Answer: 16 miles


Explanation:
I believe it would be 16 miles, if he starts off at 6 miles on day one and goes up 1/2 mile every day, he would be up a mile every other day, basically on day 3 he would be at 7 and day 5 at 8 miles, if the pattern continues he would be at 16 miles by day 21.

Please help! 3 Questions please show how you solved the problem
Masteriza [31]

Answer:

1)  (-y^2-4y-8+4y^2+6y-3)

2)  32x^5y^4z^2

3)  x^3-9x^2+14x+24

Step-by-step explanation:

Given the expression we have to simplify the expression

1)   (-y^2-4y-8)-(-4y^2-6y+3)

⇒ (-y^2-4y-8+4y^2+6y-3)

Combining like terms, we get

⇒ 3y^2+2y-11

2.)    (2x^2y^3z^2)(4xy.4x^2)

⇒ (2x^2y^3z^2)(16x^3y)

⇒ 32x^5y^4z^2

3.)   (x-4)(x^2-5x-6)

⇒ x^3-5x^2-6x-4x^2+20x+24

⇒ x^3-9x^2+14x+24

The average of a list of 4 numbers is 90.0. A new list of 4 numbers has the same first 3 numbers as the original list, but the f
Thepotemich [5.8K]

Answer:

the average of this new list of numbers is 94

Step-by-step explanation:

Hello!

To answer this question we will assign a letter to each number for the first list and the second list of numbers, remembering that the last number of the first list is 80 and the last number of the second list is 96

for the first list

\frac{a+b+c+80}{4} =90

for the new list

\frac{a+b+c+96}{4} =X

To solve this problem consider the following

1.X is the average value of the second list

2. We will assign a Y value to the sum of the numbers a, b, c.

a + b + c = Y to create two new equations

for the first list

\frac{y+80}{4} =90

solving  for Y

Y=(90)(4)-80=280

Y=280=a+b+c

for the second list

\frac{y+96}{4} =X\\

\frac{280+96}{4} =X\\x=94

the average of this new list of numbers is 94
