Answer:
(1, 4)
Step-by-step explanation:
(x + 1 < 5) is solved by subtracting 1 from both sides of this inequality:
x < 4.
(x - 4 > -3) is solved by adding 4 to both sides: x > 1.
The solution of (x + 1 < 5) ∩ (x - 4 > -3) is thus (1, 4).
To win a lollipop players have to score exactly 7.
Each lollipop costs the school 30p.
How much should the school expect to raise for charity

Answer:
£15
Step-by-step explanation:
First lets find out how much the school earns when 120 play the game.
20p=£0.20 pounds
120 x 0.2= £24 that the school earns
Now to find how much the school needs to pay.
There are 3 out of 12 spaces on the possibility space that are 7's so 3/12 win which simplifies to 1/4.
1/4 of 120= 30 people who win the game
30p=£0.30 pounds
30 x 0.3= £9
What the school earns for people playing the game - money spent on lollipops= money raised for charity
£24-£9=£15
So the answer is £15. Hope this helps and is clear enough.
B) 2x-3y=3
C) 2x+y=1
D) x+2y=1
The requried 200 divided by 30 is equal to 6.67 (rounded to two decimal places).
In mathematics, the division is an arithmetic operation that involves splitting a quantity into equal parts or groups. It is the inverse of multiplication, and it is used to find out how many times one number can be divided by another.
Here,
200 divided by 30 is given as,
= 200/30
= 20/3
