A house painting company charges $350 plus $15 per hour. Another company charges $275 plus $20 per hour. Write an equation that represents when both companies will cost the same amount. How long will the job be when both companies charge the same amount? How much will they charge?

Question 1: Write an equation.

Question 2: How long will the job be when both companies will cost the same amount?

Question 3: How much will they charge?

### Answers

**Answer:**

BelowI hope it helps ♥

**Step-by-step explanation:**

**1. Equation representing when both companies will cost the same amount :**

[tex]350 + 15x = 275 + 20x[/tex]

**2. Let x equal the number of hours a job takes , then the first house painting company will charge 350+15x , the second house painting will charge 275 +20x. If the two companies charge the same amount , we will have; **

[tex]350 +15x = 275+20x\\\\350 - 275 = 20x - 15x\\\\75 = 5x\\\\\frac{75}{5} = \frac{5x}{5} \\\\15 = x\\\\x = 15\:hours[/tex]

**3. For a job that takes 15 hours , the first company will cost ;**

[tex]350 + 15(15) = 575[/tex]

** For a job that takes 15 hours , the second company will cost ;**

### Answers

**Answer:**

slope is -2/5

y-intercept is 4

**Answer:**

See Below

**Step-by-step explanation:**

Ok, so slope intercept form is:

y = mx +b

Where m = slope and b = your y-intercept

lets line them up

y = mx + b

y =-2/5 x + 4

Notice that the m and b are lined up each corresponding #.

Therefore,

m = -2/5

B = 4

**Slope = -2/5**

**y - intercept = 4**

if each side of the cube shown above has the same length as the measured side what is the approximate volume of the cube

### Answers

**Answer:**

The measured side is not shown, so i will answer in a general way.

A cube is a 3-dimensional object with 6 square faces.

You know that all the sides of a square have the same length, then is the same for the cube.

To calculate the volume of a cube, we start with the area of the base.

The base is a square of sidelength L (Suppose that L is the length of the measured side)

The area of the base is:

A = L^2.

To find the volume, we must multiply the area of the base by the height of the fire (because the section of the base does not change).

And the height of the cube is also L.

Then the volume is:

V = L*a = L^3

Describe Maysa's error. Explain how you would use a model or place-value concepts to help Maysa build understanding. Give the correct answer in your explanation.

### Answers

The correct answer for the given **subtraction **is:

3.5 - 2.46 = 1.04

**How to solve the subtraction?**

Here we want to find the** subtraction **between two numbers in** decimal form:**

**3.5 - 2.46 = 1.16**

Now, this is clearly wrong, as 0.46 is smaller than 0.5, so the decimals after the decimal point are incorrect, now let's solve it again.

First, we can rewrite these two numbers as:

3.5 = 3 + 0.5

2.46 = 2 + 0.46

Then the **subtraction** can be rewritten as:

3.5 - 2.46

(3 + 0.5) - (2 + 0.46)

Now we group like terms:

(3 - 2) + (0.5 - 0.46)

1 + (0.50 - 0.46)

1 + (0.04)

Now we group that, so we get:

1 + (0.04) = 1.04

This is the correct answer to the given **subtraction**.

### Answers

**Answer: **[tex]m[/tex]** = −3**

**Step-by-step explanation:**

Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.

**Step 1:** *Expand.*

−40 − 6[tex]m[/tex] − 1 = 7[tex]m[/tex] − 2

**Step 2:** *Simplify −40 − 6*[tex]m[/tex]* − 1 to −6*[tex]m[/tex]* − 41.*

−6[tex]m[/tex] − 41 = 7[tex]m[/tex] − 2

**Step 3:**** ***Add 6*[tex]m[/tex]* to both sides.*

−41 = 7[tex]m[/tex] − 2 + 6[tex]m[/tex]

**Step 4:** *Simplify 7*[tex]m[/tex]* − 2 + 6*[tex]m[/tex]* to 13*[tex]m[/tex]* − 2.*

−41 = 13[tex]m[/tex] − 2

**Step 5:**** ***Add 2 to both sides*

−41 + 2 = 13[tex]m[/tex]

**Step 6:**** ***Simplify −41 + 2 to −39.*

−39 = 13[tex]m[/tex]

**Step 7:**** ***Divide both sides by 13.*

−[tex]\frac{39}{13}[/tex] = [tex]m[/tex]

**Step 8:**** ***Simplify *[tex]\frac{39}{13}[/tex]* to 3.*

−3 = m

**Step 9:**** ***Switch sides.*

[tex]m[/tex]** = −3**

Old Man Withers just died. He left his collection of baseball cards to his two sons. Bill got 55% of the collection and his brother Bob received the rest.

How many cards did Bill receive if Bob received

360 cards, then how many cards did Bill as inheritance from his father?

### Answers

**Answer:**

**Step-by-step explanation:**

Bill = 55% of the entire collection

Bob = 45% of the entire collection (Since we know 100 - 55 = 45)

We are also told that Bob received 360 cards.

This means that 45% = 360 cards.

First step is to find how many cards is 1%. To do this, divide 360 by 45.

1% of entire collection = [tex]\frac{360}{45} = 8[/tex] cards

This means that since Bill gets 55% of the entire collection, you multiply 8 by 55.

Bill = 8 x 55 = 440 cards.

**Answer:**

440
