Answer:
y = 218
Step-by-step explanation:
Mean = (Sum of all numbers)/(How many numbers present)
27 = (20 + 2y + 25 + y + 30)/27
27 = (3y + 75)/27
3y + 75 = 729
3y = 729 - 75
3y = 654
y = 218
I’m canadian so I’m not quite sure how the money itself works, but I can explain how to do them. The easiest way is to divide each option by the number of items per price. For example, in A option 1 is already 1 ticket/ £8 whereas in the second it’s 3 tickets/ £20. So divide both the 3 and the £20 so you get the price per individual ticket. In the end you get 1 ticket/ £6.66 meaning it is a better deal than option 1.
Answer:
c is true
Step-by-step explanation:
Answer:
Diego is 14 years old.
Sister is 19
Step-by-step explanation:
x = Diego's age
<u>x</u><u> </u><u>+</u><u> </u><u>2</u><u>4</u>
2x-9 = 2
First to get rid of the fraction we multiply each side by 2
2(2x-9) = 2((x+24)/2)
4x-18 = x+24
The we isolate x
4x-18 = x+24
<u>-x+18 -x+18</u>
<u>3x</u> = <u>42</u> Now we divide each side 3
3 3
x = 14
So Diego is 14
Now we can solve for his sister. We can use one of the two equations from earlier to do this.
Plug 14 in for x and then solve for his sister
2(14)-9
28-9
19
His sister is 19
