Answer:

if your looking for x then

Step-by-step explanation:

first add in the y by doing 10x+5(2x-3)=15 then 10x+10x-15=15 then 20x-15=15 then 20x=30 then divided by 20 for both sides which gets you x=30/20 or 1 1/3

Solve for T. B=RT-4/6

lions [1.4K]

I’m not sure which of these you meant to type so I answered both ways
B=(RT-4)/6 multiply by 6
6B= RT-4. Add 4
6B+4= RT. Divide by R
(6B+4)/R = T

Or B=RT -4/6. Multiply by 6
6B=6RT -4. Add 4
6B+4= 6RT. Divide by 6R
(6B-4)/6R = T. Reduce
(3B-2)/3R = T

How do you do this and what’s the answer to this I been stuck on this question for litterly 20 mins

$\bf T=2\pi \sqrt{\cfrac{L}{g}}\implies \stackrel{\textit{squaring both sides}}{(T)^2=\left( 2\pi \sqrt{\cfrac{L}{g}}\ \right)^2}\implies T^2=2^2\pi^2\sqrt{\left( \cfrac{L}{g} \right)^2} \\\\\\ T^2=4\pi^2\cfrac{L}{g}\implies T^2=\cfrac{4\pi^2L}{g}\implies gT^2=4\pi^2L\implies g=\cfrac{4\pi^2L}{T^2}$
