Answer 1

Answer:

x = 48

Step-by-step explanation:

first you would add them together and set it equal to 180( because a straight line is 180 degrees): 3x - 12 + x = 180

Then you add like terms( the x's): 4x - 12 = 180

now add 12 to both sides: 4x = 192

now divide by 4 on both sides x = 48

hope this helps! : )

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.

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.

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.

Above lone woodland ways that led To dells the stealthy twilights tread The west was hot geranium red; And still, and still, Along old lanes the locusts sow With clustered pearls the Maytimes know, Deep in the crimson afterglow, We heard the homeward cattle low, And then the far-off, far-off woe Of "whippoorwill!" of "whippoorwill!"II. Beneath the idle beechen boughs We heard the far bells of the cows Come slowly jangling towards the house; And still, and still, Beyond the light that would not die Out of the scarlet-haunted sky; Beyond the evening-star's white eye Of glittering chalcedony, Drained out of dusk the plaintive cry Of "whippoorwill," of "whippoorwill."III.
