Answer: 56.2 miles

Step-by-step explanation:

5.95+0-25x less or equal 20

0.25x less or equal 20 - 5.95

0.25x less or equal 14.05

X less or equal 14.05/0.25

X = 56.2

Katie can travel at most 56.2 miles in $20.

A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions is called inequality.

According to the given question.

The total money Katie have = $20.

Amount charged by cab taxi for ride = $5.95

Charges for per mile ride = $0.25

Let Katie travel x miles without exceeding her expending limit.

From the given condition we get a inequality

[tex]20\geq 5.95+0.25x[/tex]

Solve the above inequality for x.

⇒[tex]20 - 5.95\geq 0.25x[/tex]

⇒ [tex]14.05\geq 0.25x[/tex]

⇒[tex]x\leq \frac{14.05}{0.25}[/tex]

⇒[tex]x\leq 56.2miles[/tex]

Katie can travel at most 56.2 miles in $20.

Answer:

the answer is 1 : 2.4 because for every 1 inch on the original image there are 2.4 inches on the modified image.

Step-by-step explanation:

Step 1:

Measure the change in X and Y of a single length of the original image.

X1 = 3.5

Y1 = 5

Step 2:

Measure the change in X and Y of the same length on the modified image.

X2 = 8.5

Y2 = 12.5

Step 3:

use formula SF = X2/X1 = Y2/Y1

(SF = Scale Factor Dilation)

(X2 and Y2 = change in X and Y of the same length on the modified image.)

(X1 and Y1 = change in X and Y of a single length of the original image.)

X2 = 8.5

8.5/X1

X1 = 3.5

8.5/3.5

8.5/3.5 = 2.4

2.4

1 : 2.4

Answer:

Answer = -34

Step-by-step explanation:

B = 4 ; y = -6

So,

-4 + (5) (−6)

= −4 + −30

= −34

Hope you get it :)

The value of expression will be;

⇒ - 34

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ - b + 5y

And, The values are,

⇒ b = 4, y = - 6

Now,

Since, The expression is,

⇒ - b + 5y

Substitute  b = 4, y = - 6, we get;

⇒ - 4 + 5 × - 6

⇒ - 4 - 30

⇒ - 34

Thus, The value of expression is,

⇒ - 34

Answer:

m<ABC = 92

Step-by-step explanation:

(3x + 23) and 4x are equal angle wise. So we have the equation:

(3x + 23) = 4x

3x = 4x - 23

-x = -23

x = 23

Multiply x by 4 which is 92

Answer:

There are 12 horses and 18 geese.

Step-by-step explanation:

We are given that in a field full of horses and geese, a farmer notes that there are 30 heads and 84 feet.

We can write a system of equations using the given information.

Let the amount of horses there are be represented by h and geese by g.

Assuming each horse and geese has only one head, we can write that:

[tex]\displaystyle h + g= 30[/tex]

And assuming that each horse has four feet and each geese has two feet, we can write that:

[tex]4h + 2g = 84[/tex]

This yields a system of equations:

[tex]\displaystyle \left\{\begin{array}{l} h + g = 30 \\ 4h + 2g = 84 \end{array}[/tex]

We can solve it using substitution. From the first equation, isolate either variable:

[tex]g = 30 - h[/tex]

From the second, we can first divide by two:

[tex]2h + g = 42[/tex]

And substitute:

[tex]2h + (30 - h) = 42[/tex]

Combine like terms:

[tex]h + 30 = 42[/tex]

Subtract:

[tex]h = 12[/tex]

Therefore, there are 12 horses.

And since the total number of animals is 30, there must be 30 - 12 or 18 geese.

In conclusion, there are 12 horses and 18 geese.
