From what i see, i guess the answer may be B. it looks like it, but i dont really know.
14 is the answer to number 10
Answer:
The correct options for the solution values are:
Step-by-step explanation:
Given the expression

Subtract 25 from both sides

Simplify

Add 25 or 5² to both sides

as

so the expression becomes


solve

Subtract 5 from both sides


solve

Subtract 5 from both sides


Therefore, the solution to the equation

Hence, the correct options for the solution values are:
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.
Hope this helps! :)
