Answer:

u=5

Step-by-step explanation:

5u+6-12u=-29

5u-12u+6=-29

-7u+6=-29

-7u=-29-6

-7u=-35

-7u/-7=-35/-7

u=-35/-7

u=5

Answer:

Step-by-step explanation:

5u - 12u + 6 = -29

-7u + 6 = -29

-7u = -35

u = 5

Answer:

5) x = -1

6) x = 2

Step-by-step explanation:

5) 5 + 2x + 6 = x + 10

   2x + 11 = x + 10

   2x + 1 = x

   1 = -x

   -1 = x

6) (9x + 7) + (-3x + 20) = 39

    6x + 27 = 39

    6x = 12

     x = 2

Answer:

For question 5, x= -1

Step-by-step explanation:

Segment Addition Postulate = ab+bc=ac

For Question 5,

(a)     +    (b)  = (c)  

5+2x  +   6    = x+10

5+2x+6=x+10

To solve that,

5+2x+6=x+10

Add 5+6

11+2x=x+10

Subtract 11 from both sides

2x= x-1

x-1=2x

Answer:

Step-by-step explanation:

[tex]2 + 1 = \frac{1}{2}x - x[/tex]

[tex]3 = - \frac{1}{2}x[/tex]

[tex]x = \frac{ - 3}{ \frac{1}{2} } \\ x = \frac{ - 6}{1} \\ x = - 6[/tex]

Answer: 40 percentage of his deliveries has Frank completed

Step-by-step explanation:

Given : Deliveries completed by Frank = 34

Total deliveries = 85

Percentage of deliveries has Frank completed = [tex]\frac{\text {Deliveries completed by Frank}}{\text {Total deliveries}}\times 100[/tex]

Putting in the values:

Percentage of deliveries has Frank completed = [tex]\frac{34}{85}\times 100=40\%[/tex]

Thus 40 percentage of his deliveries has Frank completed

Answer:

width=23.205 in.

length=29.085 in.

Step-by-step explanation:

width=x

length =x+5.88

Perimter=x+x+x=5.88+x+5.88=104.58

4x+11.76=104.58

4x=104.58-11.76

4x=92.82

x=23.205

width=x=23.205 In.

length=x+5.88=23.205+5.88=29.085 in.

Please let me know if you have any question

Answer:

mai is correct

Step-by-step explanation:

a quadrilateral with four congruent sides is never a regular polygon it is a rhombus. hope this helps!

A regular polygon has four congruent sides and four congruent angles.

I do not agree with any of them, because both arguments are incorrect

For a polygon to be a regular polygon, the following conditions must be met

Some quadrilaterals with four congruent sides are:

Rhombus, Kite, Square, etc.

A rhombus has four congruent sides, but all four angles are not congruent.

This means that Diego's argument is incorrect

All sides and angles of a square are congruent.

Because Mai says such polygons can never be a regular polygon, then Mai's argument is also wrong.

Hence, I do not agree with any of them.

Answer:

The percentage increase in A is 44%. The percentage increase in V is 72.8%.

Step-by-step explanation:

The easiest way to go about solving this problem is to pick your own numbers and plug them into the given equations.

For example, let's say that k = 5 and that r = 10.

[tex]A=kr^{2}[/tex]  ⇒ [tex]A= 5 * 10^{2} =500[/tex]

[tex]V=kr^{3}[/tex] ⇒ [tex]V= 5 * 10^{3}= 5000[/tex]

The question is asking, what is the percentage increase if r is increased by 20%. Our chosen k-value will stay the same but our r-value is going to increase. To find the new value of r, we multiply 10, our current value of r, by 1.2. This gives us a new value for r, which is 12.

[tex]10*1.2=12[/tex]

Now, we are going to plug in our new r-value and our k-value into the given equations. k = 5; new r = 12

[tex]A=kr^{2}[/tex] ⇒ [tex]A=5*12^{2}=720[/tex]

[tex]V=kr^{3}[/tex] ⇒ [tex]V=5*12^{3}=8640[/tex]

Next, we have to calculate the percentage increase in our values of A and V. To do this, we use the following formula:

[tex]Percentage Increase = \frac{final - initial}{initial} * 100[/tex]

Percentage Increase for A

Initial value: 500

Final Value: 720

[tex]Percentage Increase = \frac{720-500}{500} * 100 = 44%[/tex]

Percentage Increase for V

Initial value: 5000

Final Value: 8640

[tex]Percentage Increase= \frac{8640-5000}{5000} *100 = 72.8%[/tex]

The percentage increase for A is 44% and the percentage increase for V is 72.8%.

Hope this helps!

Answer:

An angle is considered a defined term in geometry because defined terms are terms that have a formal definition and can be defined using other geometrical terms.

Angle: Two rays that share the same endpoint, however, the rays take off in different directions. The area in the middle of the two rays is the angle measure.

Answer:

1/2 or 0.5

Step-by-step explanation:

PEMDAS (parentheses, exponents,multiplication, division, addition, subtraction)

Division: 18 divided by 12= 3/2 or 1.5

Answer:

x-int: (8/3, 0)

y-int: (0, -32/3)

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

x-intercept is the x-value when y = 0

y-intercept is the y-value when x = 0

Step 1: Write equation

2x - 1/3 = 1/2y + 5

Step 2: Subtract 5 on both sides

2x - 16/3 = 1/2y

Step 3: Multiply 2 on both sides

4x - 32/3 = y

Step 4: Rewrite

y = 4x - 32/3

Step 5: Find x-int

0 = 4x - 32/3

32/3 = 4x

x = 8/3

(8/3, 0)

Step 6: Find y-int

y = 4(0) - 32/3

y = 0 - 32/3

y = -32/3

(0, -32/3)

Answer:

PT=30 units

Step-by-step explanation:

Given that:

Line PQ which has a mid point at T.

[tex]PT = 3x + 9[/tex] and

[tex]TQ = 5x -5[/tex]

To find:

PT = ? in simplified terms.

Solution:

First of all, let us recall that mid point on a line segment is a point that divides the line in two equal parts.

In other words:

If a point B is the mid point of line segment AC, then AB = BC.

Here, the point T is the midpoint of PQ.

i.e. PT = TQ

[tex]3x+9=5x-5\\\Rightarrow 3x-5x=-5-9\\\Rightarrow -2x=-14\\\Rightarrow x=7[/tex]

Putting value of [tex]x[/tex] in PT above:

[tex]PT = 3x+9 = 3 \times 7 +9 \\\Rightarrow \bold{PT=30\ units}[/tex]
