11-19m=-16m-16
move -16m to the other side
sign changes from -16m to +16m
11-19m+16m =-16m+16m-16 ( combine like terms)
11-19m+16m=-16
11-3m=-16
move 11 to the other side
sign changes from +11 to -11
11-11-3m=-16-11
-3m=-16-11
-3m=-27
divide both sides by -3 to get +m and by itself
-3m/-3=-27/-3
m=9
Check solution by using substitution method
11-19(9)=-16(9)-16
11-171=-144-16
-160=-160
Answer:
a) 1/2 of 12 = 1/4 of 24
b) 1/3 of 90 = 2/3 of 45
Step-by-step explanation:
1/2 of 16 is 6, so 6 would be 1/4 of what? 6 x 4 = 24. 6 is 1/4 of 24. The other one is the same. 1/3 of 90 is 30, and 30 is 2/3 of 45.
