The first inequality has solution
4p > -8 . . . . . . subtract 1
p > -2 . . . . . . . divide by 4
This is graphed as an open dot at -2, with shading to the right.
Neither inequality symbol includes "or equal to", so both dots are open dots. The appropriate choice is the first one:
a number line with open circles at negative 2 and 5 with shading in between
4n-9=15. N=6 (n stands for number)
1.) you would distribute the 6---- 12x-66+15
2.) you would add like terms---- 12x-51=3x+12
3.) you would subtract 3x from each side of the equal sign---- 9x-51=12
4.) you would add 51 on each side of the equal sign----9x=63
5.) you would divide both sides of the equal sign by 9 giving you you answer--------- x=7

Answer:
Solution given:
2x+10=28
subtracting both side by 10
2x+10-10=28-10
2x=18
dividing both side by 2
2x/2=18/2
x=9
