Answer:

Your missing number is -87.5.

Step-by-step explanation:

You want to follow reverse order of operations to isolate your variable x

First, you plug in y= 700 to get::

700 = (24x)/7 +1000

Then subtract 1000 from both sides to get:

-300 = (24x)/7

Then multiply both sides by 7 to get:

-2100 = 24x

Then, divide by 24 to get:

-87.5 = x

Thus, your answer x= -87.5

A function with the formula f(x) = ax + b, where a and b are real values, is referred to as a linear function.

The rate of change will be 3/4.

A function with the formula f(x) = ax + b, where a and b are real values, is referred to as a linear function. Here, a stands for the line's gradient, and b for the y-axis intercept (which is sometimes called the vertical intercept).

The rate of change of y with respect to x, can be calculated utilizing any two of the pairs of values of the table, say, (3, -5) and (7, -2).

Rate of change [tex]$=\frac{y_2-y_1}{x_2-x_1}$[/tex]

Let, (3, -5) = (x1, y1) and (7, -2) = (x1, y1).

Rate of change [tex]$=\frac{(-5)-(-2)}{7-3}$[/tex]

Rate of change = 3/4.

Therefore, the correct answer is option c) 3/4.

It is to be noted that Saturn is 1.29 *x 10⁹ km further from the sun than Venus.

Recall that we are given:
approximate distance from the sun for a few different planets.  

Hence, to detect how much farther (in km) from the sun Saturn is than Venus we initiate a series of subtractions.

Recall that
Planet             approximate distance from the sun ( km)

Mercury          5.8 x 10⁷

Venus             1.1 x 10⁸

Earth               1.5 x 10⁸

Saturn             1.4 x 10⁹

The distance of Saturn form the sun and Venus is given as

= Distance of Saturn from Sun - Distance of Venus from Sun

= 1.4 x 10⁹  - 1.1 * 10⁸  [Multiply 1.4 x 10 and we've got]

= 14 x 10⁸  - 1.1 * 10⁸  

= (14 - 1.1) * 10⁸ [ Collect like terms and consolidate]

= 12.9  x 10⁸  [Revert back to the power of 9 and we have]

=  1.29 x 10⁹ km

Answer:

A goes to K. C goes to M. B goes to L.

Step-by-step explanation:

:)

The unit rate per inch on the map is 5/4 , and the length of road B is 18.75 miles.

in the question ,

it is given that ,

On the map  [tex]1\frac{1}{2}[/tex]  miles is equal to  [tex]1\frac{7}{8}[/tex] inches  .

we first convert the mixed fraction to normal fractions ,

we get

[tex]1\frac{1}{2}[/tex]  miles = (1*2+1)/2 = 3/2 miles

and

[tex]1\frac{7}{8}[/tex] inches = (8+7)/8 = 15/8 inches

So, the statement becomes

On the map  3/2  miles is equal to  15/8 inches .

So  1 mile = (15/8)/(3/2) = (15*2)/(8*3) = 30/24 = 5/4

so , the unite rate is 5/4 inches per mile .

given the road B is 15 miles long .

and the unit rate is 5/4 .

so 15 miles = 15 *(5/4) = 75/4 = 18.75 inches

Therefore , The unit rate per inch on the map is 5/4 , and the length of road B is 18.75 miles.

The given question is incomplete , the complete question is

A certain map shows two roads. Road A is [tex]1\frac{1}{2}[/tex] miles long but is [tex]1\frac{7}{8}[/tex] inches long on the map. What is the unit rate for inches per mile on this map​? If road B is 8 miles ​long, how long is road B on the map​?

Recall that the ratio 9:8 can be written as follows:

therefore, when 64 is increased in the ratio 9:8 we get:

Answer: 72.

Answer:

72

Step-by-step explanation:

Since X : 64 = 9 : 8

Then we know X/64 = 9/8

Multiplying both sides by 64 cancels on the left64 × (X/64) = (9/8) × 64

X = (9/8) × 64Then solving for X X = 64 × (9/8)X = 72

Therefore 72 : 64 = 9 : 8

Seven people sharing the rent would make the cost $120 per person.

When two quantities are inversely proportional, that is, when an increase in one causes a decrease in the other and vice versa, they are said to be inversely proportional.

The general equation for inverse variation is y = k/x, where k is the proportionality constant and x and y are two variables.

Given:

The price paid by Four friends on a ski trip to share the rent of a cabin = $210

The cost per person varies inversely with the number of persons.

Let the cost be C and the number of persons be n,

C ∝ 1/n

So, the equation becomes, k = Cn.

Putting the values in the equation we obtain the value of k,

k = 210×4 = 840

We have to find the number of people sharing the rent that would make the cost $120 per person.

Using the equation,

k = Cn

840 = 120 × n

n = 840/120 = 7

Therefore, seven people sharing the rent would make the cost $120 per person.

The approximate value of the expression given will be equal to -6.3.

An approximation may be defined bringing the value of a certain entity which is almost similar, but not exactly equal to the correct value. The expression can be written as −12 + √32. The value of √32 can be written as 5.656. Since, after decimal 6 to the right of 5 is greater than 5 so to the nearest tenth, we can write as 5.66. Therefore, √32 = 5.66

For the required value of the expression we can write,

−12 + √32

Putting the value of √32 = 5.66 in the expression we get

-12 + √32 = -12 + 5.66

After solving we get

⇒ -12 + √32 = -6.34

To the nearest tenth it will be -6.3.
