Answer:
5x + 2 - 2(x - 1) = 3x + 4
⇔ 5x + 2 - 2x + 2 = 3x + 4
⇔ 3x + 4 = 3x + 4
⇔ 4 = 4

Two pieces of ribbon, one with a length of 63 inches and another with a length of 42 inches are cut into pieces of equal length without remainder. Find the greatest possible length that the pieces can be.
Answer
224 over 567
Step-by-step explanation:
Answer:
21
Step-by-step explanation:
the greatest possible length that the two ribbons would be when the ribbons are divided by their lowest common multiple.
The lowest common multiple of 63 is 3. 63/3 = 21
The lowest common multiple of 42 is 2 = 42/2 = 21

Let sin(2x)-sin(x)=0, where 0 ≤ x < 2pi. What are the possible solutions for x?
Step-by-step explanation:
sin2x - sinx = 0
2sinxcosx - sinx = 0
(Double Angle Formula)
sinx(2cosx - 1) = 0
Either sinx = 0 or cosx = 1/2.
When sinx = 0,
x = 0 or x = π.
When cosx = 1/2,
x = π/3 or x = 5π/3.
Hence the solutions are
x = 0, x = π/3, x = π or x = 5π/3.
f(x) = -x^2+10x - 17

Please Help!!! A bicycle has wheels 28 inches in diameter. tachometer determines that the wheels are rotating at 180 RPM (revolutions per minute). Find the speed the bicycle is traveling down the road.
Answer:
402.336 meters per minutes
Step-by-step explanation:
revolutions per minute = speed in meters per minute / circumference in meters.
Diameter = 28 inches
Circumference of the wheel = 2πr
r = Diameter/2 = 28/2 = 14
Circumference = 2 × π × 14
= 87.964594301 inches
Approximately = 88 inches
Note that:
1 inch = 0.0254 metre
88 inches = x
x = 88 × 0.0254 meters
x = 2.2352 meters
Hence:
Revolutions per minute = Speed in meters per minute / circumference in meters.
Speed = Revolutions per minute × circumference in meters.
Speed = 180 RPM × 2.2352 meters
Speed = 402.336 meters per minutes
Speed of the bicycle traveling down the road = 84π.
It is given that
Diameter of the wheel (2r) = 28 inches, where 'r' is the radius
Speed N(in revolutions per minute) = 180rpm
What is the formula for angular speed?Angular speed ω = [tex]\frac{2\pi N}{60}[/tex]radian per second.
[tex]w= \frac{2*\pi*180 }{60 } = 6\pi[/tex] radian per second
Speed of bicycle V = r*ω
Where,
r= radius of the wheel
[tex]V = 14*6*\pi = 84\pi inches/second[/tex]
Therefore,
speed of the bicycle traveling down the road = 84π.

Convert each radian measure into degrees.
4) 8pi/3
Answer:
[tex]\boxed {\boxed {\sf 480\textdegree}}[/tex]
Step-by-step explanation:
First, remember that π radians is equal to 180 degrees. Therefore, to convert from radians to degrees, multiply by 180/π.
The radian measure given is 8π/3
[tex]\frac {8 \pi}{3} * \frac{180}{\pi}[/tex]
Multiply the fractions. Multiply across the numerator, then across the denominator.
[tex]\frac{8 \pi *180}{3 * \pi}[/tex]
The pi in the numerator and denominator will cancel out.
[tex]\frac{8 *180}{3 }[/tex]
Multiply.
[tex]\frac{1440}{3}=480[/tex]
The radian measure 8π/3 is equal to 480 degrees.
The ratio of males to females at a party is 3 : 5
There are 12 more females than males.
How many people are at the party?
Answer:
48
Step-by-step explanation:
Given ratio of males to females at a party is 3 : 5.
Let the numbers of males and females be 3x and 5x respectively.
According to the given description:
No of females = No of males + 13
Therefore,
5x = 3x + 12
5x - 3x = 12
2x = 12
x = 12/2
x = 6
No of people at the party
= 3x + 5x
= 8x
= 8*6
= 48

Rewrite this expression using the distributive property.
(3x2 + 4x-7)(x-2)
Answer:
D
Step-by-step explanation:
Each factor on the right has to be multiplied by the equation on the left and then you add them.
The expression (3x² + 4x - 7) ( x- 2) can be rewritten as 3x³- 2x²- 15x + 14.
To rewrite the expression (3x² + 4x - 7) ( x- 2) using the distributive property, we need to distribute each term in the first polynomial to each term in the alternate polynomial.
(3x² + 4x - 7) ( x- 2)
= 3x²( x- 2) + 4x( x- 2)- 7( x- 2)
Now, distribute each term
= 3x³- 6x²+ 4x²- 8x- 7x + 14
Combine like terms
= 3x³- 2x²- 15x + 14
Thus, using the distributive property, the expression (3x² + 4x - 7) ( x- 2) can be rewritten as 3x³- 2x²- 15x + 14.

The sum of two numbers is 10. Their difference is 6. What are the two numbers?
Answer: 8 and 2
Step-by-step explanation:
this is simple, since we only have 10 numbers to work with. i just kept experimenting with numbers until i got one that had a difference of 6. no strategy, just brain power. hope this helps! xoxo
Answer:
So negatove numbers are gonna be impossible becuase we know that the highest we can go is -10+20=10 but it’ll give a whole different difference when subtracted.
And it can’t be greater then 10 becuase if you do add them it won’t be 10
SO it has to be between 1-10
So what equals 10?
5/5
2/8
8/2
6/4
4/6
3/7
7/3
Now 5 and 5 is out cause if subtracted its 0
2/8 and 8/2 works, if added you get 10 but when subtracked the way for 8/2 from left to write it’ll give 6 which is the only one which will give.
final answer the two numbers are 8 and 2
