135 is 30% of what number

Mathematics
1 answer:
V125BC [204]3 years ago
4 0
So,

135 is 30% of x

135 = 30% of x

135 = 30% * x

135 = 0.3x

135= \frac{3}{10}x

Multiply both sides by the reciprocal.

135* \frac{10}{3} =x

\frac{135*10}{3} =x

\frac{45*10}{1}\ or\ 450 =x

135 is 30% of 450.

Solve 10e^2x - 5 =23^x for x.
yawa3891 [41]

10e^{2x}-5=23e^x\qquad\text{subtract}\ 23e^x\ \text{from both sides}\\\\10e^{2x}-23e^x-5=0\\\\10(e^x)^2-23(e^x)-5=0\\\\\text{substitution:}\ e^x=t > 0\\\\10t^2-23t-5=0\\\\10t^2-25t+2t-5=0\\\\5t(2t-5)+1(2t-5)=0\\\\(2t-5)(5t+1)=0\iff2t-5=0\ \vee\ 5t+1=0\\\\2t=5\ \vee\ 5t=-1\\\\t=\dfrac{5}{2} > 0\ \vee\ t=-\dfrac{1}{5} < 0\\\\\text{therefore}\ e^x=\dfrac{5}{2}\to\ln e^x=\ln\left(\dfrac{5}{2}\right)\\\\\boxed{x=\ln\left(\dfrac{5}{2}\right)}
