The perimeter of the rectangle below is 84 unit . Find the length side of XY

lesya [120]

Answer:

25 unit

Step-by-step explanation:

See attachment for the missing figure.

Assuming the complete question is:

Side UY = 4z-1

Side UV = 5z+3

Perimeter of rectangle is given by:

2UY+2UV=P

2(4z-1)+2(5z+3)=84

8z-2+10z+6=84

18z+4=84

18z = 84 -4 =>

18z = 80

z= 4.45 unit

Side UV = 5z+3 => 5(4.45) + 3

Side UV ≈ 25 unit

SInce, Side UV = Side XY

Side XY≈ 25 unit

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
