Answer:

1.5 OR 1 1/2

Step-by-step explanation:

Convert the fractions into decimals.

9/10 = 0.9

3/5 = 6/10 = 0.6

Divide the decimals.

0.9/0.6 = 1.5

Convert back to fraction.

1.5 = 1 1/2

Answer:

m = - 3

Step-by-step explanation:

[tex]\frac{m}{3} - \frac{2m}{5} = \frac{1}{5}[/tex]

It is much easier to work with whole numbers, compared to fractions, hence one should remove the denominator of the fraction. This can be done by multiplying by the LCM (least common multiple). In this case, it is fairly obvious that the LCM of 3 and 5 is 15. Therefore multiply the entire equation by 15.

[tex]15*\frac{m}{3} - 15*\frac{2m}{5}=15*\frac{1}{5}[/tex]

Simplify

[tex]5m-6m=3[/tex]

[tex]-m=3\\m=-3[/tex]

Answer:

y = 3x + 23

Step-by-step explanation:

Given the equation :

y - 8 = 3(x + 5)

We are to convert the equation to slope - intercept form:

Recall: general form of a slope - intercept model:

y = mx + c

Hence,

y - 8 = 3x + 15

y = 3x + 15 + 8

y = 3x + 23

Comparing :

y = mx + c

y = 3x + 23

Answer:

x=9

Step-by-step explanation:

-1+14x=12x+17

2x=18

x=9

Answer: x=9

Step-by-step explanation:

so the equation on top -1+14x= 125

and 12x+17= 125

Answer:

Step-by-step explanation:

If we define the line QR to be some variable of distance 'x', we can use the relationship of cosine to figure out the length of QR.

Remember, cosine is adjacent of the angle divided by the hypotenuse of the angle. So, if we take this x value over the longest side (hypotenuse), we get the value of cos(theta).

cos(25) = x/7

Multiply both sides by 7 to get:

7*cos(25) = x

Let your calculator do the work to get:

x = 6.3

Answer:

90

Step-by-step explanation:

a triangle's angles all add up to 180. take 51 and 39 away from 180 and you get 90

Answer: 90 degrees

Step-by-step explanation:

Theorem:

a+b+c=180 degrees

39 degrees + 51 degrees + x degrees = 180 degrees

39 + 51 = 90

180 - 90 = 90

Answer:

x=3

Step-by-step explanation:

5x+2=7x−4  

5x+2−7x=7x−4−7x

−2x+2=−4  

−2x+2−2=−4−2

−2x=−6

-2x/2=-6/2

x=3

Step-by-step explanation:

[tex] sum \: of \: interior \\ \: angels \: is  \: 2340 \:  degrees. \\

(n−2)⋅180=2340 \\

180n - 360=2340 \\ 180n = 2700 \\

n=15 \\

number \: of \: sides=15[/tex]

the polygon is 15 sided.

Answer:

Y=-4

Step-by-step explanation:

y = 3x + 2

y = 3(-2) + 2

y = -6 + 2

y = -4

Answer:

Y=5

Step-by-step explanation:

Y=2+3

So that why y is 5

Answer:

Step-by-step explanation:

20x100=2000

5x100=500

2000+500=2500

:)

Answer:

Step-by-step explanation:

Speed = Distance/Time

Time = Distance/Speed

Given

Distance = 1.2m = 0.012cm

Speed = 24.8cm/hr

Get the time;

Time = 0.012/24.8

Time = 4.84*10^-4hours

Hence it will take the water 4.84*10^-4hours to reach the top of the dock

Answer:

29.25 Interest

Step-by-step explanation:

Take the formula: I=PRT

The principal is 650.00, 4.5 is the rate, 1 year is the time, We do not know the interest.

Change the rate, 4.5 to 0.045 to help solve the problem.

Times 650.00, 0.045, and 1 together.

You will get 29.25, Which is the answer!

Booyah! You are done.

Hope this helps!

the answer is : a=9 and b=-1

Answer:  Piper will have $3750  

Step-by-step explanation:

In this situation we will represent the total amount she have in the bank by y and the number of weeks by x

The whole situation can be represented by the the equation

  y = 1400 + 50x  where y is the total amount , 1400 is the initial amount Piper deposited , 50 is of course the amount Piper will deposit each week , and x is the number of weeks.

Now since they are looking for the amount Piper will have in his account, you have to input 47 for x and solve for y.

y = 1400 + 50(47)

y = 1400 + 2350

y = 3750

Answer:

He has to run a total of 12 miles and has 3 more miles to run

Step-by-step explanation:

Well we know that 3/4 is 9 out of the total miles he is willing to run. We can divide 9 by 3 to get 1

Now we know 1/4 of his run is 3 miles

3*4= 12

He has to run a total of 12 miles and has 3 more miles to run

Answer:

He plans to run 12 miles

Step-by-step explanation:

He plans to run 12 miles because if he ran 9 miles so far and that is 3/4 of his way then you would do 3 divided by 9 to get 3.  Then you would add a 3 to nine because that 3 would be the last quarter t complete his run.
