**Answer:**

12.5 hours

**Step-by-step explanation:**

[tex]115 - 15 = 100 \\ \frac{100}{8} = 12.5[/tex]

The student **worked** for 12.5 **hours**.

A branch of mathematics known as **algebra** deals with **symbols **and the mathematical **operations **performed on them.

Variables are the name given to these symbols because they lack set values.

In order to **determine **the **values**, these **symbols **are also **subjected **to various addition, subtraction, multiplication, and division **arithmetic operations**.

Given:

A student **earns **$8 per **hour **plus a $15 **bonus **each weekend day worked.

Now, let the **student works **for h **hours**.

So, the **earning **would be= 15+ 8h

As, he **earned **$115

So, 15+ 8h= 115

8h = 100

h = 12.5 **hours**

Hence, the student **worked** for 12.5 **hours**.

**Answer:**

-259

**Step-by-step explanation:**

Subtracting a negative number is the same as adding a positive number — that is, go up on the number line. This rule works regardless of whether you start with a positive number or a negative number.

When subtracting a negative number, remember that the two back-to-back minus signs cancel each other out, leaving you with a plus sign.

Subtracting Negative and Positive Integers

To subtract integers, change the sign on the integer that is to be subtracted.

If both signs are positive, the answer will be positive.

Example: 14 - (-6) = 14 + 6 = 20

If both signs are negative, the answer will be negative.

Example: -14 - (+6) = -14 - 6 = -20

If the signs are different subtract the smaller absolute value from the larger absolute value. The sign will be the sign of the integer that produced the larger absolute value.

Example: 14 - (+6) = 14 - 6 = 8

Example: -14 - (-6) = -14 + 6 = -8

loria has some dimes and quarters. If she has 18 coins worth a total of $2.25, how many of each type of coin does she have?

**Answer:**

dimes: 5

quarters:8

**Step-by-step explanation:**

she has 2$ in quarters and $0.25 in dimes

**Answer:**

10 Dimes and 5 Quarter

**Step-by-step explanation:**

**Important info:**

18 Coins worth a total of $2.25

**Note:**

Dimes = .10

Quarter = .25

10 Dimes = 1.00

4 Quarter = 1.00

**Question to Answer:**

How many each type of Coin does she have?

**Solution:**

Lets get rid of .25 in $2.25 :)

So that **1 Quarter..**

2.00

Takes away 1.00 = 10 Dimes

Now we have **1 Quarter and 10 Dimes.**

1.00 Left..

4 Quarter = 1.00

So now we have **5 Quarter and 10 Dimes..**

**Check Work:**

5 Quarter = 1.25 and 10 Dimes = 1.00

1.25+1.00=

$2.25

Hence. Loria has 5 Quarter and 10 Dimes.

{ Couldn't figure out 18 Coins worth a total of $2.25 the closest I could get was 15 Coins worth a total of $2.25}

**Step-by-step explanation:**

I'm guessing at this a bit.

The final score will depend on what is par for each hole and/or for the entire course. The scores for the first four rounds were all negative. That means Ko required fewer strokes to hit the hole than the number considered "par" for the course.

Let P stand for the Par of the course. Then the score for each round would be:

P-3

P-4

P-7, and

P-2

The sum: 4P - 16 is her score for the first four rounds. I have no clue if there are more than 4 rounds, but if there are, the equation would be:

For n rounds:

nP - ∑[tex]x_{n}[/tex]

where ∑[tex]x_{n}[/tex] is the sum of over/under pars for the n rounds.

There are 120 people in a school canteen.

Half of the people in the canteen are in year 11 students.

The number of year 11 students in the canteen is three times the number of year 10 students.

The rest of the people in the canteen are year 9 students.

the number of year 9 students : the number of year 10 students = n : 1

Work out the value of n.

You must show how you get your answer.

2:1

**Step-by-step explanation:**

List all variables

Total people=120

year 11 students=120/2=60

year 10 students=60/3=20

subtract year 10 and 11 students from the total to get the number of year 9 students

year 9 students=120-60-20

=40

year9:year10

40:20

2:1

**Value** of **variable 'n'** as per the given condition **number** of 9 year students : **number** of 10 year students = n:1 is equals to **2**.

" A **variable** is defined as the quantity which represents the change in **value** as per the given condition in a mathematical problem."

According to the question,

Total** number** of students in school = 120

As per the conditions given we have,

**Number** of 11 year students = [tex]\frac{120}{2}[/tex]

= 60 people

**Number** of 11year students = 3 × ( **Number** of 10 year students)

⇒**Number** of 10 year students = [tex]\frac{Number of 11 year students}{3}[/tex]

= [tex]\frac{60}{3}[/tex]

= 20 people

**Number** of (11year + 10year + 9year ) students = 120

⇒ 60 + 20 + **Number** of 9 year students =120

⇒**Number** of 9 year students = 120 - 80

= 40 people

Substitute the **value** in the given condition to get the **value** of the **variable** we get,

**Number** of 9 year students : **Number** of 10 year students = n:1

⇒40 : 20 = n: 1

⇒**n = 2**

Hence, **value** of **variable 'n'** as per the given condition **number** of 9 year students : **number** of 10 year students = n:1 is equals to **2**.

How can I use the scale factor to determine if a picture is an enlargement?

**Answer:**

You can use the scale factor to determine if a picture is an enlargement if the scale factor is greater than 1. If it is less than 1 like 0.9 then the picture would be a reduction because you would be multiplying the number by a number smaller than 1. Now if we have a scale factor greater than 1 let's say 3. Then the picture would be an enlargement because the number is greater than 1.
