Answer:

North Route is 20 miles, and South Route is 25 miles.

Step-by-step explanation:

Let the length of the North route be represented by x and that of the South route be represented by y.

On Monday,

8x + 10y = 410

On Tuesday,

15x + 11y = 575

So that,

8x + 10y = 410 .............. 1

15x + 11y = 575 ......... 2

Using substitution method, from equation 1;

x = [tex]\frac{410 - 10y}{8}[/tex] ................. 3

Substitute the expression for x into equation 2,

15([tex]\frac{410 - 10y}{8}[/tex]) + 11y = 575

multiply through by 8,

6150 - 150y + 88y = 4600

6150 - 62y = 4600

6150 - 4600 = 62y

1550 = 62y

divide through by 62 to have,

y = 25

Substitute the value of y in equation 3

x = [tex]\frac{410 - 10y}{8}[/tex]

  = [tex]\frac{410 - 10(25)}{8}[/tex]

  = 20

x = 20

Thus, North Route is 20 miles, and South Route is 25 miles.

Answer:

-2.25

Step-by-step explanation:

9(1-x) = 27Y

9-9x =27y

-9x -27y = -9  multiply all terms by -1

9x +27y =9   equation (1)

x-y= -11/2 equation (2)

by solving 2 equations

x= -3.875

y= 1.625

∴ x+ y = 1.625 +(-3.875) = -2.25

Algebra I

Step-by-step explanation:

Step 1: Define Equation

2x + 3 + 4x = 6x + 3

Step 2: Solve for x

Here we see that x does indeed equal to x.

∴ x = infinite amount of solutions.

2x + 3 + 4x = 6x + 3

Combine the like terms on the left side

2x + 4x = 6x

6x + 3= 6x + 3

Subtract 3 from each side

6x = 6x

Divide each side by 6

x = x

No matter what x is, they are the same. It has infinite solutions.

first lets see how much is 40% of 6.30

(6.30*40)/100=2.52

he will resell the shoes with

6.30+2.52=8.82

Answer:

$[tex]8.82[/tex]

6x²-x-2

Answer:

22 units

Step-by-step explanation:

The formula for the area of a trapezoid is A = [tex]\frac{a+b}{2} h[/tex] where a and b are the bases and h is the height of the trapezoid.

In this case, the numbers that will be replacing a and b will be 4 and 7, making the equation look like this: A = [tex]\frac{4+7}{2}h[/tex] .

Now, you have to determine the height of the trapezoid, which in this case is 4 units. The equation will now look like this: A = [tex]\frac{4+7}{2}4[/tex].

You can solve from here like so:

A = [tex]\frac{11}{2}4[/tex]

A = 5.5(4)

A = 22

I got the measurements like 4, 7, and the other 4 from rotating the shape to have the longer side on the bottom.

Step-by-step explanation:

The total book checked out by Han will be equal to 8 which is 4 less than Jada.

The four basic mathematical operations are the addition, subtraction, multiplication, and division of two or even more integers. Among them is the examination of integers, particularly the order of actions, which is crucial for all other mathematical topics, including algebra, data organization, and geometry.

As per the given information in the question,

Total books checked out Jada = 12

Han has 1/3 less than Jada so,

12 × 1/3

= 4 books less than Jada.

So,

12 - 4 = 8 books checked out Han.

Answer:

(16, 6)

Step-by-step explanation:

The coordinate of an ordered pair is often represented as (x, y). That is, when x is equal to a particular value, the value of y would be the corresponding value to x on the coordinate plane.

So, given an incomplete ordered pair, (16, ), to find the missing coordinate, trace the value of y that corresponds to the value of x = 16.

That is, what is the value of y when x = 16.

From the plot, when x = 16, y = 6. The missing coordinate is 6.

Thus, we would have:

(16, 6).

Answer:

( 9, -35 )

Step-by-step explanation:

We can figure out how far the midpoint is from point A and just add the same values to the midpoint's coordinates to get the location of point B.

From A to Midpoint in the X direction:

+ 6

From A to Midpoint in the Y direction:

-15

The coordinate of the midpoint is:

( 3, -20)

3 + 6 = 9

-15 + (-20) = -35

The coordinates of B are:

( 9, -35 )

Step-by-step explanation:

7^-2 = 1/7^2

The negative means you flip it

1/7^2 times 7^6 is 7^6/7^2 (just multiply).

using rules of exponents, 7^6/7^2 is 7^4 (just subtract 2 from 6)

D is the only one that equals 7^4, as 2 times 2 is 4.

Answer:

C) 115 degrees

Step-by-step explanation:

A line is 180 degrees.

This means that the other side of the line with an angle of 115 degrees will be 180-115=65 degrees.

The angle above that will be 115 and the other will be 65.

Line v is similar to line u. This means that it is 115 degrees because the question mark is at the spot that is 115 degrees in the above angles.

Step-by-step explanation:

We can get this by simplifying the inequalities

3(x-4) ≤ 18

3x - 12 ≤ 18

3x ≤ 18 + 12

3x ≤ 30

x ≤ 30/3

x ≤ 10

Secondly;

2(x-1) ≥ 6

2x - 2 ≥ 6

2x ≥ 6 + 2

2x ≥ 8

x ≥ 4

So the possible answer that fits both cases is 9

12 won’t work as it is not less than 10; we need an answer that is less than 10 to satisfy the first inequality

Answer:

Total = 800 books

Step-by-step explanation:

It is given that,

In a library, there are 3 non-fiction books for every 7 fiction books. It means that the ratio of non-fiction books to the fiction books is 3:7.

There if the library has 240 non-fiction books.

Let non fiction books are 3x and fiction books are 7x.

ATQ,

3x=240

x=80

Fiction books = 7x = 7(80) = 560

Total no of books = fiction books + non-fiction books

= 240 + 560

=800

Hence, the total no of books are 800.
