seven less than four times a number equals 13. What is the number. Ok

Answer:

B. Quadrilateral

It's a quadrilateral because a quadrilateral is a polygon that has four sides and all the images has four sides

Given:

The expression is

[tex]7x^3+5x+4x^5+2x^3[/tex]

To find:

The simplified form of given expression.

Solution:

We have,

[tex]7x^3+5x+4x^5+2x^3[/tex]

On combining like terms, we get

[tex]=(7x^3+2x^3)+5x+4x^5[/tex]

[tex]=9x^3+5x+4x^5[/tex]

Arranging the terms according to their degrees, we get

[tex]=4x^5+9x^3+5x[/tex]

Therefore, the simplified form of the given expression is [tex]4x^5+9x^3+5x[/tex].

R = 200 [tex]\frac{200000x 1011^{-20} -200000x1000x^{20} }{11 x 1011x^{2o} }[/tex]

Answer:

We conclude that the distance between two cities on a map = 6 inches.

Step-by-step explanation:

Given

Map scale:

1 in = 50 miles

Thus, in order to determine the distance in inches between two cities on a map, all we need is to divide the original distance between two cities i.e. 250 miles by 50 miles as 1 in = 50 miles.

so

Thus, we conclude that the distance between two cities on a map = 6 inches.

Answer:

a9=13122

Step-by-step explanation:an=a1rn−1

Substitute in the values of

a1=2 and r=3

an=(2)⋅(3)n−1

Remove parentheses.

an=2⋅3n−1

Substitute in the value of n to find the 9th term.

a9=2⋅3(9)−1

Subtract

1 from 9

a9=2⋅38

Raise 3 to the power of 8.

a9=2⋅6561

Multiply

2 by 6561.

a9=13122

Answer: 9 cm = LEngth

Step-by-step explanation:

27/3 = L

9 = LEngth

Answer:

The length is 9cm

Step-by-step explanation:

Formula = A = l * w

We have the width which is 3

And we have the area which is 27

All we need to do is work backward

A = l * w

27 = l * 3

27/3 = l * 3/3

9 = l

The length of the rectangle is 9

We can use that to check our work and see if its correct

Check

A = l * w

A = 9 * 3

A = 27 CORRECT

Now we know it's correct

Hope this helped!

Answer:

CB is 8.8 ⇒ D

Step-by-step explanation:

In any triangle, the line segment joining the mid-points of two sides is parallel to the 3rd side and equal to half its length

In the given figure

∵ ABC is a triangle

∵ E and D are the midpoints of sides AC and AB

∵ CB is the 3rd side

→ By using the rule above

∴ ED // CB

∴ ED = [tex]\frac{1}{2}[/tex] CB

∵ ED = x + 0.7

∵ CB = 3x - 2.3

→ Substitute them in the equation above

∴ x + 0.7 =  [tex]\frac{1}{2}[/tex] (3x - 2.3)

∴ x + 0.7 =  [tex]\frac{1}{2}[/tex] (3x) -  [tex]\frac{1}{2}[/tex] (2.3)

∴ x + 0.7 = 1.5x - 1.15

→ Subtract 1.5x from both sides

∵ x - 1.5x + 0.7 = 1.5x - 1.5x -1.15

∴ -0.5x + 0.7 = -1.15

→ Subtract 0.7 from both sides

∵ -0.5x + 0.7 - 0.7 = -1.15 - 0.7

∴ -0.5x = -1.85

→ Divide both sides by -0.5

∴ x = 3.7

→ Substitute x by 3.7 in the expression of CB

∵ CB = 3(3.7) - 2.3

∴ CB = 11.1 - 2.3

∴ CB = 8.8

So first, you know that 4 dozen doughnuts = 48 doughnuts. Next, to find how much you could get for one dollar you have the ratio $24:48 doughnuts and you can divide both sides of this ratio by 24 to get $1:2 doughnuts.

Answer:

Step-by-step explanation:

So first let us break how much trinkets one worker can make and find out the time frame. So the first two workers each can make a trinket in 90 seconds, 90/2 is 45 (seconds) for 1 worker. And the third worker takes 10 seconds longer, so 45+10 is 55 seconds for the third worker to make 1 trinket. There are 60 minutes in a hour, 60x60(seconds) is 3600 seconds in an hour. But here we will have to do 3600/100, because we forget about the individual time and focus on the combined time. So we add 10 more to 90, and now get 3600/100, which gives us out result of 36 trinkets made in an hour

Equation is formed when two equal expressions are equated together with the help of an equal sign. The value of x is 7.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The equation that is given to us is  -4x – 10 = -38, now in order to solve the equation, we will add 10 on both sides to isolate x terms, and then divide both the sides by (-4), to get the value of x.

[tex]-4x - 10 = -38\\\\-4x -10+10 = -38 +10\\\\-4x = -28\\\\\dfrac{-4x}{-4} = \dfrac{-28}{-4}\\\\x = 7[/tex]

Hence, the value of x is 7.

Answer:

41 units

Step-by-step explanation:

The Pythagorean  Theorem is given by :

[tex]a^2+b^2=c^2[/tex]

In a right ΔABC, AB = 40, BC = 9, & AC = x (AC is the hypotenuse)

Using the above theorem,
