Answer: if you are going for the top it is 5 for 5e bottome it is 3 for all it is 3.5
Step-by-step explanation:
X= # students who got lower grades
2x+3= # students with grade A
STEP 1:
Add the two sets above equal to 24.
x + (2x + 3)= 24
combine like terms
3x + 3= 24
subtract 3 from both sides
3x= 21
divide both sides by 3
x= 7 (# students lower than A)
STEP 2:
substitute x value from step 1 to find # grade A students
=2x + 3
=2(7) + 3
=14 + 3
=17 (# grade A students)
CHECK:
x + (2x + 3)= 24
7 + 2(7) + 3= 24
7 + 14 + 3= 24
24= 24
ANSWER: There were 17 students with grade A.

Answer:
The missing value of x is 3
Step-by-step explanation:
Given Table:
x y
3 10
__ 20
The relation of x and y (x,y) is not a function.
Relation is function if it is one-to-one.
One-to-one means to different value of x to get different value of y.
If function is not a function then one value of x to get two different value of y.
For first value of x=3, y=10
For which value of x= ? , y=20
x must be 3
x=3 to get y=20
The missing value of x is 3 because same of x we get two different value of y.
