Step-by-step explanation:

First, you come up with an equation based on the problem:

3x+x=20

Then you simplify:

4x=20

Now you divide 20 by 4 to get the answer 5 FOR X

Still you have to find out the strawberry arrangements

Since it is three times, multiply 5 and 3 to get 15

Step-by-step explanation:

Question... isn't it just the real number?

The first table represents y as a function of x.

If a table represents a function, each of the x-values will have only one possible y-value that corresponds to it, however, two different x-values can have the same y-value.

All the tables, except the first table, have x-values that have more than one y-value assigned to it.

The first table have exactly one y-value that corresponds to each of the x-values. Therefore, the first table represents y as a function of x.

Step-by-step explanation:

The length of LN in units is 64 units

The complete question is added as an attachment

From the question, we have the following parameters

LM = 10x + 8

MN = 5x - 4

LN = 12x + 6

The above means that

LN = LM + MN

So, we have

10x + 8 + 5x -4 = 12x + 16

Evaluate the like terms

So, we have

15x +4 = 12x + 16

Collect the like terms

So, we have

15x - 12x = 16 - 4

Evaluate the like terms

So, we have

3x = 12

Divide both sides by 3

x = 4

Next, we substitute x into LN = 12x + 16

So, we have

LN = 12(4) + 16

Evaluate

LN = 64

Hence, the length of LN in units is 64 units

The graphs for which we choose the one which is not a function are missing, and are given at the end of the answer.

A graph represents a function if it has no vertically aligned points, that is, each value of x is mapped to only one value of y. Vertically aligned points mean that a value of x is mapped to multiple values of y, that is, a single input is mapped to multiple outputs which disqualify the relation as a function.

The number is 5.

Eight more than six times a number is the same as two less than 8 times the number.

Let

the number  = x

Therefore,

8 + 6x = 8x - 2

add 2 to both sides of the equation

8 + 6x = 8x - 2

8 + 2 + 6x = 8x - 2 + 2

10 + 6x = 8x

subtract 6x from both sides of the equation

10 + 6x = 8x

10 + 6x - 6x = 8x - 6x

10 = 2x

divide both sides by 2

x = 10 / 2

x = 5

If  activity fee for an arts camp is $250. If the activity fee increases by 20% then $300 will be the new activity fee.

Percentage is a relative value indicating hundredth parts of any quantity.

Given activity fee for an arts camp is $250.

The activity fee increases by 20%.

We need to convert percent to decimal.

20%=20/100=0.2

We need to find what is 20% of $250.

So 0.2*250=50

So 50 is 20% of 250.

As activity fee increases by 20%  the new fee will be

$250+$50=$300.

Therefore $300 will be the new activity fee.

Answer:

Admin. tickets: 131

Teacher tickets: 218

Step-by-step explanation:

Let t = the number of teacher tickets

Let a = the number of admin tickets

t + a = 349

.6t + .9a = 248.70  teacher pay 60 cents and admin pays 90 cents.

Solve the first equations for t

t + a = 349

t = 349 -a  Substitute 349 - a for t into the second equation

.6(349 -a) + .9a = 248.70  I want to clear the decimal, so I will multiply through by 10

6 (349 - a) + 9a = 2487  Distribute the 6

6(349) - 6a + 9a = 2487

2094 - 6a + 9a = 2487  Combine like terms

2094 + 3a = 2487  Subtract 2094 from both sides

3a = 393  Divide both sides by 3

a = 131  This is the number of admin tickets purchases.

Plug 131 for a into either of the first two equations

t + a = 349

t + 131 = 349  Subtract 131 from both sides of the equations

t = 218

The purchase for teachers $130.8 and for administrators $117.9.

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:

let the number of teacher be x.

So, for Teacher after discount raffle tickets will be 0.60x

and, for administrators after discount raffle tickets will be 0.90(349-x)

Now, Total spent on raffle tickets=$248.70

248.70 = 314.1 - 0.9x + 0.6x

Answer:

he waters level dropped inch each hour

Step-by-step explanation:

- Between 10 P.M. and 7:45 A.M., the water level in a swimming pool

 decreased by 13/16 inch

- Assuming that the water level decreased at a  constant rate

- We need to find the drop each hour that means the unit rate of

 decreased of the level of the water

- At first lets hind how many hours between 10 P.M. and 7:45 A.M.

∵ Between 10 P.M. and mid-night 2 hours

∵ Between mid-night and 7:45 A.M. 7 hours and 45 minutes

- Lets change 7 hours and 45 minutes to hours

∵ 1 hour = 60 minutes

∴ 45 minutes = 45 ÷ 60 =  hours

∴ 7 hours and 45 minutes =  hours

∴ The total hours between 10 P.M. and 7:45 A.M. = 2 +  hours

∴ The total hours between 10 P.M. and 7:45 A.M. =

∵ The unit rate of decreased = The decreased level ÷ total hours

∵ The decreased level is  inche

∵ The total hours =  hours

- Lets change the mixed number  to improper fraction

∵  =

∴  =

∵ The unit rate of decreased =   ÷  

- To solve the division of 2 fractions change the division sign to

The Venn diagram shown to IV, V, VI, VII regions are represent set C.

It is given that the wind diagram we need to find the regions represent the set.

See from the diagram it shows that the regions IV, V, VI, VII represent us, etc.

A Venn diagram is an illustration that uses circles to show the relationships among things or finite groups of things. Circles that overlap have a commonality while circles that do not overlap do not share those traits. Venn diagrams help to visually represent the similarities and differences between two concepts.

So from the Venn diagram, the set C represents the regions four, five, six and seven.

Therefore, she can be written us for Union Fight, Union Six, Union Seven. Therefore, we concluded that the regions represent see R. C.

Which is equal to for Union Fighting Union Six, Union Seven.

We have here, region represent C

C ⇒ Union from C

The depth of the Japan Trench is 9 kilometers. There are 8 km below sea level in the Peru-Chile Trench. The difference of depth between them is 1km.

1. −17 km, and the Japan Trench is deeper is False.

2. −1 km, and the Peru-Chile Trench is deeper is False.

3. 1 km, and the Japan Trench is deeper is True.

4. 17 km, and the Peru-Chile Trench is deeper is False.

Given that,

The depth of the Japan Trench is 9 kilometers. There are 8 km below sea level in the Peru-Chile Trench.

Based on the difference in depth between the Japan Trench and the Peru-Chile Trench, which is 1 km deeper, the Japan Trench is deeper.

The trench that is lower to sea level has a deeper depth. In other words, it is the one that is lower than the others by a wider amount.

The depth of the Japan Trench is 9 kilometers. There are 8 km below sea level in the Peru-Chile Trench. The Japan Trench is hence deeper as a result.

The difference is 9-8=1 km
