8< =4+2p<=20
where p is the pounds of jelly beans
subtract 4 from all sides
4 <= 2p <= 16
divide by 2
2<= p <= 8
5. y = x + 7
6. y = -x + 1
Think of sea level as 0 on number line
-13 + 6 - 15
Answer:
x = 12
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the opposite interior angles
10x-10 = 60 +4x+2
Combine like terms
10x-10 = 62+4x
Subtract 4x from each side
10x-4x -10 = 62 +4x-4x
6x -10 = 62
Add 10 to each side
6x-10+10 = 62+10
6x= 72
Divide by 6
6x/6 = 72/6
x = 12
