your equation I believe would be
x = (1056.5 - 470)/ 69
Explanation:
First you would need to find how much money was charged for labor, so you needed to subtract 470 from the total.
Second, once you find the amount charged for labor, you would need to divide the hourly rate by that number. That would give you the number hours.

-2x-20

Step-by-step explanation:

Answer:

-2x-20

Step-by-step explanation:

Expand 3(x-5) : 3x-15

Do not forget there is a subtraction sign in the middle.

Expand 1/2(10x+10) : 5x+5 : 5(x+1)

= 3x - 15 - 5(x+1)

Expand -5(x+1) : -5x-5

= 3x-15 - 5x - 5

Simplify 3x-15-5x-5 by adding like terms: -2x-20

= -2x-20

A gardener fills a 2 1/2 cubic foot wheelbarrow 2/3 of the way without soil weight 75.25 pounds. What is the weight of the soil un wheelbarrow?​

Answers

Volume of wheelbarrow , V = 2 1/2 ft³ = 5/2 ft³.

Volume of soil in wheelbarrow , [tex]v = \dfrac{5}{3}\ ft^3[/tex] .

Mass of soil in wheelbarrow , m = 75.25 pounds.

Now, volume left , [tex]v'=\dfrac{5}{6}\ ft^3[/tex] .

Let, mass of  soil un wheelbarrow is x.

[tex]x=\dfrac{\dfrac{5}{6}\times 75.25}{\dfrac{5}{3}}\\\\x=37.625\ pounds[/tex]

E. The measure of angle BCD is the same as the measure of angle GFE.
True/false

Answers

Answer: True, False, False, True, False

Step-by-step explanation:

Since the two quadrilaterals are similar, for question A your answer of True is correct since EF would scale to be twice as long as AB. For the second question the reverse logic applies. For Question C EH is 16 units since 8x2 is 16. For the last question, since BCD does not corresponds to GFE, it is false. Angle BCD has a vertex at point C and GFE has a vertex at point F. Since C does not correspond to F, the angles are not the same.

Can somebody help me out on this question I would really appreciate it so much . Please and thank you .

Answers

Step-by-step explanation:

AB = AC, so mark the two sides with single tick marks.

m∠ACD = 128°, so label the angle 128°.

∠ACB is supplementary to ∠ACD, so:

m∠ACB + m∠ACD = 180°

m∠ACB + 128° = 180°

m∠ACB = 52°

ΔABC is an isosceles triangle, so m∠B = m∠ACB.

m∠B = m∠ACB

m∠B = 52°

Angles of a triangle add up to 180°, so:

m∠A + m∠B + m∠ACB = 180°

m∠A + 52° + 52° = 180°

m∠A = 76°

The domain of any polynomial function is the set of Real numbers, And as far as the Range, we decide based on its end-behavior: since this is a polynomial with leading term [tex]x^3[/tex], then it has the property of getting to infinitely large values for increasing values of x, and infinitely negative values for decreasing values of x.

The quotient of a number and 17 is 118.82.

A. it can be solved with division property of equality.

B. It can be solved with the multiplication property of equality

C. The equation should x/17=118.82

D.x=7

E. X=2020

Answers

Answer:

C. The equation should x/17=118.82

Step-by-step explanation:

We know that

Dividend ÷ Divisor = Quotient

Dividend/Divisor = Quotient

From the question, we are told that:

The quotient of a number and 17 is 118.82

Let us represent the unknown number as x = Dividend

17 = Divisor

Quotient = 118.82

Hence,

x / 17 = 118.82

Cross Multiply

x = 17 × 118.82

x = 2019.94

The correct answer = Option C. The equation should x/17=118.82

For an indirect proof, what must first be assumed to prove that LaTeX: \angle X∠ Xis a right angle?

Answers

Answer:

If the lines that forms < X are perpendicular, it can be assumed that it is a right angle.

Step-by-step explanation:

An indirect proof of an angle is an assumption about the value of the angle that can be made by mere inspection and some considerations.

                                     < X = right angle =  [tex]90^{o}[/tex]

A right angle is one that is equal to [tex]90^{o}[/tex]. As an indirect proof, if the lines that forms the angle are perpendicular; then it can be assumed to be a right angle. Because perpendicular lines are at right angle to one another.

Determine whether the given segments have the same length. Drag and drop each number
into the correct box to complete the justification of your answer. BC and EF

Answers

Answer:

Step-by-step explanation:

Length of a segment between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Coordinates of extreme ends of BC and EF are,

B(1, 4), C(3, -2), E(-3, -2) and F(-1, 1)

Length of BC = [tex]\sqrt{(1-3)^2+(4+2)^2}[/tex]

                      = [tex]\sqrt{4+36}[/tex]

                      = [tex]2\sqrt{10}[/tex] ≈ 6.32 units

Length of EF = [tex]\sqrt{(-3+1)^2+(-2-1)^2}[/tex]

                     = [tex]\sqrt{4+9}[/tex]

                     = [tex]\sqrt{13}[/tex] ≈ 3.61 units

The length of BC is 6.32. The length of EF is 3.61.So, BC and EF don't have the same length.

Answers

square root of - does not exist in the set of real numbers

Your question has been heard loud and clear

√-36 is by no means a real number. This is because square roots can only be positive in nature.  

Eg:  -2*-2 =  4      and 2*2 = 4   ,  so √4 =  -2 or 2   but √-4 doesnt exist.

So , √-36 also does not exist while √36 exists.

√-36 , we can however represent it as an imaginary number as 36i

7. Identify the explicit formula for the sequence given by the recursive formula

Answers

Answer:  B) f(n) = 30 - 8(n - 1)

Step-by-step explanation:

Explicit formula is of the form: [tex]a_n=a_1+d(n-1)[/tex]    where

[tex]a_1[/tex] is the first term d is the difference between consecutive terms

Given: f(1) = 30  --> this represents the first term [tex]a_1[/tex] = 30

          f(n - 1) - 8   --> this means the previous term minus 8 thus d = -8

[tex]a_n[/tex] = 30 + (-8)(n - 1)
