What is the true solution to the equation below?
Naddik [55]
Yeeee

assuming your equaiton is
2ln(e^{ln(2x)})-ln(e^{ln(10x)})=ln(30)


remember some nice log rules
log_a(b)=c translates to a^c=b
and
a^{log_a(b)}=b
and
xlog_c(b)=log_c(b^x)
and
ln(x)=log_e(x)
and
log(a)-log(b)=log(\frac{a}{b})
and
if log(a)=log(b) then a=b

so

we can simplify a bit of stuff here

the e^{ln(2x)} \space\ and \space\ the \space\ e^{ln(10x)} can be simplified to 2x \space\ and \space\ 10x

so we gots now

2ln(2x)-ln(10x)=ln(30)
ln((2x)^2)-ln(10x)=ln(30)
ln(4x^2)-ln(10x)=ln(30)
ln(\frac{4x^2}{10x})=ln(30)
same base so
\frac{4x^2}{10x}=30
\frac{2x}{5}=30
times both sides by 5
2x=150
divide both sides by 2
x=75
answer is x=75

Can someone please help me with this plss and thanks
dolphi86 [110]

4x + 32 - 4 = 34 - 2x

4x + 28 = 34 - 2x

4x = 34 - 2x - 28

4x = -2x + 6

4x + 2x = 6

6x = 6

x = 1

If you could travel 450 miles in 5.5 hours, then how far could you travel in 7 hours?​
GrogVix [38]

Answer:

I will use x as the distance traveled in 7 hours

450/5.5 = x/7.7 - set up proportion

5.5x = 3465 - cross products

5.5x/5.5 = 3465/5.5 - divide each side by 5.5

x = 630 - answer

hope this helps.
