Blue triangle: perimeter is 4x+2+7x+7+5x-4, or, after simplification,
16x + 5
Red triangle: perim. is 2x-5+x+7+x+3 (and so on).
Answer:
x>24
Step-by-step explanation:
Solve like a normal equation :)
-2x<-48
Now we divide.
-x<-24
Note: Whenever dividing by a negative, you have to flip the sign of the inequality!
x>24
Answer:
just add 76+44=120
Step-by-step explanation:
78÷18=4.3333333
so it's 4.33333 many pancakes with one cup
so then you multiply 4.33333... by 12 which equals 52
So you can make 52 pancakes with 12 cups of flour
