Answer:

it is IH - 110 ft

Step-by-step explanation:

The plane height is down 110 feet from its initial height.

Subtraction is mathematic operation. Which is used to remove terms or objects in expression.

Let x be the initial height of the plane.

Then according to question;

if drop down means height in negative term and rise up means height in the positive term.

Then,

the height is

= x -300-180+240+130

= x-110

Therefore, down 110 feet is the height of the plane now relative to its initial height.

The value that is equal to the average rate of change of the function over the interval is equal is 1 m/s

Given the position of the object expressed as:

y = -t^2 + 3t - 4

In order to calculate the value that is equal to the average rate of change of the function over the interval (0, -4) and (2, -2), we will determine the slope of these two coordinates as shown;

Rate of change = -2-(-4)/2-0
Rate of change = -2+4/2
Rate of change = 2/2

Rate of change = 1 m/s

Hence the value that is equal to the average rate of change of the function over the interval is equal is 1 m/s

By standard notation, if May wins money, then we represent this with a positive number.

While if she pays or has a debt, we represent the change with a negative number (because now she has less money than before).

A) She receives $25, so the change is:

C = $25

B) She earns $14, so the change is:

C = $14

C) She spends $10, so now she has $10 less than before, the change is:

C = -$10

Answer:

x + 8 = 20

Step-by-step explanation:

Using the keywords;

'more than' (addition)

'a number' which we can consider a variable

and 'equals'

Answer: 8 + x =20

Step-by-step explanation: eight more than a number means 8 more than meaning plus, a number. So this is saying that 8 more than what ever that number is, will equal 20. We say x in the equation because x can be see as “the number”.

x = “the number” = 12

This is because 8 more than 12 is 20...

So 8 more than a number = 8 + x = 20

According to the Question :

⠀

Subracting x from both sides we get :

[tex]{ \longrightarrow {\qquad {\sf 4x= \cancel{x} \: \: \cancel{- x}+ 24 }}}[/tex]

[tex]{ \longrightarrow {\qquad {\sf 4x= 24 }}}[/tex]

⠀

Dividing both sides by 4 we get :

Therefore,

Step-by-step explanation:

x = number of t- shirts

the function for the incurring costs is

c = 5x + 45

the function for the accumulating sale is

s = 20x

the break even point is when both functions deliver the same result.

20x = 5x + 45

15x = 45

x = 3

c = s = 5×3 + 45 = 20×3 = $60

they need to sell 3 t-shirts to break even.

at that point they will have incurred $60 in costs and collected the same amount in sales.

Find 60 percent of 40.

Percent means over 100

Multiply that by 40 to find 60% of it:

40 * 0.6 = 24

A Samantha spent percent 24 minutes on language arts out of the 40 minutes dedicated to her homework.

To find the number of minutes Samantha spent on language arts,  to calculate 60% of the total time  spent on homework.

Samantha spent a total of 40 minutes on homework.

To find 60% of 40 minutes, multiply 40 by 0.60 (since 60% is equivalent to 0.60):

60% of 40 = 0.60 × 40 = 24 minutes

Therefore, Samantha spent 24 minutes on language arts.

First, combine like terms:

4x -58 +x =2 can be rewritten as 5x - 58 =2

Next, isolate the x on one side of the equation by adding 58 to both sides:

5x = 60

The number of people that went to the amusement park consisted of 26 students and 16 adults.

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x is the number of students and y is the number of adults. The bus of 42 people paid $1080 to enter the amusement. Hence:

x + y  = 42   (1)

Also:

20x + 35y = 1080    (2)

Step 5: Divide both sides of the equation by the same term.

Step 6: Simplify.

X=10 :)

Answer:

Step-by-step explanation:

In this question we are given an equation that is 22x + 100 = 25x + 70. And we are asked to find the value of x .

Solution : -

[tex] \longmapsto \:22x + 100 = 25x + 70 [/tex]

Step 1 : Subtracting 100 from both sides :

[tex] \longmapsto \:22x + \cancel{100} - \cancel{100} = 25x + 70 - 100[/tex]

On further calculations we get :

[tex] \longmapsto \: 22x = 25x - 30[/tex]

Step 2 : Subtracting 25x from both sides :

[tex] \longmapsto \:22x - 25x = \cancel{ 25x} - \cancel{25x }- 30[/tex]

On further calculations we get :

[tex] \longmapsto \: \cancel{- }3x = \cancel{ - }30[/tex]

Step 3 : Dividing with 3 on both sides :

[tex] \longmapsto \: \frac{ \cancel{3}x}{ \cancel{3}} = \cancel{\frac{30}{3} }[/tex]

On further calculations we get :

have a good day.

Answer:

True.

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. Multiply the reciprocal of the fraction to both sides to isolate the variable, v.

The reciprocal in math is described as the quantity that is multiplied that will result in 1. In this case, you will multiply 5/2 to both sides of the equation:

[tex]\frac{2}{5}v = 4\\ \\(\frac{5}{2})\frac{2}{5}v = 4 * (\frac{5}{2})\\[/tex]

[tex]v = \frac{4 * 5}{2} = \frac{20}{2} = 10\\ v = 10[/tex] (True).

In this case, v = 10 will work to solve the given equation, and so it is true.
