Answer:

x = 3y

x + y = 24

The number of social media advertisement purchased is 18

And, the number of newspaper advertisements purchased is 6

Step-by-step explanation:

Let us assume the number of social media advertisement purchased be x

And, the number of newspaper advertisements purchased be y

As three social media advertisements for every one newspaper advertisement is purchased

So,

y = x ÷ 3

x = 3y

And it is ended by total of 24 advertisement

That means

x + y = 24 ............(1)

Now put the value of x in equation 1

3y + y = 24

4y = 24

y = 24 ÷ 4

= 6

x = 3y

= 6 × 3

= 18

Now  The equations are

x = 3y

x + y = 24

Answer:

the last one because when using the distributive property,  you get

4x + 12 - 2x - 10

Answer:

4x + 12 + 2x + 10

Step-by-step explanation:

4( x + 3 ) -2( -x -5 )

1. Multiply 4 and x = 4x

2. Multiply 4 and 3 = 12

3. Multiply -2 and -x = 2x

(turns positive as there are 2 negative signs)

4. Multiply -2 and -5 = 10

(turns positive as there are 2 negative signs)

Answer:

the answers would be 12/35

because you all the animals together including the wolf and bobcat which is 35. so then you add the wolf and bobcat separately which is 12

Answer:

Step-by-step explanation:

Given that,

Point 1 = (-6,9)

Point 2 = (2,9)

To find,

The slope of a line that passes through the given pair.

Solution,

We have,

x₁ = -6, x₂ = 2, y₁ = 9, y₂ = 9.

The formula for the slope of a line is given by :

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}\\\\=\dfrac{9-9}{2-(-6)}\\\\=0[/tex]

Hence, the slope of the line that passes through the given pair is 0.

Step-by-step explanation: To divide mixed numbers, first rewrite the mixed numbers as improper fractions.

So here, 3/5 is already a fraction and 2 and 1/2 can be written as 5/2.

Remember that dividing by a fractions means the same thing

as multiplying by the reciprocal of that fraction.

In other words, 3/5 ÷ 5/2 can be rewritten as 3/5 · 2/5.

Finally, multiplying across the numerators and the

denominators, we have 6/25.

The result of the division of 3/5 divided by 2 1/2 is: 6/25.

Here, we have,

given that,

3/5 divided by 2 1/2

4 is the quotient of 100 divided by 25.

Here, we have,

given that,

100 divided by 25

now, we have to find the quotient of 100 divided by 25.

so, we get,

100 ÷  25

now, using the rule of division,

so, we get,

100/25

=> 20/5

=> 4/1

=> 4

Hence, 4 is the quotient of 100 divided by 25.

Answer: D

Step-by-step explanation:

Answer:

$15.90

Step-by-step explanation:

6% → 0.06

15* 0.06 = 0.9

15+0.9= $15.90

The equation contains variables on both sides equals 18 can be written as (2x - 18) = x.

A linear equation would be a type of equation with each variable's degree is completely identical to one.

Now, for the given question, the equation which could be represented in the form of variable on both side and has the solution equals to zero is;

(2x - 18) = x

The solution can be obtained as;

2x - 18 = x

Bring variable part on one side and constant on other.

2x - x = 18

x = 18.

Therefore, the equation with variables on both side the equals 18 is obtained as  (2x - 18) = x.

Answer:

Y=2.65x+2.50

Step-by-step explanation:

Given that:

Initial charge = $2.50

Charge per mile = $2.65

Find the total cost (y) of the trip ; if number of miles = x

Total cost of trip = initial charge + (charge per mile * number of miles)

y = $2.50 + ($2.65 * x)

y = $2.50 + $2.65x

Answer:

He bought 3 jumbo packs and 4 hobby packs.

Step-by-step explanation:

Ethan bought 4 number of hobby packs and 3 number of jumbo packs.

Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.

Linear equations may include one or more variables.

Let x be the number of hobby pack that Ethan buy and y be the number of jumbo packs that Ethan buy.

Ethan bought 7 packs for a total of 141 cards.

We got two linear equations here :

x + y = 7

9x + 35y = 141

Multiplying the first equation throughout by 9,

9x + 9y = 63

Subtracting the resulting equation we get from the second equation,

(9x + 35y) - (9x + 9y) = 141 - 63

35y - 9y = 78

26y = 78

y = 3

x = 7 - y = 4

Hence Ethan bought 4 hobby packs and 3 jumbo packs.
