Answer:
17. xy + z = 51
18 yz - x = 18
21. 5z + ( y - x ) = 20
22. 5x - ( y2 - 4x ) = -10
23 . x2 + y2 - 10z = 70
24. z3 + ( y2 - 4x ) = 1
25. y + xz / 2
26 .3y + x2 / z = 30

Answer: division , addition, addition, multiplication, subtraction, addition, multiplication
Step-by-step explanation: idrk know how to explain other than the fact that you look at the symbols.
The correct answer is option D.It is the graph that represents two quantities in a proportional relationship.
<h3>What is a graph?</h3>
A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
As we can see graph D is showing the correct proportionality. We can also create an equation of proportionality as:-
Y = 2x
Put y = 0.5
0.5 = 2 x 0.5 = 1
As we put y=0.5 we get the value of x = 1 as shown in the graph.
Therefore the correct answer is option D.It is the graph that represents two quantities in a proportional relationship.

Answer:
Step-by-step explanation:
Given: There are 2 classes of 25 students.
13 play basketball
11 play baseball.
4 play neither of sports.
Lets assume basketball as "a" and baseball as "b".
We know, probablity dependent formula; P(a∪b)= P(a)+P(b)-p(a∩b)
As given total number of student is 25
Now, subtituting the values in the formula.
⇒P(a∪b)= 
taking LCD as 25 to solve.
⇒P(a∪b)= 
∴ P(a∪b)=
Hence, the probability that a student chosen randomly from the class plays both basketball and baseball is .
