The given weight of Joshua's math textbook = 4.21 ounce
The given weight of Joshua's social studies textbook = 3.99 ounce
Hence, the difference in weight between the both the textbooks is- subtract the weight of social studies textbook from math textbook, which is:
4.21 - 3.99 = 0.22 ounce
Hence the difference in weights is 0.22 ounce.
3.6m − 2.7 = −1.8m
Subtract 3.6m from both sides:
-2.7 = -5.4m
Divide both sides by -5.4:
m = -2.7 / -5.4
m = 0.5
Answer:
0.87
Step-by-step explanation:
0.8/4=0.2
0.7-0.81=-0.11
3*-0.11=-0.33
1.2+-0.33=0.87
