What value of x makes the equation true?
Answer:
B.2.5
Step-by-step explanation:
The equation would be
[tex]-4x +8 = 2x -7[/tex]
I believe that you would know how to solve this.
You could also sub in 2.5 for the x to check.
Good Luck!!!!!
simplify the equation -x^3 + 5x + 7x^2 +8x^3 - (-x^3 +x)
Answer:
8x³ + 6x² + 5x
Step-by-step explanation:
Let's simplify step-by-step.
−x^3 + 5x + 7x^2 + 8x^3 − ( −x^3 + x )
Distribute the Negative Sign:
= −x^3 + 5x + 7x^2 + 8x^3 + −1 ( −x^3 + x )
= −x^3 + 5x + 7x^2 + 8x^3 + −1 ( −x^3 ) + −1x
= −x^3 + 5x + 7x^2 + 8x^3 + x^3 + −x
Combine Like Terms:
= −x^3 + 5x + 7x^2 + 8x^3 + x^3 + −x
= ( −x^3 + 8x^3 + x^3 ) + ( 7x^2 ) + ( 5x + −x )
= 8x^3 + 7x^2 + 4x
Answer:
= 8x^3 + 7x^2 + 4x

4. [tex]\frac{100 l}{40 w}[/tex], [tex]\frac{25}{10}[/tex], [tex]\frac{50}{20}[/tex]
5. [tex]\frac{2 hrs}{120 m}[/tex], unit rate= 60 miles per hour, [tex]\sqrt[2]{120}[/tex]=60
6. [tex]\sqrt[3]{900}[/tex]= 300, 300x3=900, unite rate= 300km per hour
7. [tex]\frac{50}{5}[/tex]=[tex]\frac{10\\}{1}[/tex], unit rate for Tim= $10 for 1 hour, [tex]\frac{24}{2}[/tex]=[tex]\frac{12}{1}[/tex], unit rate for Jane= $12 for 1 hour, Jane has the higher rate of pay.
8. [tex]\frac{65}{4}[/tex]=[tex]\frac{16.25}{1}[/tex] , [tex]\sqrt[4]{65}[/tex]= 16.25, unit rate for Jon is 16.25ths of a pushup per minute.
[tex]\frac{45}{3}[/tex]=[tex]\frac{15}{1}[/tex], [tex]\sqrt[3]{45}[/tex]=15, unit rate for Paul is 15 pushups per minute.
Jon can do more pushups in 1 minute

Find the ratio of the volume of the triangular prism
to the volume of the cuboid,
Give your answer in its simplest form
고
Answer:
The ratio of the volume of the triangular prism to the volume of the cuboid is [tex]\frac{3}{20}[/tex].
Step-by-step explanation:
Geometrically speaking, the volume of the prism is equal to the product of the area of the base and its height. Then, the volumes of the triangular prism and the cuboid are, respectively:
Triangular prism
[tex]V_{tp} = \frac{1}{2}\times 5\,cm \times 4\,cm \times 9\,cm[/tex]
[tex]V_{tp} = 90\,cm^{3}[/tex]
Cuboid
[tex]V_{c} = 6\,cm\times 5\,cm \times 20\,cm[/tex]
[tex]V_{c} = 600\,cm^{3}[/tex]
Lastly, the ratio of the volume of the triangular prism to the volume of the cuboid is:
[tex]r = \frac{V_{tp}}{V_{c}}[/tex]
[tex]r = \frac{3}{20}[/tex]
The ratio of the volume of the triangular prism to the volume of the cuboid is [tex]\frac{3}{20}[/tex].

Answer:
C. In y^2-y=6, 6 should have been subtracted on both sides first.
Step-by-step explanation:
It is a quadratic equation so you subtract the 6 and create
y^2-y-6=0
Then you factor it to:
(y-3)(y+2)=0
The solutions then are:
y-3=0, y=3 and y+2=0, y=-2
