If u just give me my fricking points its 91
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! :)
Answer:
M has 41 CDs
Step-by-step explanation:
Joel = 2 x M
(Joel -7) / 3 = Black
Black = 25
Joel - 7 = 3 x Black = 3 X 25 = 75
Joel = 75 + 7 = 82
M = 82 / 2 = 41
