Step-by-step explanation:

Divide 26.25 by 5 and there's your answer.

Answer:

x=13

Step-by-step explanation:

Well, the triangle is always equal to 180 degrees in total. Lets remember that x will always be the same in every equation.

So, (5x-11) x (2x+20) x (11x-63) = 180.

Now, take away the parenthesis and add up all the like terms.

This should = 18x-54 = 180.

Now solve like you regularly would. Add 54 on both sides which equals,

18x=234. Now, divide 18 on both sides.

x = 13.

Hope this helps.

Answer:

y=3, x=-1

Step-by-step explanation:

(2x+3y)-(2x-y)=7-(-5)

4y=12

y=3

2x+3y=7

2x=7-9

x=-1

Answer:

u both got rickrolled

Step-by-step explanation:

\_( XD)_/

Answer:

6 times

Step-by-step explanation:

'one' 50 cents, other 10 cents

If you get 50 cents you have to roll other number 5 times to minus 50 cents (50 divided by 10 is 5)

because they got nothing after roll so if they get a cents they have to minus it rolling other number

So if you divide 30 (the number of rolling) by 5 (the number of times to minus 50 cents) so the answer will be 6

Step-by-step explanation:

Answer: [tex]\frac{x}{2}[/tex] + [tex]\frac{31y}{2}[/tex]

Step-by-step explanation:

1) Combine multiplied terms into a single fraction.

[tex]\frac{1}{2}[/tex] x + [tex]\frac{31}{2}[/tex] ⋅ y

2) Multiply the equation by 1.

1x/2+ 31/2 ⋅ y

x/2 + 31/2 ⋅ y

3) Combine multiplied terms into a single fraction.

x/2 + 31/2 y

x/2 + 31y/2

4) Solution

x/2 + 31y/2

Answer:

12

Answer:

ODD function

Step-by-step explanation:

Notice that there are two curves.  Any point on one curve reflected through the origin is found on the other curve.  In other words, the curves are symmetric with respect to the origin.  Such curves typify ODD functions.

Answer:

Step-by-step explanation:

simplifying the equation -6x + 8y = 12 dividing by 2 would give us the same equation as

-6 / 2x + 8 / 2y = 12/2

-3x + 4y = 6

Answer:

  6

Step-by-step explanation:

We estimate the number as 49/8 ≈ 6. We can check to see if this is too many by finding the chain required for 6 bracelets:

  6 × 8 1/4 = 6×8 +6×1/4 = 48 +6/4 = 49 1/2

Sue can make 6 bracelets.

_____

You can also divide the total length of chain by the amount per bracelet:

  (49 1/2)/(8 1/4) = (99/2)/(33/4)

  = (99/2)(4/33) = (99/33)(4/2)

  = (3)(2) = 6

Answer:

 6

Step-by-step explanation:

We estimate the number as 49/8 ≈ 6. We can check to see if this is too many by finding the chain required for 6 bracelets:

 6 × 8 1/4 = 6×8 +6×1/4 = 48 +6/4 = 49 1/2

Sue can make 6 bracelets.

_____

You can also divide the total length of chain by the amount per bracelet:

 (49 1/2)/(8 1/4) = (99/2)/(33/4)

 = (99/2)(4/33) = (99/33)(4/2)

 = (3)(2) = 6

Answer:

so 2 rupees tax for every 100rupees

we need to find how many 100's in 1440 and multiply with 2 so first divide 1440by 100 you will get 14.4 and multiply with 2 so the income tax is 28.8 you need to pay total 172.8.

Answer:

It would take 12 men 4.5 (four and a half) days to do the same amount of work as the 9 men in 6 days.

Step-by-step explanation:

9 is 75% of 12 (12*.75=9) if they work at the same rate it would take 75% of the time it did for the 9 men (6hrs*.75=4.5)

Answer:

Actual answer would be 77.75 but you would answer as 78 I believe.

Step-by-step explanation:

Since they're over the same denominator this means that 4n= 311.

311/4=n

n=77.75

Or for you it would be 78 rounded up.

Or for a fraction it would be 77 1/4.

Answer:

x = 15

Step-by-step explanation:

Given

5x + 55 = 2x + 100 ( subtract 2x from, both sides )

3x + 55 = 100 ( subtract 55 from both sides )

3x = 45 ( divide both sides by 3 )

x = 15

Poorly formated. Please fix the question so it is more understandable!

Answer:

1)0.0275

2)3.9×10^10

3)2×10^-6

4)did u mean 10^4?

if so then it would be 73,680

explanation

1)2.75×10^-2

2.75×.01=0.0275

2)39,000,000,000.00

in scientific notations the first number has to be lower than 10 and higher than 1>

3.9 works so i would take the dot/period and bring it between 3 and 9, the dot would travel 10 places therefore you raise the 10 to the 10th power

3.9×10^10

4) and since 10 is raised to the 4th power you would just move the dot 4 places right and you get

7.368>73,680

Answer:

Step-by-step explanation:

so this equation is in y = mx + b form or slope intercept form

you can see that the slope is 3x since mx is slope

remember! m is always slope!
