The work of a student to solve the equation 3(2x − 4) = 8 + 2x + 6 is shown below: Step 1: 3(2x − 4) = 8 + 2x + 6 Step 2: 5x − 7 = 14 + 2x Step 3: 5x − 2x = 14 + 7 Step 4: 3x = 21 Step 5: x = 7 In which step did the student first make an error and what is the correct step? (5 points) Group of answer choices Step 3; 5x + 2x = 14 + 7 Step 3; 5x − 2x = 14 − 7 Step 2; 6x − 12 = 14 + 2x Step 2; 6x − 7 = 2(6 + x + 4)

Answers

Answer 1
The answer was actually posted on another one but it should be step 2; 6x - 12 = 14 + 2x. Or you can search the question again on here and you should find it!

Answers

Answer:

Sam is 15 years old and Ram is 35.

in five years Sam will be 20 and Ram will be 40, which is twice as old in age.

Sam=x Ram=x+20 in 5 years they will be Sam=x+5. Ram=x+20+5=x+25 also Ram will be twice old as sam so Ram=2Sam. X+25=2(x+5). X+25=2x+10. X=15 so sam will be 15 years old and Ram 2•15=30

The radius of the hemisphere is 16 mm

length of the inclined sides are 20 mm

The perimeter of the figure is the sum of the length of two inclined sides and a semi-circle circumference

[tex]\Rightarrow \text{Perimeter P=}\dfrac{2\pi r}{2}+2\times 20\\\\\Rightarrow P=\pi \times 16+40\\\Rightarrow P=50.75+40\\\Rightarrow P=90.75\ mm[/tex]

What is the diameter of a cone with height 8 m and volume 150 pi m3 ?
A. 7.5 m
B. 5V3 m
o C. 7.573 m
D. 15 m

Answers

Answer:

V = pi*r^2*h

V = 150 m^3

h = 8 m

150 = pi*r^2*8

Solve for r (the radius) then multiply by 2 to obtain the diameter.Only, this is a cone, not a cylinder.

V = 1/3 pi r^2 h

Diameter of the cone is 15 m. So, option D is correct.

What is meant by solid shape ?

Solid shapes are defined as the three-dimensional objects that are described by the three dimensions length, breadth and height.

Here,

Volume of the cone is given by,

 V = 150[tex]\pi[/tex] m³

Height of the cone, h = 8 m

We know, the equation for the volume of a cone is,

V = 1/3[tex]\pi[/tex]r²h

where r is the radius and h is the height of the cone.

So,

(1/3) [tex]\pi[/tex]r²h = 150[tex]\pi[/tex]

r²x 8 = 3 x 150 = 450

r² = 450/8

r² = 56.25

r = 7.5 m

Therefore, diameter of the cone,

d = 2r

d = 2 x 7.5

d = 15 m

Hence,

Diameter of the cone is 15 m.

Answers

Answer:

Opción b, P(2) = 0

Step-by-step explanation:

Tenemos la expresión:

P(y) = y^2 - 7*y + 10

Para encontrar el valor P(2), simplemente debemos remplazar todas las "y" en la expresión de arriba por el valor 2, asi obtenemos:

P(2) = 2^2 - 7*2 + 10 = 4 - 14 + 10 = (4 - 14) + 10 = -10 + 10 = 0

P(2) = 0

La opción correcta es b.

|Calculate the midpoint (-5,5), K(-3,-2)

Answers

Answer:

(-4,1.5)

Step-by-step explanation:

Given :-

Two points (-5,5) and (-3,-2)

And we need to find out the midpoint of the two points. The midpoint of two points is given by the ,

[tex]:\implies[/tex] Midpoint =( x1+x2/2 , y1+y2/2)

[tex]:\implies[/tex] Midpoint =( -5-3/2 , 5-2/2)

[tex]:\implies[/tex] Midpoint =(-8/2,3/2)

[tex]:\implies[/tex] Midpoint = (-4 , 1.5)

Hence the midpoint of the two points is (-4,1.5) .
Explaination :

Here we would be using the midpoint formula to find the co-ordinates of the line segment joining the two given points.

Given points,

(-5,5) and (-3,-2)
