To solve this, write a proportion of Pounds to Cost:
Pounds: 3 x
Cost: 25.50 42.50
Cross multiply 3 and 42.50, this gives you 127.5
Then, divide by 25.5
This gives you 5.
You can buy 5 pounds with $42.50
24 divided by 6 plus 9 subtract 3 divide 2 =5
Answer:

Step-by-step explanation:
Hi!
Lets call:
T = temprature of the object
T₀ = temperature of surroundings
t = time
The rate of change of T is its derivative with respecto to time. If T > T₀, the object looses heat, so T decreases. Then, being k > 0:

In this case T₀ = 70ºF and k = 0.05/min. Then the differential equation is:

Answer:
degree of polynomial = 5
leading term = 
leading coefficient = 2
constant term = -6
Step-by-step explanation:

(i) The degree of the polynomial = 5. That is, the highest power of x
(ii) Leading term =
. This is the term with the highest power of x.
(iii) Leading Coefficient = 2. That is, the coefficient of the leading term (
)
(iv) Constant term = -6. This is the term that is independent of x or the term in which x doesn't appear.
