Can someone help geometry

Answer:

Step-by-step explanation:

All the reasons are correct apart from the 4th.

Step 4 involves multiplication of both sides by (2/3). Thee reason given is: "Division property of equality", which is wrong as division is not applicable.

Answer:

Reason 4 is correct I just did the quiz

[tex]2\sqrt{3}[/tex]

------------------------

Steps:

1st write out equation

[tex]\frac{\sqrt{60}}{\sqrt{5}} \\[/tex]

Second write the conjugant and multiply it.

[tex]\frac{\sqrt{60}}{\sqrt{5}} * \frac{\sqrt{5} }{\sqrt{5} }[/tex]

After multiplying you should get,

[tex]\frac{10\sqrt{3}}{5}[/tex]

now after simplifying you should get

[tex]2\sqrt{3}[/tex]

Answer: x=-3

Step-by-step explanation:

2x-18=8x

-2x. -2x.

-18=6x

-18/6=6x/6

-3=x

Answer:

these both are the same equations

What the question???

Step-by-step explanation:

Woops did not mean to click add a answer

Answer:  1  1/2

You can write this as 1 & 1/2

The whole part is 1. The fractional part is 1/2

==========================================================

Explanation:

Let's say we had 18 cookies to hand out to 12 students.

How many cookies does each student get?

Using a calculator shows that 18/12 = 1.5 which means they get one whole cookie each

The leftovers is 18-12 = 6

Then notice how 6/12 = 1/2

So that's how the improper fraction 18/12 becomes the mixed number 1 & 1/2

So each student gets 1 full cookie, plus half a cookie.

------------------

Or we could do the problem like this

18/12 = (12+6)/12

18/12 = (12/12)+(6/12)

18/12 = 1 + (1/2)

18/12 = 1 & 1/2

Answer:

Train A = 70km

Train B = 75km

Train B is going faster than Train A.

Step-by-step explanation:

Train B = [tex] \frac{d}{t} = \frac{150}{2} = 75km[/tex]

Train A = [tex] \frac{d}{t} = 70km[/tex]

Answer:

p = -1.66

Step-by-step explanation:

-3p = p - 1 - (p - 6)

-3p = p - 1 - p + 6

-3p = 5

p = 5/-3

p = -1.66

Answer:

C. 64+4x=200

'X' is the price of the bracelet

Step-by-step explanation:

Ring: $64

4 Bracelet: 4 ( $x )

Total spend: $200=Ring+4 Bracelet

64+4x=200

4x=200-64

4x=136

x=136/4

x=34

Bracelet: $34

Step-by-step explanation:

there are (almost) no hidden tricks. the graphs are simply showing the answers.

#9

starts at 0 seconds and ends at 7 seconds.

starts at 0 meters and ends at 7 meters.

traveled 7 meters in 7 seconds.

#10

this is the only trap : please consider that the object did not move until 3 seconds into the chart. it remained steady for these first 3 seconds.

starts at 3 seconds and ends at 9 seconds.

starts at 1 meter and end at 5 meters.

traveled 5-1=4 meters in 9-3=6 seconds.

Answer:

Step-by-step explanation:

97+47+77 = 221

Answer:

$4.70 + $4.75m = $18.95 which is 3 miles in total.

Step-by-step explanation:

First make the numbers without the variables on one side.

4.75m = 18.95-4.70

Then subtract.

4.75m = 14.25

Finally divide the two numbers.

14.25 ÷ 4.75 = 3 miles

Answer:  m = 3  or 3 miles

Answer:

3 miles

Step-by-step explanation:

Pick up fee = $4.70

Charge = $4.75 per mile therefore this is expressed as 4.75 x m (or 4.75m)

18.95 = 4.7 + 4.75m (add the pick up fee plus fare per mile)

Subtract 4.7 from both sides then divide 4.75 from both sides.

This leaves you with m = 3

Answer:

Step-by-step explanation:

6)b) Sin A - x Cos A = 0

Sin A = x Cos A

[tex]\dfrac{Sin \ A}{Cos \ A} = x[/tex]

[tex]\dfrac{1}{x}=\dfrac{1}{\dfrac{Sin \ A }{Cos \ A}}=1*\dfrac{Cos \ A}{Sin \ A}=\dfrac{Cos \ A}{Sin \ A}[/tex]

[tex]RHS = x +\dfrac{1}{x}\\\\\\[/tex]

         [tex]= \dfrac{Sin \ A}{Cos \ A}+\dfrac{Cos \ A}{Sin \ A}\\\\\\=\dfrac{Sin \ A*Sin \ A}{Cos \ A*Sin \ A}+\dfrac{Cos \ A * Cos \ A}{Sin \ A* Cos \ A}\\\\\\= \dfrac{Sin^{2} \ A}{Cos \ A*Sin \ A}+\dfrac{Cos^{2} \ A}{Cos \ A* Sin \ A}\\\\= \dfrac{Sin^{2} \ A+Cos^{2} \ A}{Cos \ A*Sin \ A}\\\\=\dfrac{1}{Cos \A*Sin \ A}\\\\= \dfrac{1}{Cos \ A}*\dfrac{1}{Sin \ A}\\\\=Sec \ A * Cosec \ A[/tex]

          = LHS

7a) 1 - Sin A = 1/2

     [tex]1 = \dfrac{1}{2}+ Sin \ A\\\\1-\dfrac{1}{2}=Sin \ A\\\\\dfrac{1}{2}=Sin \ A\\[/tex]

⇒ A = 30°

Sec² A = Sec² 30° = [tex](\frac{2}{\sqrt{3}})^{2}=\frac{2^{2}}{(\sqrt{3)^{2}}}=\frac{4}{3}[/tex]

[tex]tan^{2} \ A = tan^{2} 30 = (\dfrac{1}{\sqrt{3}})^{2} = \dfrac{1}{3}[/tex]

LHS = 6 Sec² A + 9 tan² A

       [tex]= 6*\dfrac{4}{3}+9*\dfrac{1}{3}\\\\\\=2*4 + 3*1\\\\\\= 8 + 3\\\\= 11 = RHS[/tex]

Answer:

D

Step-by-step explanation:

|-13|=13

Answer:

For a line to be parallel it must have the same slope. So the slope of the new equation is 6.

The slope intercept form is y=mx+b. And we have a point (3,-5). Plug in what we know....

-5=6(3)+b

Solve for b (the y-intercept)

b= -23

Therefore.... y=6x-23

??? does that help????
