Find The LCD That would eliminate the fractions
Answer:
[tex]x=\frac{7}{15}[/tex]
Step-by-step explanation:
[tex]5x-\frac{1}{5} =\frac{7}{3}[/tex]
[tex]5x - \frac{3}{15} = \frac{35}{15}[/tex]
[tex]5x - \frac{3}{15} + \frac{3}{15} = \frac{35}{15} + \frac{3}{15}[/tex]
[tex]5x=\frac{35}{15}[/tex]
[tex]\frac{5x}{5} } =\frac{\frac{35}{15}}{5}[/tex]
[tex]x=\frac{7}{15}[/tex]

HELP ASAP WILL AWARD BRAINLIEST ! find the product of the binomials f(x) and g(x). write your answer in standard form
Answer:
y=x^2 -5x+4
Step-by-step explanation:
F(x)= -x+1
G(x)-x+4
(-x+1)(-x+4) = x^2 -4x-1x+4 = x^2-5x+4
=======================================================
Explanation:
The f(x) function goes through (0,1) and (1,0). It's slope is
m = (y2-y1)/(x2-x1)
m = (0-1)/(1-0)
m = -1
The y intercept is b = 1 because this is where the blue line crosses the y axis.
We go from y = mx+b to y = -1x+1, or simply y = -x+1.
So f(x) = -x+1
Through similar steps, you should find that g(x) = -x+4
Both f(x) and g(x) have the same slope, which makes them parallel lines.
-----------------------------------
Once we know what f(x) and g(x) are, we multiply them out like so:
f(x) * g(x) = ( f(x) ) * ( g(x) )
f(x) * g(x) = ( -x+1 ) * ( -x+4 )
f(x) * g(x) = w(-x+4) ..... let w = -x+1
f(x) * g(x) = -xw + 4w ... distribute
f(x) * g(x) = -x( w ) + 4( w )
f(x) * g(x) = -x( -x+1 ) + 4( -x+1 ) ... plug in w = -x+1
f(x) * g(x) = x^2 - x - 4x + 4 ... distribute twice more
f(x) * g(x) = x^2 - 5x + 4
You could use the FOIL rule or box method as alternative routes to get this answer. I prefer the box method because the FOIL rule is only limited to multiplying binomials, while the box method allows you to multiply two polynomials of any length.
Determine whether the sequence is arithmetic or geometric.
Sequence 1: 32, 16, 0, –16, ...
Sequence 2: 32, 16, 8, 4, ...
Which of the following statements are true regarding Sequence 1 and Sequence 2.
Answer:
Sequence 1 is arithmetic, sequence 2 is geometric.
Step-by-step explanation:
Sequence 1 is being subtracted by 16 each time, so it is arithmetic.
Sequence 2 is being divided by 2 each time, so it is geometric.
Both, sequence 1 and 2, have terms 32 and 16.

Answer:
a) 84π b) 109.2π
Step-by-step explanation:
The formula to find this is v=πr^2h/3
r=d/2. so the radius (r) is 6 because you have to divide the diameter (12) by 2. and the height is 7. so, 6^2=36 and 36x7=252.
252/3=84
and because the question is asking for the EXACT value, you need to just put the pi symbol next to it. Final answer for a is 84π
B) you need to find 30% of 84, which is 25.2 and add it to 84, and you will get 109.2! Final answer is 109.2π.

Answer:
The answer should be 10c - 4d
Step-by-step explanation:
3c + 7c - 9d + 5d = 10c - 4d
Step-by-step explanation:
First you add up 3c and 7c as they have the same parameter. That makes 10c. Then calculate 5d-9d which equals -4d. You can change the order of 5d-9d in a way that you would reduce the larger number from the smaller number so that you could calculate it easily like that. The final Ander 2ould be 10c-4d
What is the difference between a 30° angle and a -30° angle?
Please provide a complete sentence or two.
Answer:
See below
Step-by-step explanation:
A 30° angle is measured 30° counterclockwise while a -30° angle is measured 30° clockwise. Therefore, you can say -30°=360-30°=330° because 30° is a reference angle located in Quadrant IV.

