Answer:
the weight of 1 textbook is 2 pounds
the weight of 1 game is about 0.5 pounds
Step-by-step explanation:
1/2 of 2 = 0.5 pounds
0.5 times 8 (games) = 4
22 - 4 = 18
18 divided by 9 (textbooks) = 2 pounds
Answer:
Each game is 0.5 pounds and each textbook is 2 pounds.
Step-by-step explanation:
If x represents games and y represents textbooks you can use the equation
6x + 9y = 21
we know that if the box was 21 pounds and she adds two games and it's now 22 pounds that each game is 0.5 pounds so x = 0.5
after plugging in the x value the equation is:
3 + 9y = 21
Combine like terms and it's 9y = 18
Divide 18 by 9 and you get:
Y= 2
Hope this helps! Good luck on your test.
