The distance travelled by John in 13 hours is 819 miles.

The arithmetic operations are the fundamentals of all mathematical operations. The example of these operators are addition, subtraction, multiplication and division.

The total distance covered in 8 hours is 504 miles.

Then in one hour, distance covered is given as below,

⇒ Number of miles ÷ Number of hours

⇒ 504 ÷ 8 = 63

Then, the distance covered in 13 hours is given as,

⇒ Unit distance in 1 hour × Number of hours

⇒ 63 × 13 = 819

Hence, the miles travelled in 1 hour is given as 819 miles.

Answer:

x=-38

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3(x−6)−2(2x+3)=14

(3)(x)+(3)(−6)+(−2)(2x)+(−2)(3)=14(Distribute)

3x+−18+−4x+−6=14

(3x+−4x)+(−18+−6)=14(Combine Like Terms)

−x+−24=14

−x−24=14

Step 2: Add 24 to both sides.

−x−24+24=14+24

−x=38

Step 3: Divide both sides by -1.

Answer:

Slope (m) = (-1/6)

y-intercept (b) = (-3.5)

x-intercept (x) = (-21)

y = mx + b

y = (-1/6)x - 3.5

Explanation:

y = (-1/6)x - 3.5

0 =  (-1/6)x - 3.5

3.5 = (-1/6)x

(-1/6)x * -6 = x

3.5 * -6 = -21

-21 = x

Answer:

Distance between the points Q and R is 1 unit while the distance between the points R and S is 3 units

Step-by-step explanation:

Here, we want to use the absolute value of the coordinates to find the distances.

Since we are using absolute values, the negative points becomes positive;

Thus;

Q = (4,2)

R = (3,2)

S = (3,5)

Mathematically, the distance between two points in the Cartesian plane can be calculated using the formula;

D = √(x2-x1)^2 + (y2-y1)^2

The distance QR is thus;

D = √(3-4)^2 + (2-2)^2

D = √(-1)^2 + 0

D = √1 = 1 unit

The distance RS is thus;

D = √(3-3)^2 + (5-2)^2

D = √(0) + (9)

D = √9 = 3 units

The points y axis is increased by +4 if you look a the graph.

Answer:

s = [tex]\frac{4}{3}[/tex]

Answer:

81

Step-by-step explanation:

here,

(a+b)=15 -------(1)

(a-b)=12 -------(2)

Equating the equation (1) and (2)

a + b = 15

a - b = 12

(b gets cancelled having opposite signs)

or, 2a = 27

or, a = 27÷2

a = 13.5

then, putting value of a in equation (1)

a+b=15

or, 13.5 + b=15

or, b=15-13.5

b=1.5

lastly,

4ab = 4×13.5×1.5

= 81

The answers to all parts are given below.

A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -

∠x + ∠y + ∠z = 180°

The sum of two sides of a triangle is greater then the third side. Mathematically -

a + b > c

There are different types of triangles such as -

equilateral triangle , scalene triangle , isosceles triangle etc.

Given is a triangle PQR and line segment AB, which is parallel to QR.

[A] -

ΔPQR is similar to ΔPAB as -

∠P = ∠P (Common)

∠PAB = ∠PQR (Corresponding angles)

∠PBA = ∠PRQ (Corresponding angles)

Using AAA similarity rule, ΔPQR is similar to ΔPAB.

[B] -

Line segment AB corresponds to line segment QR

[C] -

∠A in ΔPAB corresponds to ∠Q.

Therefore, the answers to all parts are given above.
