Answer:

Which are equivalent expressions?

Check all that are true.

y + x = 2x

x + x + x + x = 4x (true)

x + x = 2x (true)

x + y + y + x = 2x + 2y (true)

x + y + x + x = 2x + y

What is the square root of 25p^3 expressed in simplified form?
notka56 [123]
The first step to solving this is to factor out the perfect square of 5²
\sqrt{ 5^{2}  p^{3} }
next,, factor out the perfect square of p³
\sqrt{ 5^{2}  p^{2} x p}
the root of a product is equal to the product of the roots of each factor 
√5² √p² √p
now reduce the first index of the radical and the exponent with 2
5√p² √p
then reduce the second index of the radical and exponent with
5p√p
this means that the correct answer to your question is 5p√p

I need the working to the 2nd one
Aleksandr [31]

Answer:

y= -33/32

Step-by-step explanation:

or, 2y/3-3/3=2y+5/8

or, 2y/3-2y=5/8+3/4

or, (2y-3*2y)/3=(5+3*2)/8

or, (2y-6y)/3 = (5+6)/8

or, (-4y)/3 = 11/8

or, 8*(-4y) = 11*3

or, -32y =33

or, -y =33/32

or, y= -33/32

I'm so confused. Please help I tried the first time got 50 some thing then 33 then 20.25. How do I do this?
vazorg [7]

Answer:

Basically, you have to think: more bricks : more time

more workers : less time

2,400 bricks 6 workers takes 18 hours

You now have to solve for 4,500 blocks and 10 workers

4,500 / 2,400 = 1.875 (times greater)

10 / 6 = 1.666666666 (times less)

So, we get 18 hours, multiply it by 1.875 and divide it by 1.666666666

which equals 20.25 hours

So, it seems you were correct on your third try.
