is this proportional relationship? please help!!

Answer:

x = 6

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Equality Properties

Algebra I

Step-by-step explanation:

Step 1: Define Equation

2(x + 2x) = 36

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 36 does indeed equal 36.

∴ x = 6 is the solution to the equation.

Answer :

2(x+2x)=36

2x + 4x =36

6x =36 is the answer

umm... i need a problem or anything bud

Step-by-step explanation:

Answer:

D. 14.

Step-by-step explanation:

As we know, 10 to the second power is 100, to the third power is 1000, and so on. These powers add a zero to the number. Since PEMDAS tells us to do exponents before multiplication, we need to find what power of 10 gives us 100,000,000,000,000. Let's count all the zeros. There are 14 zeroes. This means our answer is D. 14. Let's check, though. 10 to the 14th power is 100,000,000,000,000, and that times 3 is 300,000,000,000,000. That means our answer is correct, it is in fact, D. I hope this helps!

Edit: I changed the answer from 13 to 14 because I realized that 13 is incorrect.

Answer:

(-38,18)

Step-by-step explanation:

Step: Solvex+3y=16for x:

x+3y+−3y=16+−3y(Add -3y to both sides)

x=−3y+16

Step: Substitute−3y+16forxin2x+5y=14:

2x+5y=14

2(−3y+16)+5y=14

−y+32=14(Simplify both sides of the equation)

−y+32+−32=14+−32(Add -32 to both sides)

−y=−18 Divide both sides by -1

[tex]\frac{-y}{-1} =\frac{-18}{-1}[/tex]

y=18

Step: Substitute18foryinx=−3y+16:

x=−3y+16

x=(−3)(18)+16

x=−38

The cross-sectional area of the shaft is 314 mm²

The outside diameter (d₂) = 6 cm = 60 mm

The inside diameter (d₁) = 4 cm = 40 mm

The cross sectional area of the shaft (A) is given by:

A = π(d₂ - d₁)²/4

Substituting values:

A = π(60 - 40)²/4

Simplifying the equation:

A = 314 mm²

The cross-sectional area of the shaft is 314 mm²

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Table is shown in figure.

Two points on the table are (3, 0) and (4, 1).

Now,

Since, The equation of function passes through the points,

(3, 0) and (4, 1).

So, We need to find the slope of the function.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (1 - 0) / (4 - 3)

m = 1

Thus, The equation of function with slope 1 is,

⇒ y - 0 = 1 (x - 3)

⇒ y = x - 3

⇒ y = x - 3

Thus, The equation of function notation for the relation will be,

⇒ y = x - 3

Answer:

FV= $1,545

Step-by-step explanation:

Giving the following information:

Elena deposits $1,500 in a savings account that earns 3.0% simple interest per year.

To calculate the nominal value of the account after one year, we need to use the following formula:

FV= (P*r*t) + P

FV= future value

P= principal

r= interest rate

t= 1

FV= (1,500*0.03*1) + 1,500

FV= $1,545

Answer:

14.83 meters

Step-by-step explanation:

Given that :

Angle of elevation (α) = 56°

Distance between observer and foot of tree = 10 meter.

Height of tree =?

Using trigonometry :

The height (h) of the tree can be obtained using :

Tan α = opposite / Adjacent

Tan(56°) = h / 10

1.4825609 = h / 10

Multiply both sides by 10

1.4825609 * 10 = h

14.8256 = h

Hence, the height of the tree is 14.83 m(2 decimal places).
