Answer:
a) Here we have:
"In Family A, the youngest child is 7 years younger than the oldest, who is 18"
Let's define:
Y = age of the youngest child.
O = age of the oldest child.
Then we know that:
Y = O - 7
O = 18
Then we can replace the second equation into the first one:
Y = 18 - 7 = 11.
b) Here we have:
"In Family B, the middle child is 5 years older than the youngest child."
Let's define:
Y = age of the youngest child.
M = age of the middle child.
Here we have only one equation:
M = Y + 5.
I’m having a hard time understanding your question
Answer:
9 (make sure to place the currency symbol (e.g. £ or $) beside your answer, otherwise it may be counted as incorrect).
Step-by-step explanation:
- If one adult went and the adult tickets cost 14, we can subtract 14 from 59 to see the total cost of the children's five tickets:
59 - 14 = 45
- Because there are 5 children, you then divide that value by 5 in order to find out the cost for one child and, ultimately, the cost of each child's ticket: 45 ÷ 5 = 9
- The cost of each child's ticket is therefore 9
