let her lunch = l, her gym clothes = g, her books = x
20 pounds is the amount she can carry
her lunch (1) weighs 0.75 lbs
her clothes (1) weighs 2.3 lbs
her books (x) = 3.4 lbs
Set the inequality
3.4x + 2.3 + 0.75 ≤ 20
Simplify
3.4x + 3.05 ≤ 20
3.4x + 3.05 (-3.05) ≤ 20 (-3.05)
3.4x ≤ 16.95
3.4x/3.4 ≤ 16.95/3.4
x ≤ 4.99 (rounded)
x ≤ 4.99 can be one of your inequalities.
her books can weigh up to 4.99 pounds before her backpack breaks
hope this helps
Hey there!
Let's say that Julia has 50 CDs. We would plug this into c in the expression we've been given to find the number of CDs that Ahmed has.
c = 50
1/2c + 5
1/2(50) + 5
25 + 5
30
So, if Julia has 50 CDs, Ahmed has 30. We used the expression to figure that out and, therefore, that's why it was created.
Your answer will be the number of CDs that Ahmed has.
Hope this helped you out! :-)
