Hi sorry for the late response, I know the assignment was due at 5pm today but anyway here is the answer.

System:

<em>d= 5(0.75-t)</em>

<em>d= 20t</em>

<em>20t = 3.75 -5t</em>

Define Variables:

<em>d = how far Carol Skied</em>

<em>t = time it took Carol to go up/down</em>

Solve:

20t = 3.75 -5t

20t + 5t = 3.75 -5t + 5t            

25t = 3.75

25t/25 = 3.75/25

t = 0.15

<u><em>Now we plug in the time into the Distances:</em></u>

20t = 3.75 - 5t

20(0.15) = 3.75 - 5(0.15)

3 = 3.75 - 0.75

3 = 3

Solution as Sentence:

<u><em>Carol Skied 3 miles</em></u>

<u><em /></u>

PLEASE HELP Use the expression 9(7 + 2 times x) to answer the following: Part A: Describe the two factors in this expression. (4
White raven [17]
Part A:
The two factors of this expression are 9 and 7+2x. The first factor is a constant consisting of only one element. The second factor is a binomial which means it is consisted of two elements or terms.

Part B:
As already described above, the first factor only has 1 term and the second, being a binomial, has two terms. 

Part C:
The term which is linked to the variable is 2x. This means that the numerical coefficient of the variable term is 2. 

Moreover if we try to simplify the factors by distribution, we get,
   63 + 18x
This will then tell us that the coefficient of the variable term is 18.

Find the value of x in the equation below. 2x+8/6=1/3(x+4) A. x = 0 B. no real solutions C. infinitely many solutions D. x = 1
USPshnik [31]

Answer:

x = 0

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

2*x+8/6-(1/3*(x+4))=0

Simplify 1/3

Equation at the end of step  1 :

(2x +  8/6) -  (1/3 * (x + 4))  = 0  

STEP  2 :

Equation at the end of step 2

 (2x + 8/6) -  (x+4)/3  = 0  

STEP  3 :  

Simplify 4/3

Equation at the end of step  3 :

(2x + 4/3) -  (x+4)/3  = 0  

STEP  4 :

Rewriting the whole as an Equivalent Fraction

Adding a fraction to a whole

Rewrite the whole as a fraction using  3  as the denominator :

2x =  2x/1  =  2x*3/3

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

2x * 3 + 4/3  =  6x+4/3

Equation at the end of step  4 :

(6x+4)/3 -  (x+4)/3  = 0  

STEP  5 :  Pulling out like terms

Pull out like factors :

6x + 4  =   2*(3x + 2)  

Adding fractions which have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

2*(3x+2)-((x+4))/3  =  5x/3

Equation at the end of step  5 :

5x/3 = 0  

STEP  6:  When a fraction equals zero

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now, to get rid of the denominator, multiply both sides of the equation by the denominator.

Here's how:

5x/3*3 = 0*3

Now, on the left hand side, the 3 cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

5x  = 0

Solving a Single Variable Equation:

Solve  :    5x = 0  

Divide both sides of the equation by 5:

x = 0
