To make 100mL of 5M solution, you could dilute 10mL of the 5M solution with 90mL of solvent (usually water) to achieve the desired volume. This would retain the 5M concentration while reducing the volume to 100mL.
-5m-3+4 = 11 -5m = 11+3-4 -5m = 10 m = -2
-3m = 5m+8 -3m-5m = 8 -8m = 8 m = -1
5 x 0.5 = 2.5 meters^2
m = 4
8m*5m=40 m2 The area of the rectangle is 40m2
5m = 2m - 153m = -15m = -15/3m = -5
m = -1