Solve for x
Please help me with this
Answer:
hope this helps you look it once.
Answer:
x = 16, x = 17
Step-by-step explanation:
Given a line parallel to a side of a triangle and it intersects the other 2 sides, then it divides those sides proportionally, that is
[tex]\frac{x+8}{20}[/tex] = [tex]\frac{2x-5}{22.5}[/tex] ( cross- multiply )
20(2x - 5) = 22.5(x + 8)
40x - 100 = 22.5x + 180 ( subtract 22.5x from both sides )
17.5x - 100 = 180 ( add 100 to both sides )
17.5x = 280 ( divide both sides by 17.5 )
x = 16
----------------------------------------------------------------
[tex]\frac{2x+8}{28}[/tex] = [tex]\frac{5x-4}{82-28}[/tex] = [tex]\frac{5x-4}{54}[/tex] ( cross- multiply )
28(5x - 4) = 54(2x + 8)
140x - 112 = 108x + 432 ( subtract 108x from both sides )
32x - 112 = 432 ( add 112 to both sides )
32x = 544 ( divide both sides by 32 )
x = 17

The density of pure iron is 7.874 g/cm3 . A piece of steel made of pure iron and other types of iron is in the shape of a rectangular pyramid. The rectangular pyramid has a base edge length of 4 cm , a base edge width of 9 cm , a height of 5 cm , and a mass of 425 g . What is the difference between the density of pure iron and the density of the steel rectangular pyramid? Round your answer to the nearest thousandth.
Answer:
"5.5129 g/cm³" is the appropriate solution.
Step-by-step explanation:
According to the question, the values are:
Iron's density,
= 7.874 g/cm³
Base edge length,
= 4 cm
Base edge width,
= 9 cm
Height,
= 5 cm
Mass,
= 425 g
As we know,
The Density of rectangular pyramid will be:
= [tex]\frac{Mass}{Volume}[/tex]
or,
= [tex]\frac{Mass}{Length\times Width\times height}[/tex]
On putting all the given values, we get
= [tex]\frac{425}{4\times 9\times 5}[/tex]
= [tex]\frac{425}{180}[/tex]
= [tex]2.3611 \ g/cm^3[/tex]
hence,
The difference will be:
= [tex]7.874-2.3611[/tex]
= [tex]5.5129 \ g/cm^3[/tex]

Which angle is coterminal with a 110° angle?
O A. An angle measuring 460°
O B. An angle measuring -110°
C. An angle measuring 290°
O D. An angle measuring 470°
Answer:
D. An angle measuring 470*
Step-by-step explanation:In this question
The coterminal angle for 110° is 470°.
What are coterminal angles?"Coterminal angles are two (or more) angles that have their initial and terminal sides in the same positions. However, the angle measures differ either because one angle is measured clockwise and the other is measured counterclockwise".
For the given situation,
The angle is 110°.
The coterminal angles can be determined by adding or subtracting 360° to the given angle.
For 110° = [tex]360+110[/tex]
⇒ [tex]470[/tex]°
Hence we can conclude that the coterminal angle for 110° is 470°.

I need help with this problem.
Answer:
[tex]x=6,\\m\angle 1=18^{\circ}[/tex]
Step-by-step explanation:
Since the problem denotes the figure as a parallelogram, [tex]\overline{AB}[/tex] is parallel to [tex]\overline{DC}[/tex]. Therefore, angles 1 and 2 are equal (from corresponding angles and vertical angles).
Therefore, we have the following equation:
[tex]m\angle 1=m\angle 2,\\x+12=6x-18,\\30=5x,\\x=\boxed{6}[/tex]
Substituting [tex]x=6[/tex]:
[tex]m\angle 1=x+12=6+12=\boxed{18^{\circ}}[/tex]

c = 22.3 km
Step-by-step explanation:
You can solve this problem using cosine law:
[tex] {c}^{2} = {a}^{2} + {b}^{2} - 2ab \cos( \gamma ) [/tex]
where a and b are the legs of the triangle, c is the unknown length and the angle gamma is the angle opposite length c. We know that
a = 50 km
b= 52.4 km
gamma = 25°
c^2 = (50 km)^2 + (52.4 km)^2 -2(50)(52.4)cos25°
= 496.707 km^2
or
c = 22.3 km
