Perimeter is all sides added up.
Area is sometimes length times width with four sided figures like a rectangle or a square and for like triangles it is base times height.
The answer is going to be 14 15 16
14+15+16 = 45
First step
5.(2x-8)
= (5.2x) + (5. (-8) )
=10x + (-45)
note :(+) . (-) = (-)
so + (-45)= (-45)
Add 15 to this equation
= 10x -40 +15= -15
=10x -25= -15
Leave x alone and make it positive
By the way, if you put (-25) in the right term, this number's notation (I mean -) will change
Namely
= 10x= (-15)+25
=10x= 10
x=1
Hope it helps :)
P.s. I dont know mathematical terms that's why i couldn't explain it properly but i tried to help as far as i can :)
Answer:
Step-by-step explanation:
So first we combine like terms on the left
1-7=-6
then we have
-7x-6=15
next we add 6 both sides
-7x-6=15
+6 +6
-7x=21
then we divide -7 each side
we get
x=-3
Okay so what you would do is 1.5 multiply by 3 find out the answer there and then subtract the 5 cups with the answer.
so if it is 1.5×3 that would equal ____ then you would subract 5 - ___ then there is your answer
