Step-by-step explanation:
a)
total no. of pupils is not more than 24
therefore first equation is
(x+y) ≤ 24. ....(1)
No. of girls exceeding the no. of boys by atleast 4
(y-x) ≥ 4. .....(2)
b) Now Liza chooses 8 boys
Maximum no. of girls = ?
Using first inequality
y+8= 24 ( maximum value of less than or equal to function is equal to itself)
Therefore,
y= 24-8
=16
Minimum no. of girls = ?
Using second inequality
y-8 =4 (minimum value of greater than or equal to function is equal to itself)
Therefore,
y= 4+8
y=12
Answer:
a) 2linear inequalities
(x+y) ≤ 24
(y-x) ≥ 4
b) Max no. of girls = 16
Min no. of girls = 12
Hope it helps...
Step-by-step explanation:
can we have the picture of the graph?
2 because 1+1=2 and that’s why
3 plus 11/10 (mix number, you can get it by simplifying 300/100=3 with 11/100 left over)
311/100 (improper fraction=a fraction where the numerator is bigger than the denominator, you get it by just taking the last decimal place which is a houndredth here so you take the whole thing over 100 basically)
