Homer Simpson weighs 400 pounds. He is on a diet to lose 5 pounds each week Barney weighs 322 pounds. he is on a diet to lose 3 pounds each week. How long will it take for them to weigh the same? write an equation and solve.

Answers

400 + (n-1) (-5) = 322 + (n-1) (-3)
-5n + 5 = 322 
-3n + 3    | 405 - 5n
               =325 - 3n
80=2n
n=40            n - 1 = 39    

 Answer = 39 , 39 weeks until they weigh the same

Given p(x)=3x^5+2x^2-5, what is the value of the function at -5/3

Answers

Answer:

-(3080)/(81)

Step-by-step explanation:

The given function is:

p(x)=3x^(5)+2x^(2)-5

We have to find the value of the function at x = -5/3

In order to do this we need to replace every occurrence of x in the given function by -5/3. i.e.

p(-(5)/(3))=3(-(5)/(3))^(5)+2(-(5)/(3) )^(2)-5\n\n p(-(5)/(3))=3(-(3125)/(243) )+2((25)/(9) )-5\n\np(-(5)/(3))=-(3125)/(81)+(50)/(9)-5\n\n p(-(5)/(3))=-(3080)/(81)

Thus, the value of the function at x =-5/3 is -(3080)/(81)

Farid takes 7/8 teaspoon of allergy medicine every day. How much medicine will he take in one week?

Answers

If Farid takes (7)/(8) teaspoon of allergy medicine every day, he will take 6 and (1)/(8) teaspoons of allergy medicine a week. This problem is based on the principle of multiplication.

The principle of multiplication states that when two or more numbers are multiplied by each other, a new number is obtained, called their product.

Some of the examples are 2 × 6 =10; 3 × 5 × 10 = 150; 6 × 1 × 3 = 18, etc. 1 is the multiplicative identity as any number multiplied by 1 remains the same, e.g., 6 × 1 = 6.

Given that

The number of teaspoons of allergy medicine Farid takes every day = (7)/(8) .

The number of days in a week = 7.

The number of teaspoons of allergy medicine Farid takes in a week  =(7)/(8)* 7

=(49)/(8) \n=6(1)/(8)\n=6+(1)/(8).

Thus, Farid takes 6 and (1)/(8)teaspoons of allergy medicine a week.

#SPJ6
he takes 7/8 per day and there are 7 days in a week
so multiply 7/8 by 7/1 since 7 divided by 1 is still 7.
(7/8) x (7/1)
then multiply the top numbers for numerator and bottom for denominator
7    x     7                           49
                        you get
8     x     1                           8

if you need to go further you divide the 49 by 8 and get 6.125. 
6.125 = 6 and 1/8
6 is the whole number and .125 out of 100 equals 8
