Hi friend,
((5+a)/a)/((a^2 -25) /5a)
=(a+5)/((a^2 - 25)/5)
=(a+5)(5)/(a+5)(a-5)
=5/(a-5)
Therefore your answer is B)
Hope this helps you!

Nitella [24]

<u>Answer:</u>

Heather = 18 messages

Brian = 25 messages

Austin = 54 messages

<u>Step-by-step explanation:</u>

We know that Heather, Brian, and Austin sent a total of 97 messages.

Assuming the number of messages sent by Brian as x, we can say that Heather sent x-7 messages (7 fewer messages than Brian) and Austin sent 3(x-7) messages (3 times as many as Heather).

$(x-7)+x+3(x-7)=97\\\\x-7+x+3x-21=97\\\\5x=97+21+7\\\\5x=125\\\\x=25$

So Brian sent (x) messages = 25 messages,

Heather sent (x-7) messages = 25 - 7 = 18 messages; and

Austin sent 3(x-7) messages = 3(25-7) = 54 messages

Answer:

x = 3

Step-by-step explanation:

$In\: \triangle PQT,\: \overline{PQ}|| \overline {RS}...(Given)\\\\\implies\frac{PS}{ST}=\frac{QR}{RT}\\(By\: Proportionality\: Theorem) \\ \\\implies\frac{2x+4}{5}=\frac{3x+5}{7}\\\\ \implies \: 7(2x + 4) = 5(3x + 5) \\ \\ \implies \:14x + 28 = 15x + 25 \\ \\ 14x - 15x = 25 - 28 \\ \\ - x = - 3 \\ \\ x = 3$

Answer:

For a confined, constant volume of gas, the ratio

is therefore constant (i.e.,

). If the gas is initially in “Condition 1” (with P = P1 and T = T1), and then changes to “Condition 2” (with P = P2 and T = T2), we have that
