what’s the answer to :
12x+8x+3+x ?

Answer:

10

Step-by-step explanation:

The measure of an angle∠I  is 10 degrees between the 450 cm and 640 cm sides.

The Law of Cosines (also called the Cosine Rule) is defined as it relates all three sides of a triangle with an angle of a triangle.

c² = a² + b² − 2ab cos(C)

The cosine rule, also known as the law of cosines, relates all 3 sides of a triangle with an angle of a triangle. it relates the lengths of the sides of a triangle to the cosine of one of its angles.

In the given triangle ΔHIJ,

Sides:

h = 450 m

i = 210 m

j = 640 m

The angle of ∠I  is 10 degrees between the 450 cm and 640 cm sides.

According to the cosine rule,

j² = h² + i² − 2ab cos(I)

Substitute the values in the Cosine Rule,

450² = 210² + 640² - 2(210)(640)cos(I)

After solving we get the value of  angle ∠I :

∠I = 9.56038°

Rounded to the nearest degree.

∠I = 10°

Thus, the measure of an angle∠I  is 10 degrees.

Answer:

x= [tex]\frac{19}{8}[/tex]

Step-by-step explanation:

8(x−3)−(6−2x)=2(x+2)−5(5−2)

Step 1: Simplify both sides of the equation.

8(x−3)−(6−2x)=2(x+2)−5(5−2)

8(x−3)+−1(6−2x)=2(x+2)−5(5−2)(Distribute the Negative Sign)

8(x−3)+(−1)(6)+−1(−2x)=2(x+2)−5(5−2)

8(x−3)+−6+2x=2(x+2)−5(5−2)

(8)(x)+(8)(−3)+−6+2x=(2)(x)+(2)(2)+−5(5−2)(Distribute)

8x+−24+−6+2x=2x+4+−15

(8x+2x)+(−24+−6)=(2x)+(4+−15)(Combine Like Terms)

10x+−30=2x+−11

10x−30=2x−11

Step 2: Subtract 2x from both sides.

10x−30−2x=2x−11−2x

8x−30=−11

Step 3: Add 30 to both sides.

8x−30+30=−11+30

8x=19

Step 4: Divide both sides by 8.

8x/8=19/8

Answer: x=[tex]\frac{19}{8}[/tex]

8(x - 3) - (6 - 2x) = 2(x + 2) - 5(5 - 2)

8*x - 8*3 - 6 + 2x = 2*x + 2*2 - 5*3

8x - 24 - 6 + 2x = 2x + 4 - 15 ( Cancel equal terms on both sides of the equation)

8x - 24 - 6 = 4 - 15

8x - 30 = -11

8x = -11 + 30

8x = 19

x = 19/8

246.8/128= 1.928

The speed of the boat is 7 miles/hour and the current of the river is 1 mile/hour.

Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.

We have:

A boat goes 24 miles at a constant speed in 4 hours against a river current.

It takes the boat 3 hours to go the same distance at the same speed with the current of the river.

Let's suppose the speed of the boat is x miles/hour and the current of the river is y

x- y = 24/4

x - y = 6 ..(1)

x + y = 24/3

x + y = 8  ..(2)

Adding equation (1) and (2):

2x = 14

x = 7 miles/hour

y = 8 - 7 = 1 miles/hour

Thus, the speed of the boat is 7 miles/hour and the current of the river is 1 mile/hour.

Step-by-step explanation:

Answer: chemical decomposition produced by passing an electric current through a liquid or solution containing ions. In chemistry and manufacturing, electrolysis is a technique that uses direct electric current to drive an otherwise non-spontaneous chemical reaction. Electrolysis is commercially important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell. Electrolysis is used in industry for the production of many metals and non-metals (e.g., aluminium, magnesium, chlorine, and fluorine). Electrolysis is commonly employed for coating one metal with another. The method of coating one metal with another using an electric current is called electroplating.

Step-by-step explanation:

8.3÷0.25

Multiply that by 30 and you get 996

The actual distance between the two cities will be 996 miles.

Distance is defined as the product of speed and time.

Scale is defined as a ratio that represents the relationship between the shape and size of a figure and the corresponding dimensions of the actual figure or object.

The given scale is 0.25 inches on the map representing 30 miles.

If the distance between two cities is 8.3 inches

As per the given scale, the actual distance between the two cities will be as:

⇒ 8.3 × 30/0.25

⇒ 83/10 × 3000/25

⇒ 249,000/250

Apply the division operation, and we get

⇒ 996 miles

Step-by-step explanation:

First, we must determine the slope, then we find the y-intercept using slope formula and slope-intercept form.

For slope:

[tex]m = \frac{5 + 2}{-3 + 4} = \frac{7}{1} = 7[/tex]

Slope (m) = 7

For y-intercept:

[tex]5 = 7(-3) + b\\\\5 = -21 + b\\\\26 = b[/tex]

Y-intercept (b) = 26

Using this information, we can now create the equations for this line.

[tex]y= 7x + 26\\\\y - 5 = 7(x + 3)[/tex]

Formulas:

Slope formula: y₂ - y₁/x₂ - x₁

Slope-intercept form: y = mx + b

Point-slope form: y - y₁ = m(x - x₁)

*Note: (x₁, y₁), (x₂, y₂) = 2 points on the line
