Answer:
12 teachers will get 1/2 sheets each
Step-by-step explanation:
Noor bought 21 sheets of stickers
She gave 1/3 sheets to each 45 students
She wants to give teachers 1/2 of sheets
The question should be: how many teachers will she give
Total sheets=21
Students gets= 1/3 × 45
=45/3
=15 sheets
Remaining sheet= total sheets - students sheets
=21-15
=6 sheets
There are 6 sheets remaining for teachers
She wants to give 1/2 to each teacher
Then,
The number of teachers that will get =Remaining sheets ÷ each teacher's share
=6 ÷1/2
=6 × 2/1
=12 teachers
12 teachers will get 1/2 sheets each

Not a proper question. But I think it's a 5
Answer:
Step-by-step explanation:
Hello,
Pls post the full question next time so that we can make sure what is expected.
I assume that you want to solve for (x,y)
(1) 2x + 3y = 7
(2) 3x + 2y = 8
2*(2)-3*(1) gives
2*3x + 2*2y - 3*2x - 3*3y = 2*8 - 3*7 = 16 - 21 = -5
6x - 6x + 4y -9y = -5
-5y=-5
y = 1
and we can replace in (1)
2x + 3*1 = 7
2x = 7 - 3 = 4
x = 2
hope this helps
Option B:
Solution:
Given expression:
To find the value of x:
Convert mixed fraction into improper fraction.
Divide by 3 on both sides of the equation, we get
Taking square root on both side of the equation.
Convert improper fraction into mixed fraction.
Hence option B is the correct answer.
X over .82 = 8 over 100
cross multiply .82 by 8
.82×8=6.56
divide 6.56 by 100.
6.56÷100=.0656
round to 7
.07
add .82 to .07.
.82+.07= .89
the candy bar cost $0.89
Hope this helped. : )
