Step-by-step explanation:
5×6'3n=20
30'3n=20
3n=20-30
3n/3= -10/3
n= -3
D. because for every hour it goes down 5 degrees and since there is a 1 hour gap in between 7 am and 9 am
It’s E because if your multiply 5 x 2x u get 10x and 10 x5 = 50 so our answer is E 10x +50
New length = 30x110% = 33cm
new width = 20x105% = 21cm
original perimeter = 30x2 + 20x2
= 60 + 40 = 100
new perimeter = 33x2 + 21x2
= 66 + 42 = 108
increase in perimeter = 108-100 = 8
percentage increase = 8/100 x 100% = 8%
