Triple 4 is just 12
4X3=12
And so you can then divide by 2 because 2 each day(you could also just keep subtracting). Either way, you get 6 days
Answer:
4) 7
5) -12
Step-by-step explanation:
4) 5x+2= 37
5x= 37-2
x= 35/5
x= 7
5) -6x-7= 65
-6x= 65+7
x= 72/-6
x= -12
A=lw, right? So you would take what you know, 323 being a and 19 being l. 323=19w
Divide both sides by 19 leaving you with
323/19=w
17 feet=w
Answer:
