Calculate the acceleration of gravity on the surface of Mars
Express your answer with the appropriate units.

x = one number

x + 1 = second number

x + x + 1 = 129

Combine like terms

2x + 1 = 129

Subtract 1 from both sides.

2x = 128

Divide both sides by 2

x = 64

The locker numbers are 64 and 65

Answer:

You are correct

Step-by-step explanation:

Hi,

[tex](f+g)(x)=6x-12+3x+8=9x-4\\\\(f-g)(x)=6x-12-3x-8=3x-20[/tex]

Thanks

Answer: Let your no.= x

double the number=2x

add 4 = 2x+4

subtract same number=2x+4-x

subtract 3=2x+4-x-3

I get my number plus 1=x+1

so equation we get

2x+4-x-3=x+1

x+1=x+1

x=x

it means  x is equal to all real number

So your number can be any real number

Answer: $4.75.

Step-by-step explanation:

It is given that a news offers a subscription that costs $28.50 for 6 months.

We need to find the unit price per month.

The formula for unit price per month is

[tex]\text{Unit price per month}=\dfrac{\text{Total subscription cost}}{\text{Number of months}}[/tex]

[tex]\text{Unit price per month}=\dfrac{28.50}{6}[/tex]

[tex]\text{Unit price per month}=\dfrac{285}{60}[/tex]

[tex]\text{Unit price per month}=4.75[/tex]

Therefore, the unit price per month is $4.75.

Answer and Explanation:

Solution: The operation of concatenation for a set of string on p. and the set is

     AB = {XY | X ∈ A and y ∈ B}.

We need to satisfy all these following properties to find out the standard set is closed under concatenation.

1- Union of two standard sets also belongs to the classic collection. For example, A and B are regular. AUB also belongs to a regular group.

2- Compliment of two standards set A and B are A’ and B’ also belonging to the standard set.

3- Intersection of two standards set A and B is A∩B is also a regular set member.

4- The difference between two regular sets is also standard. For example, the difference between A and B is A-B is also a standard set.

The closure of the regular set is also standard, and the concatenation of traditional sets is regular.

Answer:

36,750.

Step-by-step explanation:

The way to determine the number that is seven hundred times greater than 5.25 is by multiplying those numbers, the result being the number in question.

Thus, the following multiplication must be performed:

700 x 5.25 = X

3,675 = X

Thus, the number that is seven hundred times greater than 5.25 is 3,675.

Answer:

x is in the range [-1,4]

Step-by-step explanation:

I haven't worked with absolute value inequalities in awhile, but let's take a wack at this.

We are given the following inequality:

| 2x - 3 | <= 5

This implies two possible cases:

[1] -5 <= 2x -3

Or

[2] 2x - 3 <= 5

So let's solve x for both of these cases:

[1] -5 <= 2x - 3

 -2 <= 2x

 -1  <= x

[2]  2x - 3 <= 5

 2x <= 8

  x <= 4

So from these cases, we can say the following is true:

x >= -1  and x <= 4

Thus, we can write this in the form

-1 <= x <= 4

Or in interval notation:

{ x is element of reals | -1 <= x <= 4}

Also written as

x is in the range [-1,4]

Where the closed brackets represent 1 and 4 as possible answers whereas parenthesis would imply they were not.

Cheers.

Answer:

The temperature when Emily went to bed was -4°F.

Step-by-step explanation:

8°F + 3°F = 11°F (noon)

The temperature had risen by 3°F by noon. This means to add 3.

noon + 6°F = the day's high temperature

11°F + 6°F = 17°F (the day's high temperature)

The temperature rose another 6°F in the afternoon. This means add 6 to the temperature from noon.

high temperature - 21°F = temperature at bed

17°F - 21°F = -4°F

The temperature dropped by 21°F when Emily went to bed. This means to subtract 21 from the day's high temperature.  

Risen, rose, and increase mean addition.

Decrease, dropped, and decline mean subtraction.

Answer:

-3/2

Step-by-step explanation:

Since we have two points, we can use the slope formula

m = ( y2-y1)/(x2-x1)

   = ( 7-4)/(1-3)

   = 3/-2

  = -3/2

Answer:

The answer is

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

[tex]m = \frac{y_{2} -y_{1}}{x_{2} -x_{1} } [/tex]

where

(x1 , y1) and (x2 , y2) are the points

m is the slope

From the question the points are

(3,4) and (1,7)

The slope is

[tex]m = \frac{7-4}{1 - 3} \\ = - \frac{3}{2} [/tex]

We have the final answer as

[tex] - \frac{3}{2} [/tex]

Answer:

y=7/36

Step-by-step explanation:

Since y varies inversely to the square of x, we can say

[tex]y = z/x^2[/tex]

where z is the constant of variation.

Then, from knowing that y=7/4 when x=1, we plug them in to find z.

[tex]7/4=z/(1^2)\\z=7/4[/tex]

Now we have the full equation,

[tex]y=7/4x^2[/tex]

Plug x=3 in and we get,

[tex]y=7/4(3^2) = 7/36[/tex]

Step-by-step explanation:

Answer:

[tex]P=400000(2^t)-40000t[/tex]

Step-by-step explanation:

The initial number of mosquitoes is 400000, and they double each day. This represents an exponential growth equation. If t represent days and P represent the population of the mosquitoes, hence this can be represented by the equation:

[tex]P=400000(2^t)[/tex]

Also, the predators eat the mosquitoes at a rate of 40,000 mosquitoes/day. This means that each day, the mosquitoes reduce by 40000t, therefore this can be represented by:

[tex]P=400000(2^t)-40000t[/tex]
