Answer:

The mistake is in step 1 when you do -2(x+4) you do the distributive property first -2 times x is -2x that's correct but -2 times 4 is not 8 it is -8

when you multiply by negatives the answer will always be a negative unless your multiply 2 negative number together then itll be positive ex. 4 × -4 = -16 (negative) but -4 × -4 = 16 (positive)

Answer:

Step-by-step explanation:

i think it 8.45

Answer:

To solve this question, all we have to do is  to convert - 8 5/12 to a decimal.

So we have: -8 5/12 = -8. (5/12)

This is equal to -8.41666... , where the 6 continues forever. You can express this by drawing a line above the 6, which indicates that it continues forever.

Answer:

[tex] \frac{2}{3} n - 11 \geqslant 17[/tex]

[tex]n \geqslant 42[/tex]

Explanation:

difference equals -

two-thirds equals 2/3

a number n equals variable of n

and 11 equals 11

at least equals _> (but like those together)

For solving equations just use photomath

The solution to the expression is n ≥ 42

An equation, statement of equality between two expressions consisting of variables and/or numbers

An equation is a mathematical expression that contains an equals symbol.

Equations often contain algebra.

Algebra is used in maths when you do not know the exact number in a calculation.

Translating the equation

[tex]\rm \dfrac{2}{3} \;n-11 \geq 17[/tex]

[tex]\rm \;n \geq (17 + 11)\times\dfrac{3}{2}\\\\\\ n \geq 42[/tex]

Therefore the solution to the expression is n ≥ 42

[tex] \frac{8836}{26} [/tex]

Step-by-step explanation:

thats the answer

The answer to the equation is Y or X.

2(2x + 3y) = 4x + 6y

Distrubitive property would be used on the right

4x + 6y = 4x + 6y

So, you could either subtractive 4x from both sides or 6x from both sides and be left with either one.

so your answer would be X or It could be Y.

Hello am greatly sorry for doing this but I needed to share this for clarification of the physics question.

Answer:

$2250

$2430

Step-by-step explanation:

If the seller made a profit of 20%, it means he sold the television at a price that is 20% higher than the cost price. That means that the sales price is 1.2 times higher than the cost price

let t = cost price of the television

the following equation can be derived

1.2 x t = $2700

divide both sides by 1.2

t = $2250

If there is a 10% discount, the television is (100 - 10%) 90% cheaper

0.9 x 2700 = $2430

The answer is 13 1/8ft3

Explanation:

Substitute into the formula:

= 7/2 x 5/2 x 3/2

= 105/8

= 13 1/8 ft3

Step-by-step explanation:

Given

See attachment for complete question

First, we calculate the water pipe length (AC):

[tex]AC^2 = AB^2 + BC^2[/tex]

[tex]AC^2 = 1^2 + x^2[/tex]

[tex]AC^2 = 1 + x^2[/tex]

[tex]AC = \sqrt{1 + x^2[/tex]

The cost of laying across water is twice (2 times) laying on land.

So, the total cost (C) is:

[tex]C = 2 * \sqrt{1 + x^2} + 1 * (4 - x)[/tex]

[tex]C = 2 \sqrt{1 + x^2} + (4 - x)[/tex]

Differentiate

[tex]C' = \frac{2x}{\sqrt{1 + x^2}} - 1[/tex]

To find the most economical cost, we simply minimize C' by equating C' to 0

[tex]C' = 0[/tex]

[tex]\frac{2x}{ \sqrt{1 + x^2}}-1 = 0\\[/tex]

[tex]\frac{2x}{ \sqrt{1 + x^2}}=1[/tex]

Cross multiply

[tex]2x= \sqrt{1 + x^2}[/tex]

Take square of both sides

[tex]4x^2 = 1+x^2[/tex]

Collect like terms

[tex]4x^2 -x^2= 1[/tex]

[tex]3x^2= 1[/tex]

Solve for [tex]x^2[/tex]

[tex]x^2 = \frac{1}{3}[/tex]

Solve for x

[tex]x = \sqrt{\frac{1}{3}}[/tex]

[tex]x = \frac{1}{\sqrt 3}[/tex]

Rationalize:

[tex]x = \frac{1}{\sqrt 3} * \frac{\sqrt 3}{\sqrt 3}[/tex]

[tex]x = \frac{\sqrt 3}{ 3}[/tex]

Answer:

[tex]5.976\times10^{24}[/tex]

Step-by-step explanation:

Standard form, also called scientific notation, is a more compact way of writing very big or very small numbers. All numbers in scientific notation have the form

[tex]m\times10^b[/tex]

where m is a number between 1 and 10, and b is an integer that represents how we've shifted the decimal point from the original number. For example, the number 23,000 in standard form would be written as 2.3 × 10⁴, since we have to shift the decimal point 4 places to the right to get back our original number.

We can turn 5,976,000,000,000,000,000,000,000 into a number between 1 and 10 by shifting the decimal 24 places to the left, giving us 5.976. We'll save that 24 as the exponent for our 10, giving us the final form

Answer:

1/9

Step-by-step explanation:

Answer:

Step-by-step explanation:

Please write this as y = (1/2)x^2 for greater clarity.  (1/2) is the coefficient of x^2 here.  

The applicable form for the equation of this quadratic is 4py = x^2.  

Your y = (1/2)x^2  becomes 2y = x^2.  Therefore, 4p = 2, or p = (1/2).

Thus, the focus is (0, 1/2) (just above the vertex, (0, 0) ), and the equation of the directrix is y = -1/2.

Answer: 1106.13 (2 decimal places)

Step-by-step explanation:

To work out the area of this composite shape you would have to put the two semi circles together to form a circle and work out the area of the circle (they have provided the radius which is 11in), then work out the area of the rectangle separately.

The formula for the area of a circle is πr^2 (pi x radius squared).

So when you put the numbers in the formula the area is πx11^2=380.1327111

Then to work out the area of the rectangle you would do base x height.

The height of the rectangle is the same as the diameter of the circle (the diameter is double the radius of a circle) which is 22in.

To find the area of the rectangle you do 22x33=726

So then to find the area of the whole shape you would have to add the area of the circle and the rectangle together.

726+380.1327111=1106.13 (2 decimal places).
