Answer:
no of 5 kg disks is 3, and no of 2 kg disks is (10-3) i.e. 7
Step-by-step explanation:
Let the no of 2kg disks be a.
Let no of 5 kg disks be b.
2a+5b=29
a+b=10
Using substitution, we have
2(10-b) + 5b=29
20-2b+5b=29
20+3b=29
3b=9
b=3
So no of 5 kg disks is 3, and no of 2 kg disks is (10-3) i.e. 7

Answer:
8 ≤ $45
Step-by-step explanation:
Given:
People younger than 8 get in for $45.
Now we can assume that the cost given might be to enter in the garden or might be in fair or might be at museum or might be at a zoo which is $45 for people which are younger than 8.
Now we can say for people younger than 8 means people or children who are of 8 years or who are below 8 years or say less than 8 years.
Hence we can say people who are less than or equal to 8 get in for $45
So the inequality equation becomes.
8 ≤ $45
