Which expression is equivalent to one over 3p + 15?
Doss [256]

we know that

the expression " one over (3p+15)"  is equivalent to

\frac{1}{(3p+15)} --------> expression A

and

 3p+15=3(p+5) --------> expression B

substitute the expression B in the expression A

\frac{1}{(3p+15)}=\frac{1}{3(p+5)} -----> one over three(p + 5)

therefore

<u>the answer is the option </u>

one over three(p + 5)

The sum of two numbers is 74. The larger number is 3 more than the smaller number. Find the numbers.
nlexa [21]

Answer: It's 35.5 and 38.5


Step-by-step explanation:

First, subtract 74 by 3  giving you 71.

Next, divide 71 by 2; it gives you 35.5 (that's your first number).

Then, add the 3 that you took away to 35.5 and get 38.5 (that's your second number).

What is the square root of 78
Pavel [41]
The square root of 78 is an irrational number, so the exact number
can't be written down, no matter how long you make the decimal.

If I say it's  8.8318, then my answer is too big, but only by about 0.0004 percent.
