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:
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
Work out the area of this trapezium. 4cm 13cm 5cm 19cm pls help you be brainliest
Answer:
This is your answer ☺️☺️☺️
here is a formula:
a=2b-c
what is the value of a if b=12 and c=-4
Answer:
a=28
Step-by-step explanation:
a = 2b - c
a = 2(12) - (-4)
a = 24 + 4
a = 28
by the formula
a=2b-c
if b =12
so, a= 2*12-(-4)
a= 24+4
a=28

Need help FAST, 25 points. Calculate the value of x
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.
Hope this helps!

−9x−6y=15
9x−10y=145
y=
x=
Answer:
Step-by-step explanation:
Adding the two equations together gives you
9x-10y-9x-6y=145+15
-16y=160
y=-10, using this value in 9x-10y=145 gives you
9x-10(-10)=145
9x+100=145
9x=45
x=5
So y=-10 and x=5

Sara picked 18 to 24 roses she divided flowers into groups so that the same number of tulips and roses were in each bouquet. What is the greatest number of bouquets she could have
Answer:
6 bouquet
Step-by-step explanation:
To obtain the greatest number of bouquet she could have ;
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.

Whats the equation to find the total cost ?
you will explain how to go about solving for the unknown letters A B C D using your angle vocabulary /concepts. Organize your sentences in a way that clearly emphasis your understanding of this unit.
Angle vocabulary/ concepts :
Supplementary Angle
Transverse Angles
Complimentary Angle
Triangle Sum Theorem
Right Angle
Straight Angle
Vertical Angel
Congruent
Parallel Lines
Answer:
To find c° go with Triangle Sum Theorem .
To find d° go with Supplementary Angle with 58°.
To find a° go with Transverse Angles.
To find b° go with Transverse Angles .
Step-by-step explanation:
c° = 180- 58 - 48 = 74°
b° = 48°
d° = 180 - 58 = 122°
a° = 58°
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:
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.
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]

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?
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
