Answer:

x has no solution

Step-by-step explanation:

2x+4-7=6x-4-4x

2x-3=2x-4

-3=-4

Answer:

No solution

Step-by-step explanation:

2(x+2) -7 = 6x - 4(1+x)                  (Distribute 1st)

2x + 4 - 7 = 6x - 4 - 4x

2x - 3 = 2x - 4                         (Combine like-terms)

2x - 2x = -4 + 3

0 = -1

No solution

Step-by-step explanation: 5/1 multiplied by 7/10 equals 35/10.  After simplifying it is 3.5 inches squared.

Answer:

The value of x in this equation is 3/2.

Step-by-step explanation:

First, let's take the original equation:

2 + 5x - 2x = 6x + 3x - 7

In order to solve for x, we must isolate the variable x on one side of the equation, and the rest of the numbers on the other side of the equation. So we take: 2 + 5x - 2x = 6x + 3x - 7 and use some of the properties of equality:

We start with 2 + 5x - 2x = 6x + 3x - 7 and see that we can minus 2 on both sides of the equation as highlighted below:

2 + 5x - 2x = 6x + 3x - 7

2 + 5x - 2x - 2 = 6x + 3x - 7 - 2

This simplifies the equation to 5x - 2x = 6x + 3x - 9.

Remember, we can arrange the equation like this along as we do on one side what we do on the other. Now, we have 5x - 2x = 6x + 3x - 9, and see that the rest of 6x and 3x needs to go on the left side of the equation. In order to do this, we can minus 6x from both sides of the equation as shown below:

5x - 2x = 6x + 3x - 9

5x - 2x - 6x = 6x + 3x - 9 - 6x

which then simplifies to 5x - 2x - 6x = 3x - 9. Now we can do the same thing by minus 3x from both sides of the equation.

5x - 2x - 6x = 3x - 9

5x - 2x - 6x - 3x = 3x - 9 - 3x

5x - 2x - 6x - 3x = -9

Now, we must simplify the left side of this equation by adding together the variable numbers 5x - 2x - 6x - 3x. This is shown below:

5x - 2x - 6x - 3x = -9

3x - 6x - 3x = -9

-6x = -9

Lastly, we can divide the number -9 by -6 to get the answer of what 1 x equals. This means -9/-6 = 3/2.

X is indeed equal to 3/2

Answer:

36degrees

Step-by-step explanation:

If m<A and m<B are vertical angles, hence m<A = m<B (vertical angles are equal)

Given the following

m<A = (2x+26)°

m<B = (3x+21)°

Equating both expressions

2x + 26 = 3x + 21

2x - 3x = 21 - 26

-x = -5

x = 5

Get the measure of m<B

m<B = (3x+21)°

m<B = 3(5) + 21

m<B = 15+21

m<B = 36degrees

Hence the measure of angle B is 36degrees

Answer:

3.5 cubic units

Step-by-step explanation:

First, find the volume of one cube

Use the cube volume formula, V = s³, where s is the side length

V = (1/2)³

V = 1/8 cubic units

Now, find the volume of the prism by multiplying this by 28, since there are 28 cubes

28(1/8)

= 3.5

So, the volume of the prism is 3.5 cubic units

Answer:

y = (25/4)(x + 5)^2

Step-by-step explanation:

1.  Interchange x and y, obtaining:  x = -5 + (2/5)√y

2.  Solve this result for y:  x + 5 = (2/5)√y

    Squaring both sides, we get (x + 5)^2 = (4/25)y

     Multiplying both sides by (25/5) cancels out the (4/25) coefficient:

      y = (25/4)(x + 5)^2       This is the inverse of the given function.

the solutin and the answer rate pls i

2x2=4

4x24=100  

Answer:

7.74 minutes

Step-by-step explanation:

Scott's rate = 20 /16 = 1.25

Ashley's rate = 20 / 15 = 1.333

Combined rate = (1.25 + 1.3333) = 2.583333

Hence, time it will take to inflate 20 balloons :

Rate = number of balloons / time taken

2.583333 = 20 / time taken

Time taken = 20 / 2.583333

Time taken = 7.7419

It will take them approximately 7.7 minutes to inflate 20 balloons

Answer:

2/3 pound of dough is left

Step-by-step explanation:

Amount of dough available = 6 pounds

The amount used in making sandwich rolls = 8/9 of the total amount

= [tex]\frac{8}{9} \times6 = 5\frac{1}{3} pounds[/tex]

Therefore, amount of dough left over [tex]= 6- 5\frac{1}{3} = \frac{2}{3} \\[/tex]

Hence, 2/3 pounds of dough is left

Answer:

209.43951 round to the nearest tenth is 209.44

Step-by-step explanation:

A cone with a base radius of 5 units and a height of 8 units has a volume of 209.44 cubed units.

If a cone has a flat bottom, meaning the height and radius meet at right angles, then this formula can be used to find of volume ('V') of that cone (also know as a right circular cone):

V = 1/3(PI*r squared * h )

The volume of a cone can be calculated by taking one-third of the result of the radius squared, multiplied by the height, multiplied by the mathematical constant pi.

Here is a step-by-step case that illustrates how to find to volume of a cone with a radius of 2 feet and a height of 3 feet. Note that in order to save space (and because pi cannot be determine precisely) a limited number of decimal places are used, the symbol ~ denotes that this answer is an approximation.

V = 1/3(pi * r^2 * h)

= 1/3(pi * 2^2 * 3)

= 1/3(pi * 12)

= 1/3(37.7)

~ 12.6 cubic feet

Answer:

See Explanation

Step-by-step explanation:

Given

[tex]0 \le a \le 1[/tex]

[tex]8*a =b[/tex]

Required

Determine the true statement about b

The question is incomplete as options are not given. However, a general explanation is as follows:

Rewrite [tex]8*a =b[/tex]

[tex]b = 8 * a[/tex]

When a = 0

[tex]b = 8 * 0 = 0[/tex]

When a = 1

[tex]b = 8 * 1 = 8[/tex]

This means that:

For [tex]0 \le a \le 1[/tex]

Then [tex]0 \le b \le 8[/tex]

This means that: b is a number between 0 and 8

Answer:

7pi/theta = radius

Step-by-step explanation:

So we are using the arc length, central angle(in radians), and radius.

We know arc length, which is 7pi.

We don't know theta, which does not matter.

And finally, we don;t know radius, which is what we are looking for.

To find radius, we use:

arc length/theta=radius

Lets plug in our values:

7pi/theta=radius.

So the answer to the khan acadamy question is

7pi/∅

Here are some othr things that may help:

Radian * Radius = arc length

This solves for arc length

Here is another one:

Arc length/radius= radian

This solves for radians

Answer:

Step-by-step explanation:

The common difference is 3.

nth term = -6+(n-1)3

-6+(n-1)3 = 162

(n-1)3 = 168

n-1 = 56

n = 57

162 is the 57th term.

S₅₇ = 57×(a_1+a_{57})/2

= 57×(-6+162)/2

= 57×156/2

= 57×78

= 57×(-6+162)/2

= 4446
