Please help me 2x-7/8+x=2x+7/2+5

Elina [12.6K]

Answer:

$x = \frac{75}{8}$

Step-by-step explanation:

So we have this:

$2x - \frac{7}{8} + x = 2x + \frac{7}{2} + 5$

First, let's combine like terms:

$3x - \frac{7}{8} = 2x + \frac{7}{2} + \frac{10}{2} \\3x - \frac{7}{8} = 2x + \frac{17}{2}$

Next, let's move variables and numbers each onto their own sides to get our answer:

$3x - \frac{7}{8} + \frac{7}{8} = 2x + \frac{17}{2} + \frac{7}{8}\\ 3x = 2x + \frac{75}{8} \\3x - 2x = 2x + \frac{75}{8} - 2x\\\ x = \frac{75}{8}$

What would be the volume of the box if it’s factor is scaled down by 1/10? The volume is 130 inches

goldfiish [28.3K]

Answer:

27 units (whatever units the figure was measured in)

Step-by-step explanation:

Volume is length times width times height. So, you would need to do 9 times 3 (27) times 10 (270). Then, you would divide by 10, because it is scaled down by 1/10, leaving you with 27.

Use the quadratic formula x^2-5x+3=0

kifflom [539]

Answer:

$x^2 -5x +3 = 0\\\\ x= \frac{-b \pm \sqrt{b^2-4*a*c} }{2a} \\\\b = -5, a = 1 , c = 3\\\\x= \frac{-b + \sqrt{b^2-4*a*c} }{2a} , x= \frac{-b -\sqrt{b^2-4*a*c} }{2a}\\\\x= \frac{5 + \sqrt{25-12} }{2}, x= \frac{5-\sqrt{25-12} }{2}\\\\x= \frac{5+\sqrt{13} }{2}, x= \frac{5- \sqrt{13} }{2}$
