Geoff and Max are college roommates. Geoff can clean their apartment in 2.5 hours and Max can clean their apartment in 3.25 hour

Anestetic [448]

Answer: 1.41 hours

Step-by-step explanation:

Geoff: 2.5 hours = 1 job

Max: 3.25 hours = 1 job

Together: $\frac{x}{2.5} + \frac{x}{3.25} = 1 job$

⇒ $(3.25)(2.5)\frac{x}{2.5} + (3.25)(2.5)\frac{x}{3.25} = (3.25)(2.5)1$

⇒ 3.25x + 2.5x = 8.125

⇒ 5.75x = 8.125

÷5.75 ÷5.75

x = 1.413

Pls dont guess on it

yuradex [85]

Answer:

2(8a + 8)

Step-by-step explanation:

The easiest way to do this is to substitute a for a number. For example, let's just make things easy and make a = 1.

So, if a = 1, the expression 16a + 8 would be 16(1) + 8 = 24.

Let's find all the expressions that would also equal 24 if a = 24.

Plug in 1 for a in each of the equations. You will find that 2(8a + 8) will not equal 24 if a equals 1.

2(8a + 8)

2(8(1) + 8

2(8 + 8)

2(16)

Can someone help me please ???????

Answer:

d=1

Step-by-step explanation:

Factor d^2 - 2d - 8 into (d-4)(d+2)

Move -2/d+2 onto the other side, changing it into 2/d+2.

$\frac{-3d}{(d-4)(d+2)} +\frac{3}{d-4}+\frac{2}{d+2} = 0$

Let the empty side equal zero.

Add 3/d-4 and 2/d+2

$\frac{5d-2}{(d+2)(d-4)}$

Then add that to -3d.

$\frac{2d-2}{(d+2)(d+4)}$

Multiply 0 by d+2 and d-4 to get 2d-2 by itself.

2d=2

d=1

I can't edit the equation, but it's d-4 althroughout the question. Sorry for being so slow.
