Answer:
1) either 5 or 6 students in the group
2) 6 rooms are booked
Step-by-step explanation:
1) x students
3x + 8 = apples
5 (x-1) + y (the one get less than 5 apples)
3x + 8 = 5 (x - 1) + y
3x + 8 = 5x - 5 + y
2x + y = 13
X 1 2 3 4 5 6
Y 11 9 7 5 3 1
because y < 5 so x = 5 or x = 6
2) x rooms are booked
4x + 20 total students
8 (x-1) + y (the students in room not full))
4x + 20 = 8 (x-1) + y
4x + 20 = 8x - 8 + y
4x + y = 28
X 1 2 3 4 5 6
Y 24 20 16 12 8 4
y < 8 answer is 6 rooms
5+(-7)+3+(-6)=-5

Step-by-step explanation:
right.
and therefore c is in this case the name of the variable in the equation (or function).
add on.
ah, do you mean (and does this strange problem description mean) that you want the reverse formula : to get C out of F ?
in that case
F = 1.8c + 32 = 9/5 × c + 32
F - 32 = 9/5 × c
5/9 × (F - 32) = c
or
c = 5/9 × (F - 32)
that's it.
