**Step-by-step explanation:**

**Answer:**

In mathematics, a ratio indicates how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six (that is, 8∶6, which is equivalent to the ratio 4∶3).

3 different ways you can write that ratio-

1) 4 to 3

greg drove 300 miles at a constant speed for 5 hours. the speed limit is 70 miles per hour. was his rate grater than the speed limit?

### Answers

**Answer:**

**No.**

**Step-by-step explanation:**

**To find the rate for how many miles Greg drove for 5 hours, we need to divide 300 by 5:**

**300 / 5 = 60.**

**60**** miles represents the speed for ****1**** hour.**

**60<70.**

**The inequality indicates that his rate (60 miles per hour) is ****less**** than the speed limit. **

**Answer:**

See below

**Step-by-step explanation:**

1)

x + 5 = 12, subtract 5 from both sides

x = 7

**Subtraction **property of equality

a = ba - c = b - c

2)

x + y = 20 and y = 5, substitute 5 into first equation

x + 5 = 20

**Substitution **property of equality

a + b = c and b = da + d = c

3)

2x - 3 = 11, interchange the sides of equality

11 = 2x - 3

**Symmetric **property of equality

a = bb = a

**Answer:**

1. if x + 5 = 12, then x = 7

:**Subtraction**** ****property**** ****of**** ****equality**

2. If x + y = 20, and y = 5, then x + 5 = 20.

2x − 4y = -4 , 3x + 2y = 22 solve the system by elimination.

### Answers

**Answer: 5, 7/2**

**Step-by-step explanation:**

2x − 4y = -4

3x + 2y = 22

divide both sides of the equation by 2

x − 2y = -2

3x + 2y = 22

Eliminate one variable by adding the equation; sum the equations vertically to eliminate at least one variable

4x=20

Divides both sides by 4

x=5

Substitute the given value of x into the equation 2x-4y = -4

2*5-4y =-4

solve the equation for y

A restaurant chain would like to measure the proportion of customers who are generally satisfied with the service provided by its staff. At the end of the meal, as the check is delivered to the table, the server asks those at the table to rate their satisfaction with the service provided as "Very Satisfied,” "Satisfied,” or "Not Satisfied.” During a one-week period, 147 customers were surveyed and 135 (93%) reported they were either Satisfied or Very Satisfied. How might the results be biased in obtaining an estimate of all customers who are satisfied with service?

Because of response bias, the survey results may overestimate the true proportion of satisfied customers.

Because of response bias, the survey results may underestimate the true proportion of satisfied customers.

Because of voluntary response bias, the survey results may overestimate the true proportion of satisfied customers.

### Answers

The **inequality** that best describes the possible **values** of **x** is; Choice A: **2 < x < 10**

In a **polygon** such as that given in the question;

Two scenarios may occur regarding angle; **(3x -6)**

They are as follows:

3x - 6 < 24. OR3x - 6 > 0.

This is so because angle **3x - 6** must be between **0°** and **24°** since **36 > 34**

By evaluation;

3x - 6 < 24

3x < 24 + 6

3x < 30

x < 30/3

x < 10

Also,

3x - 6 > 0

68 1/4

The **distance **travelled before their first gas stop is 68 1/4 miles given in mixed fractions.

What is a mixed fraction?

A **fraction **consisting of a quotient and remainder is a mixed fraction. we can convert the mixed fraction to improper fraction by first dividing the numerator by denominator and then taking the quotient as whole number and remainder as the numerator of **proper fraction **keeping the denominator same.

Assume the **distance** covered before their first stop for gas be 'x'

Total distance travelled is 381 miles

We are given that after stopping for gas they travelled 58 3/4 miles and then tripled their distance. The **equation **formed is

x + 3x + 58 3/4 = 381

4x + 58 3/4 = 381

48-12y+4y = 8

48-8y = 8

48-8 = 8y

-Equilateral

-Isosceles

-Scalene

-Acute

-Equiangular

-Obtuse

-Right

### Answers

**Answer:**

Scalene

Acute

Obtuse

**Step-by-step explanation:**

≠ Equailateral because all the sides in the given triangle are not equal nor are the three angles 60°

≠ Isosceles because the triangle doesn't have two equal sides nor two equal angles

= Scalene as all the sides are of different lengths and so are all the angles with different degrees.

= Actue because QPO and PQO are less than 90°, thus they are acute angles

≠ Equiangular because none of the given angles are of the same degree.

= Obtuse as POQ is greater than 90°

≠ Right because the given triangle does not have a right angle

**Step-by-step explanation:**

This means that 7x - 11 + 5x - 2 + 2x - 3 = 180.

**2. (Solving)**

**Step 1: **Combine like terms.

[tex](7x+5x+2x)+(-11-2-3)=180[/tex] [tex]14x -16 = 180[/tex]

**Step 2: **Add 16 to both sides.

**Step 3: **Divide both sides by 14.

A 6am one morning the temperature was -14 degrees by noon it rose 8 degrees and then rose another 2 degrees by 3pm. By 6pm the temperature had dropped 5 degrees. What was the temperature at 6pm

### Answers

**Answer:**

-9 degrees

**Step-by-step explanation:**

-14 + 8 = -6

-6 + 2 = -4

-4 - 5 = -9

The temperature at **6pm** dropped down to **5°**.

What is a mathematical function, equation and expression? **function** : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the** domain **of the function and the set Y is called the **codomain** of the function.**expression** : A mathematical expression is made up of terms **(constants** and** variables)** separated by mathematical operators.**equation** : A mathematical equation is used to** equate** two expressions.

Given is that at 6am one morning the temperature was **-14 degrees** by noon it rose **8 degrees** and then rose another **2 degrees** by 3pm. By 6pm the temperature had dropped **5 degrees**

We can write -

T{6 AM} = - 14°

T{12 PM} = 8°

**T{3 PM} **= (8 + 2)° = **10°**

**T{6 PM}** = 10° - 5° = **5°**

Therefore, the temperature at **6pm** dropped down to **5°**.

A group of friends wants to go to the amusem*nt park. They have $180.50 to spend on parking and admission. Parking is $19.50, and tickets cost $23 per person, including tax. Write and solve an equation which can be used to determine pp, the number of people who can go to the amusem*nt park.

equation:

answer p:

### Answers

a.

The **required equation** is **23p + 19.50 = 180.50**

Let **p **represent the** number of people **who can go to the **amusem*nt park.**

Since the ticket costs $23 per person, the total amount paid for ticket is **rate × number of person** = $23 × p = **23p.**

Since we pay $19.50 for parking, the total amount spent is **T = 23p + 19.50**

Since the total amount equals $180.50. T = 180.50

So, **23p + 19.50 = 180.50**

The **required equation** is **23p + 19.50 = 180.50**

b.

Solving ** 23p + 19.50 = 180.50**, we have

23p = 180.50 - 19.50

23p = 161

p = 161/23

**p = 7**

So, the **number of people** who can go to the** amusem*nt park **is **7.**
