Answer: 5

Work: I just did mental math, but the proper way to do it is to get a number line, and put a dot at 2. Since you need to move three spots ahead, you move the dot three times to the right, and it will land on 5.

Answer:

it's 4.

Step-by-step explanation:

4 is the correct answer

Answer: {y,x} = {4,2} ) ) ) )4

Step-by-step explanation: y

[2] y = -2x + 8

// Plug this in for variable y in equation [1]

[1] (-2x+8) - x = 2

[1] - 3x = -6

// Solve equation [1] for the variable x

[1] 3x = 6

[1] x = 2

// By now we know this much :

y = -2x+8

x = 2

// Use the x value to solve for y

y = -2(2)+8 = 4

Solution :

{y,x} = {4,2}

The value of the expression for t will be

t = (C - p)/m

Let p = the phone’s price in dollars

m = the cost of the selected plan in dollars per month

C = Alma’s total cost in dollars after time t, measured in months of service.

Therefore, the equation that expresses C in terms of p, m, and t will be:

C = p + m(t)

To find t will be:

C = p + m(t)

Subtract p from both sides

C - p = m(t)

Divide through by m

t = (C - p)/m

Answer:

Median=(n+1/2)th item

Now,

4+1/2

=2.5

Again,

2nd item+(3rd - 2nd item) *0.5

40+(200-40)*0.5

40+160*0.5

40+80

120

Therefore, Median =120

Answer: It will take 36 minutes(0.6 hour) until both ferries depart from their docks at the same time again.

Step-by-step explanation:

Given : Ferry A departs every 1.2 hours.

Ferry B departs every 1.8 hours.

To find : Time taken by both ferries until they depart from their docks at the same time again.

= LCM (1.2, 1.8) hours   [LCM= Least common multiple]

= LCM (1.2(60 minutes), 1.8(60 minutes))    [Since 1 hour = 60 minutes]

= LCM (72 minutes, 108 minutes)

72 = 2 x 2 x 2 x 3 x 3  , 108 = 3 x 3 x 3 x 2 x 2

LCM (72,108) =2 x 2 x 3 x 3 =36

So, it will take 36 minutes until both ferries depart from their docks at the same time again.

In hour = [tex]\dfrac{36}{60}\text{ hour}=0.6\text{ hour}[/tex]

Answer:

n = 14

Step-by-step explanation:

(n + 6)4 = 5

1. multiply by 4

n + 6 = 20

2. substract 6

n = 14

The required value of n is 14 in the given sum.

Algebra is the analysis of mathematical representations, while logic is the manipulation of those symbols.

We have been given that the sum of a number, n, and 6 is divided by 4 the result is equal to 5.

According to the given question, we can write the algebraic form would be as:

⇒ (n + 6)/4 = 5

Apply the cross-multiplication operation,

⇒ (n + 6) = 5 × 4

Apply the multiplication operation,

⇒ (n + 6) = 20

⇒ n = 20 - 6

Apply the subtraction operation,

⇒ n = 14

Therefore, the required value of n is 14.

Answer:

the answer is 21

Step-by-step explanation:

21x2 = 42, 42+3 = 45

Answer: 21 cupcakes

Step-by-step explanation: x is the number of cupcakes. since she baked 45 cupcakes on tuesday, which is 3 more than 2x the number of cupcakes on monday, we would write 45=2x+3. First, subtract the 3 from both sides of the equation. This will give you 42=2x. Then divide both sides by 2. This will give you 21=x. So, the answer is 21

The grams of zinc the jar of chemical contain is 128 grams

In a certain​ chemical, the ratio of zinc to copper is 4 to 15 .

Therefore, a jar of the chemical contains 480 grams of copper.

The grams of zinc in the jar as follows:

Hence,

ratio of zinc to copper = 4 : 15

Therefore,

let

x = total grams in jar

Hence,

480 = 15 / 19 x

15x = 480 × 19

15x = 9120

x = 9120 / 15

x = 608

Therefore,

amount of zinc = 4 / 19 × 608

amount of zinc = 2432 / 19

amount of zinc = 128 grams

Answer:

y = - 3x + 5

Step-by-step explanation:

Given

6x + 2y = 10 ( subtract 6x from both sides )

2y = - 6x + 10 ( divide all terms by 2 )

y = - 3x + 5

The correct equation for y in terms of x would be, y = - 3x + 5

Hence, option 2 is true.

Used the concept of an equation that states that,

An equation is a group of numerical variables and functions that have been combined using operations like addition, subtraction, multiplication, and division.

Given that the expression is,

6x + 2y = 10

Now, simplify the equation for y in terms of x as,

6x + 2y = 10

Subtract both sides by 6x,

2y = - 6x + 10

Divide both sides by 2,

y = - 3x + 5

So, The correct equation would be, y = - 3x + 5

Thus, option 2 is true.

Answer: x° is 50°

Step-by-step explanation: The sum of the exterior angles of a polygon is 360.

Add the given exterior angles:

35+50+20+125=230

to find the missing exterior angle, supplementary to x°,

Subtract 360 - 230 = 130

The Sum of Supplementary angles is 180°

x° + 130° = 180°

Answer:

The equation of the line perpendicular to the given line is

[tex]y=\frac 1 5 x + \frac {-13}{5}[/tex].

The equation of the line perpendicular to the given line is

[tex]y=-5 x -13[/tex].

Step-by-step explanation:

The given line is y=-5x+6

The slope of the given line, [tex]m_1=-5[/tex]

Let [tex]y= m_2 x + C_2[/tex] be the slope of the line perpendicular to y=-5x+6,

where [tex]C_2[/tex] is constant.

As multiplication of slopes of two perpendicular lines equal to -1, so

[tex]m_1m_2=-1 \\\\\Rightarrow -5\times m_2= -1 \\\\\Rightarrow m_2= \frac {-1}{-5}= \frac 1 5[/tex]

So, the equation of the line perpendicular to the given line is

[tex]y=\frac 1 5 x +C_2[/tex] which passes through the point (-2,-3), so

[tex]-3=\frac 1 5 (-2) +C_2 \\\\\Rightarrow C_2 = -3 +\frac 2 5= \frac {-13}{5}[/tex]

Hence, the equation of the line perpendicular to the given line is

[tex]y=\frac 1 5 x + \frac {-13}{5}[/tex].

Now, let [tex]y=m_3 x +C_3[/tex] be the equation of the parallel line to y=-5x+6.

As the slopes of two parallel lines are the same, so [tex]m_3=-5[/tex].

So, the equation of the parallel line becomes

[tex]y=-5 x +C_3[/tex] which passes through the point (-2,-3), so

[tex]-3=-5 (-2) +C_3 \\\\\Rightarrow C_2 = -3 - 10 = -13[/tex]

Hence, the equation of the line perpendicular to the given line is

[tex]y=-5 x -13[/tex].

Answer:

The value of x depends on the amount the length is going to run to.

Step-by-step explanation:

Answer:

58 square units

Step-by-step explanation:

Take the shaded figure as a full larger rectangle minus the rectangular part which is not shaded.

Area of the full larger rectangle:

Area = length × width

Length = |12 - 2| = 10 units

Width = |8 - 1| = 7 units

Area = 10 × 7 = 70 units²

Area of the unshaded small rectangle:

Length = |10 - 4| = 6 units

Width = |3 - 1| = 2 units

Area = 6 × 2 = 12 units²

Area of the shaded figure = 70 - 12 = 58 square units
