Answer: A

explanation: when it said there are 9 more children than parents in a room, it doesnt say the amount of parents, nor children, so its mainly saying that theres just more children than parents, so we mainly need to find out how many parents, and then add the amount of children, so it would most likely be A. here's how to answer the question, we need to find 2 numbers that would add up to 25, and one of the numbers has to be made with a 9 and another number, getting straight to the point, the other number would be 8, so there would be 8 parents, and 8 children, but if theres 9 more children than parents, it would be 8 + 9, which is 17, meaning that there is 17 children, then you add the amount of parents, which is 8, to 17, which adds up to 25, which is the max amount of people in the room, so the amount of children is 17, and the amount of parents is 8, If you weren't to have done that, the unknown would've been the total number of children and the total number of parents in the room.

1. Amelia can do 5 sit-ups. Her goal is to increase to 50 sit-ups by adding 5 more sit-ups to her training schedule each week. A
Olegator [25]

Answer:

(i) Equation

(ii) 10 weeks

Step-by-step explanation:

The scenario is an equation and not an inequality , this is because the number of sit - ups Amelia planned to do is specific , which is 50 , had it been the question used the word like at least , at most 50 , it would have been an inequality.

The question is an example of Arithmetic sequence

From the statement ;

The first term = 5

The common difference = 5 ( since Amelia planned to add 5 more sit - ups to her training schedule each week )

The formula for the nth term of an Arithmetic sequence is given by :

t_{n} = a + (n- 1 )d

t_{n} = 50

a = 5

d = 5

n = ?

substituting the values , we have

50 = 5 + (n - 1 ) x 5

50 = 5 + 5n - 5

50 = 5n

n = 10

Therefore , it will take Amelia 10 weeks to reach her goal of 50 sit - ups
