The unknown number is n. So n is the unknown variable in the equation.
In order to write an equation in which n is included we must know some dependence of n with other values.
We know that <span>the difference of three times a number and 44 is −19. So, we can write:
3*n-44=-19
3*n=-19+44
3*n=25
n=25/3

What’s the original volume
anzhelika [568]

Answer:

V = 1959.75ft²

Step-by-step explanation:

The volume is equal to the height of the barrel times (π × r²)

V = h(πr²)

V = 10.8(π × 7.6²)

= 10.8(π × 57.76)

= 10.8(181.46)

V = 1959.75ft²

Write 15 1/4% as a fraction (not as a percentage
Monica [59]

Answer:

151/1000

Step-by-step explanation:

To convert 15.1 percent to a fraction follow these steps:

Step 1: Write down the percent divided by 100 like this:

15.1% = 15.1/100

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As we have 1 digit after the decimal point, we multiply both numerator and denominator by 10, or, simply shift 1 decimal place to the right. So,  

15.1/100 = (15.1 x 10)/(100 x 10) = 151/1000.

(This fraction is alread reduced, We can't reduce it any further).

Please show work!!!!!!!!!!!!
Svetlanka [38]

Answer:

x = 7

Step-by-step explanation:

Notice that in the triangle, the angle is either known or in terms of x. This means we can make an equation: 82 + (9x - 6) + (6x - 1) = 180. Now, add up tthe terms to get 15x + 75 = 180, or 15x = 105 or x = 7.
