is your teacher trying to give you a stroke???
Step-by-step explanation:
<span>6-t/2t+9 = -2
multiply both sides by 2t+9
which will give you
6-t= -2(2t+9)
6-t = -4t + 18
now add 4t to both sides
6 -t + 4t = -4t -18 + 4t
6 + 3t = -18
6-6 + 3t = -18 -6
3t = -24
t = -24/3
t= -8 (negative 8)

Answer:
x = 8
Step-by-step explanation:
log(5x-4)-log(x+1)=log 4
log [ (5x - 4) / (x+ 1) ] = log 4
[ log (a/b) = loga - logb]
(5x - 4 ) / ( x + 1) = 4
(5x - 4) = 4x + 4
5x - 4x = 4 + 4
x = 8
Hope it will help :)❤
Answer: 7.71%
Step-by-step explanation:
Number of students in a school last year = 700
Number of students in a school this year = 646
Reduction in the number of students = 700 - 646 = 54
The percentage reduction will be:
= Reduction in number / Last year students × 100
= (54 / 700) × 100
= 7.71%
