Nadya [2.5K]

Answer:

21

Step-by-step explanation:

Let x = $1 bill

Let y = $5bill

<em>Translating the word problem into an algebraic equation;</em>

<em>For the total number of bills;</em>

x + y = 47 .........equation 1

<em>For the total number of tips;</em>

x + 5y = 131 ..........equation 2

<em>*Solving the linear equation by using the substitution method*</em>

<em>Making x the subject in equation 1:</em>

x = 47 - y .......equation 3

<em>Substituting "x" into equation 2;</em>

(47 - y) + 5y = 131

<em>Simplifying the equation, we have;</em>

47 + 4y = 131

4y = 131 - 47

4y = 84

y = \frac {84}{4}

y = 21 (For the $5 bills).

<em>Therefore, Anthony received 21 pieces of the $5 bills.</em>

To find x;

Substituting "y" into equation 3;

x = 47 - 21

x = 26 (For the $1 bill).

Kazeer [188]

Answer: 59.5 minutes.


Step-by-step explanation:

1. You have the following information given in the problem above:

- 8 songs are 4.25 minutes long.

- 3 songs are twice as long as each of the others.

2. Therefore, the total time of 8 songs is:

(8)(4.25min)=34min

3. And the total time of the 3 songs is:

(2)(3)(4.25min)=25.5min

4. Therefore, you have that the result is:

34min+25.5min=59.5min

Answer:

Step-by-step explanation:

6 - 2x = 5x - 9x + 10  {add the like terms}

6 - 2x = - 4x + 10        {add (-6) to both side}

6 - 2x - 6 = - 4x + 10 - 6

-2x = - 4x + 4         {add 4x to both sides}

-2x + 4x = -4x + 4 + 4x

2x = 4           {divide both sides by 2}

2x/2x = 4/2

x = 2
