We have the price of a senior ticket is $4 and the price of a child ticket is $7
Step-by-step explanation:
We can form two equations, let the price of a senior ticket be s and the price of a child ticket be c.
We have from day 1:
A: 3s + 9c = 75
And from day 2:
B: 8s + 5c = 67
Now we can rewrite A as:
A: 24s + 72c = 600
And can rewrite B as:
B: 24s + 15c = 201
Now A-B can be written as:
A-B: 57c = 399
So c = 7
Now substituting this back into A we get:
A: 3s + 63 = 75
A: 3s = 12
So s = 4
We have the price of a senior ticket is $4 and the price of a child ticket is $7

Answer:
value of QZ = 8 units and QM = 12 units.
Step-by-step explanation:
Given: In triangle PQR has medians QM and PN that intersect at Z.
If ZM = 4 units.
In the figure given below; second median divided the two triangles formed by the first median in the ratio 2:1.
We have to find the value of QZ and QM;
QZ:ZM = 2: 1
⇒
Substitute the value of ZM =4 units and solve for QZ;
Multiply both sides by 4 we get;
Now, calculate QM;
QM = QZ+ZM = 8 + 4 = 12 units.
Therefore, the value of QZ and QM are; 8 units and 12 units
The inequality that shows the scores Miriam could get to pass her math class is
<em><u>Solution:</u></em>
Given that To pass this year's math class, Miriam needs to earn at least an 82%
To find: Inequality that shows the scores Miriam could get to pass her math class
Let "x" be the Miriam's score in the math class
Given she should score at least 82 %
Therefore, we can frame a inequality as:
Here we used "greater than or equal to" , because she can score 82 % or more than 82 % also
The maximum score is 100 %
Hence we can frame a inequality as:
Here, we used "less than or equal to" , because she can score the maximum score of 100 % or less than 100 %
Combining both the inequalities we get,
All real numbers greater than or equal to 82% and less than or equal to 100%
Thus the required inequality is found
