3y=9$

Dividing both sides by 3.

$\frac{3y}{3}=\frac{9}{3}$

∴ $y=3$

Plugging in $y=3$ in equation A.

$x+4(3)=22$

$x+12=22$

Subtracting both sides by 12.

$x+12-12=22-12$

∴ $x=10$

Thus, admission fee charged = $3

Cost of each ride = $10
