Answer: I think its B and C
<span><span>(<span><span>5x</span>+7</span>)</span><span>(<span>1/5</span>)</span></span>=<span><span>(<span>8−<span>6x</span></span>)</span><span>(<span>1/5</span><span>)
</span></span></span>Simplify both sides. In order to do this you need to distribute 1/5 in each expression.
<span><span><span>(<span>5x</span>)</span><span>(<span>1/5</span>)</span></span>+<span><span>(7)</span><span>(<span>1/5</span>)</span></span></span>=<span><span><span>(8)</span><span>(<span>1/5</span>)</span></span>+<span><span>(<span>−<span>6x</span></span>)</span><span>(<span>1/5</span><span>)
</span></span></span></span><span>x+<span>7/5</span></span>=<span><span>8/5</span>+<span><span><span>−6/</span>5</span><span>x
</span></span></span><span>x+<span>7/5</span></span>=<span><span><span><span>−6/</span>5</span>x</span>+<span>8/<span>5
Now you need to add (-6/5)x to both sides. This leaves you with
</span></span></span><span><span><span>(5/11)</span>x</span>+<span>7/5</span></span>=<span>8/<span>5
Now subtract 7/5 from both sides.
</span></span><span><span>(5/11)</span>x</span>=<span>1/<span>5
Divide both sides by 5/11
x=1/11</span></span>
Answer:
Step-by-step explanation:
The given equation is :
Where
P is pressure
V is volume
n is no of moles
r is Gas constant
T is temperature
We need to solve the above equation for r.
Dividing both sides of the above equation by (nT). So,
So, the value of r is equal to 
.
Answer:
(-1)* (3)^(n-1)
Step-by-step explanation:
common ratio is 3 and the first term is -1
the explicit formula is a * r^ ( n-1)
i.e., (-1) * 3^(n-1)
<span>divide the smaller number by the larger number
</span>
36/40
<span>is 9/10 </span>
which is 90%
