Answer: 2:3
Step-by-step explanation:
The fraction 12/18 is equivalent to 2/3.
Let a = weight of large box in pounds
Let b = weight of small box in pounds
(1) 65a + 70b=4000
(2) a+b=60
Now we can simultaneously solve these equations.
a = 60 - b. Hence 65(60 - b) + 70b = 4000 So 3900 + 5b = 4000 and 100 = 5b hence b = 20.
SImilarly a = 40. Now we can verify too by putting in the calculated values.
The answer is
B) 2n - 5
because it's -5 than twice the width (2n)
Answer:
B
Step-by-step explanation:
This is one example of a trinomial with a leading coefficient of 3 and a constant term of -5
