Let the number be (10 x + y)

Then, 10 x + y = 3 * (x + y) (given)

Or, 10 x + y = 3 x + 3 y

Or, 10 x - 3 x = 3 y - y

Or, 7x = 2 y

Or, x = 2 y / 7 ( Eq. 1)

Also, 10 x + y + 45 = 10 y + x ( given)

Or, 10 x - x = 10 y - y - 45

Or, 9 x = 9 y - 45 ( Eq. 2)

Substituting the value of x from (Eq. 1) in (Eq. 2), we have:

9 * 2 y / 7 = 9 y - 45

Or, (9 y ) - (18 y / 7) = 45

Or, 63 y - 18 y = 315

Or, 45 y = 315

Or, y = 7

From (Eq. 1),

x = 2 * 7 / 7 = 2

So, the number is 10 x + y = (10 * 2) + 7 = (20 + 7) = 27

Answer

Check:

Sum of the digits = 2 + 7 = 9

9 * 3 = 27 ✓

Adding 45 to the number 27, we get 72. So, the digits get reversed.

Answers

Answer:

x = 6

Step-by-step explanation:

Answer:

x=6

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

10x+4−2x=6x+9+7

10x+4+−2x=6x+9+7

(10x+−2x)+(4)=(6x)+(9+7)(Combine Like Terms)

8x+4=6x+16

Step 2: Subtract 6x from both sides.

8x+4−6x=6x+16−6x

2x+4=16

Step 3: Subtract 4 from both sides.

2x+4−4=16−4

2x=12

Step 4: Divide both sides by 2.

2x=12

Solve the equation:

7x − 2 = 26

Answers

Answer:

[tex] \large \boxed{x = 4}[/tex]

Step-by-step explanation:

Goal

Solve for x-term.

Given

Equation

[tex]7x - 2 = 26[/tex]

Step 1

Isolate x by adding 2 to both sides.

[tex]7x - 2 + 2 = 26 + 2 \\ 7x + 0 = 28 \\ 7x = 28 \\ x = \frac{28}{7} \\ x = 4[/tex]

Step 2 (Optional)

We check the answer by substituting x = 4 in the equation.

[tex]7x - 2 = 26 \\ 7(4) - 2 = 26 \\ 28 - 2 = 26 \\ 26 = 26[/tex]

The equation is true for x = 4. Hence, the solution is x = 4.

What are arithmetic Operations?

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.

Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.

As per the given data in the question,

Distance (d) traveled by the horse = 0.5 miles

Time (t) taken by the horse to cover the distance = 1.25 minutes

Then, the speed of the horse will be,

[tex]Speed=\frac{Distance}{Time}[/tex]

s = 0.5/1.25

s = 0.4 miles/minute.
