Answer:
x= 6- 3y/2 y= 4- 2x/3
Step-by-step explanation:
Answer:Number of children = 2 and number of adults = 9 attended the play
Step-by-step explanation:
Step 1
Let the number of children be represented as x
and the number of adults in the group be represented as as y
such that the total number of the group that went to the play
= x+y=11--- equation 1
And the total cost paid for the play will be expressed as
15x+ 22y= 228------ equation 2
Step 2-- Solving
x+y=11--- equation 1
15x+ 22y= 228------ equation 2
B y elimination method, multiply equation 1 by 15 to give equation 3 and then subtract from equation 2
15x+ 22y= 228------ equation 2
15x+15Y= 165----- equation 3
7y=63
y= 63/7= 9
y= adults = 9
therefore x = number of children will be
x+y=11
x+ 9=11
x= 11-9= 2
In the group that attended the play, Number of children = 2 and number of adults = 9

What else can measure
The question has missing options. So, I will give a general explanation.
Using the attached image as a point of reference.
Given that:
The value of b is calculated as:
Because b and 
are vertically opposite angles
<em>This gives:</em>
<em></em>
<em></em>
<em></em>
<em>So, one possible answer to the question is a vertically opposite angle</em>
