Convert 244 cm to feet  = 8.00 ft

two walls at  16.25   x 8 ft     =   2  X   16.25   x  8  = 264 sq ft

two walls at   12.3    x 8 ft     =   2  x     12.3    x  8  = 196.8 sq ft       total = 460.8 sq ft

Amount of paint needed     460.8 ft²  /  350 ft²  / gal  = ........ gallons

10 km   +   5km/hr   *  x       = y

So its16?

You should post this separately as a standalone question

x    first integer

x+1 = second integer   summed = 129

x     + x+1 = 129

2x = 128

x = 64       x+1 = 65

'a' slope =   (y1-y2)/ (x1-x2) =   (8-17)/(4-8) = -9/-4 = 9/4

parallel slope, m is the same = 9/4

New line     thru -12,20

(y-20) = 9/4 (x+12)

PLease help!

-28/3 is not the right answer though

I will assume consecutive to mean that the integers have a difference between them of 1.

We can now define 2 integers, a and b, and say that a > b.

From this we know that, given the difference is equal to one: a + 1 = b.

We also know that a + b = 129.

Substituting the alternative form of b in, we have: a + (a + 1) = 129.

After combining terms (grouping), we have: 2a + 1 = 129.

After isolating variables (getting a alone on one side), we get 2a = 128, which, when dividing each side, resolves into a = 64.

Plugging a back into the above equation, we find b = (64) + 1, or b = 65.

The consecutive integers are therefore 64 and 65.

I'll assume that given how we are given an incomplete value for x we can assume that the point is 6 distance from the x axis, leaving us with a y-value of + or - 6.

Given how the most y-negative value possible is -2 (assuming straight negative y travel), we can safely eliminate -6 as a possibiility for y, and find y to be +6.

Solving for a point with y=6 a distance of 5 units away from (8,3), by using a memorized pythagorean triple of 3-4-5, you can know that the x value is 8 plus or minus 4 units.

Given that x is less than 8, the lower answer of 4 is the only one that is possible, hence x = 4.

We now know that (x,y) is located at (3,4).

Solving for distance from the origin, we could use the pythagorean theorem, but this is another use of the same pythagorean triple. We know that it is 5 units from the origin.

Putting this back with n, we now have sqrt(n) = 5

Squaring each side to solve for n alone, we find n = 25.

If use of the pythagorean theorem is required I will be happy to supply it.

This post does not appear to contain a math-related question, could you mark it as off topic?

From x + 3y = -5, y = -x/3 - 5, so the slope of the line is -1/3. The slope of the new line is also -1/3, so y = -x/3 + B.  Pugging in x = 2 and y = -7, we get -7 = -2/3 + B, so B = -19/3.

Then the line is y = -x/3 - 19/3.  Then 3y = -x - 19, so 3y + x = -19.  We want the right-hand side to be 3, so we mutiply both sides by -3/19: -9/19*y - 3/19*x = 3.  Therefore, B - A = -19/3 - 3 = -28/3.

What is the volume?

Hello Guest!

\(V=(3\times 15+3\times 10)cm^2\times 3cm\)

\(V=225cm^3\)

  !

The sum of two consecutive integers is 129.  Find both integers. 

please halpppppp

Please help with a and b.
