Answer:

x = - \frac{29}{7}

Step-by-step explanation:

\frac{x+1}{4} + \frac{x+2}{2} = \frac{x-3}{2} - \frac{x-1}{3}

Multiply through by 12 ( the LCM of 4, 2, 3 ) to clear the fractions

3(x + 1) + 6(x + 2) = 6(x - 3) - 4(x - 1) ← distribute parenthesis on both sides

3x + 3 + 6x + 12 = 6x - 18 - 4x + 4 , that is

9x + 15 = 2x - 14 ( subtract 2x from both sides )

7x + 15 = - 14 ( subtract 15 from both sides )

7x = - 29 ( divide both sides by 7 )

x = - \frac{29}{7}

Answer:

Well do you know the butterfly method

you multiply 2 by x+1 and 4 by x + 2

Step-by-step explanation:

2(x+1) + 4(x+2) = 3(x-3) -2(x - 1)

2x + 2 + 4x + 8 = 3x - 9 - 2x + 2

2x + 4x +8 = 3x - 2x -9 +2

6x + 8 = x -7

6x - x = -7 -8

5x = -15

x = -15/5

x = -3

Determine the height of a square pyramid with a volume of 225 cubic inches and a base edge of 5 inches.
ss7ja [257]

Answer:

h = 27 inches

Step-by-step explanation:

Given that,

The volume of a square pyramid, V = 225 inches³

The base edge of a square pyramid, b = 5 inches

We need to find the height of a square pyramid. The formula for the volume of a square pyramid is given by :

V=\dfrac{1}{3}B\times h

B is area of base, B = b²

So,

h=\dfrac{3V}{b^2}\\\\h=\dfrac{3\times 225}{5^2}\\\\h=27\ \text{inches}

So, the height of the square pyramid is 27 inches.

Suzanne and Jane made some cookies. They gave 1/3 to their friends, ate 1/4 of the remaining cookies, and froze the rest to eat
Licemer1 [7]
9 cookies is 1/4 of the remaining cookies, therefore you can multiply by 4 to have 36 cookies, they gave away 1/3 before this, so you then multiply by 3/2 for 54 cookies

3x^3 - 12x has a greatest common factor of 3x.

3x(x^2 - 4) is one other way to write it. It was created by factoring out the GCF of 3x.

3x(x+2)(x-2) is another form which is created by factoring the (x^2 - 4) from the last form.
