2(12 - y) = 23- (2y - 1) is there a solution for this?

Answers

Answer 1

Answer:

Step-by-step explanation:

Short Answer: No

2(12 - y) = 23- (2y - 1)                    Remove the Brackets on both sides

24 - 2y = 23 - 2y + 1                     Combine like terms on the right

24 - 2y = 24 - 2y                          No matter what you do, the 2ys are going to cancel. When they do, the question goes with them.

You get 24 = 24 Which is true but not relevant.

The other answer you could use is there are an infinite number of answers.

Equality will be maintained, but there is no single answer that works.

Answer 2

Answer:

This equation is an identity, all real numbers are solutions.

Step-by-step explanation:

Simplifying

2(12 + -1y) = 23 + -1(2y + -1)

(12 * 2 + -1y * 2) = 23 + -1(2y + -1)

(24 + -2y) = 23 + -1(2y + -1)

Reorder the terms:

24 + -2y = 23 + -1(-1 + 2y)

24 + -2y = 23 + (-1 * -1 + 2y * -1)

24 + -2y = 23 + (1 + -2y)

Combine like terms: 23 + 1 = 24

24 + -2y = 24 + -2y

Add '-24' to each side of the equation.

24 + -24 + -2y = 24 + -24 + -2y

Combine like terms: 24 + -24 = 0

0 + -2y = 24 + -24 + -2y

-2y = 24 + -24 + -2y

Combine like terms: 24 + -24 = 0

-2y = 0 + -2y

-2y = -2y

Add '2y' to each side of the equation.

-2y + 2y = -2y + 2y

Combine like terms: -2y + 2y = 0

0 = -2y + 2y

Combine like terms: -2y + 2y = 0

0 = 0

Solving

0 = 0

During a sprint, a basketball player is traveling at +3 m/s. Four seconds later, the player is traveling at –5 m/s. The average acceleration of the basketball player over the last 4 seconds is:

Answers

Answer:

the average acceleration of the basketball player over the last 4 seconds is 0.5 m/sec^2

Step-by-step explanation:

The computation of the average acceleration is shown below:

= Change in velocity ÷ change in time

= 5 - 3 ÷ 4

= 2 ÷ 4

= 0.5 m/sec ^2

Hence, the average acceleration of the basketball player over the last 4 seconds is 0.5 m/sec^2

Simplify. Your answer should contain only positive exponents.

Answers

Answer:

[tex]\frac{1}{4k^3}[/tex]

Step-by-step explanation:

It's already in a form that only ha positive exponents.  Just to state it though you could rewrite it as [tex]k*(4k^{4})^{-1}[/tex] or [tex]k*4^{-1}*k^{-4}[/tex]  The question asks for positive exponents though so yu don't need to do that.

You also need to know [tex]\frac{x^a}{x^b}=x^{a-b}[/tex] so in this case [tex]\frac{k}{k^4}=\frac{k^1}{k^4} =k^{1-4}=k^{-3}=\frac{1}{k^3}[/tex]

so [tex]\frac{k}{4k^4}=\frac{1}{4}*\frac{k}{k^4}=\frac{1}{4}*\frac{1}{k^3}=\frac{1}{4k^3}[/tex]

Obtain the greatest common factor of 18 and 24

Factors of 18 : 1 , 2, 3, 6, 9, 18

Factors of 24 : 1, 2, 3, 4, 6, 8, 12, 24

The greatest factor commo to both 18 and 24 is 6.

Hence, the greatest number of bouquet she could have is 6.

Need help FAST, 25 points. Calculate the value of x

Answers

Answer:

x = 106º

Step-by-step explanation:

The interior angles of a triangle add up to 180º.

First let's find the third interior angle.

We already have: 37º & 69º.

Add them together.

= 106º

To find our third angle, subtract this value from 180º.

180 - 106 = 74º

This is our third interior angle.

x and 74º are supplementary angles, meaning they add up to 180º. This is because they lie on the same straight line and are divided by a single line which they share.

To find x, subtract 74 from 180.

180 - 74 = 106

x = 106º

This is your answer.

Quarters have a coating of copper mixed with nickel on the outside. If the diameter of a quarter is 24.3 mm, then what is the surface area of one side of the quarter that will get coated?

Answers

Answer: 463.96 mm² or 46.4 cm²

Step-by-step explanation:

Quarters are circular in shape so the surface area of one side will be the area of a circle.

Area of a circle = π * r²

Radius = Diameter / 2

= 24.3 / 2

= 12.15 mm

Area = 22/7 * 12.15²

= 463.96 mm²
