Mr. Wallace needs to divide his class or 23 students into 9 groups. Each group can have two or three students. If a is the numbe

IRINA_888 [86]

Answer:

d) Mr.Wallace can use the following equations:

a + b = 9

2 a + 3 b = 23

Step-by-step explanation:

Here, the total number of students = 23

Number of groups = 9

Each group can have 2 or 3 students.

a is the number of groups of 2.

⇒ Total students in a groups = a x (Number of student in each group)

= a x 2 = 2 a

b is the number of groups of 3

⇒ Total students in b groups = b x (Number of student in each group)

= b x 3 = 3 b

So, according to the question:

Total number of groups formed = 9

⇒ a + b = 9

Total number of students = 23

or Number of students in ( a group + b group ) = 23

⇒ 2 a + 3 b = 23

Hence, Mr.Wallace can use the following equations:

a + b = 9

2 a + 3 b = 23

Renee is buying Halloween candy. She wants to buy candy bars and lollipops and spend no more than $28. Each candy bar costs $0.4

aivan3 [116]

The inequality that represents the possible combinations of candy bars and lollipops that he can buy is given by:

$0.45x + 0.25y \leq 28$

<h3>What is the inequality that models this situation?</h3>

The total price can be no more than $28, hence:

$T \leq 28$

Each candy bar costs $0.45 and each lollipop costs $0.25. x is the number of candy bars and y of lollipops. Hence, the total price is given by:

T = 0.45x + 0.25y.

Hence, the inequality that models the situation is:

$0.45x + 0.25y \leq 28$
