Answer:

x = 5/4

Step-by-step explanation:

By combining like terms, you get 8x = 10.

Divide the 8 on both sides of the equation.

x = 10/8

This, however, can be simplified by dividing by 2. This ultimately gives us 5/4.

Answer:

x=5/4

Step-by-step explanation:

Hi there! I'd be happy to help you solve this equation!

To combine the equation 3x+5x=10's "like" terms, you simply add the 3 and 5, resulting in 8, being sure not to leave out the x.

Now we're left with 8x = 10.

Solve for x: Divide both sides of the equation by 8. You can use a calculator!8x/8 = 10/8

Hence, our answer is now x = 5/4.

I hope this helped you! Comment below if you think I've made a mistake or would like further explanation! <3

Solving Exponential and Logarithmic Equations In Exercise, solve for x. 4e2x - 3 - 5 = 0

Deffense [45]

Answer:

Value of x will be 0.1515

Step-by-step explanation:

We have given the equation $4e^{2x}-3-5=0$

We have top fond the value of x using exponent and logarithmic property

So $4e^{2x}-3-5=0$

$4e^{2x}-8=0$

$4e^{2x}=8$

$e^{2x}=2$

Taking log both side

$lne^{2x}=ln2$

$2x=0.3010$

x = 0.1515

Answer is option d)346.4 ft

Step-by-step explanation:

$from \: the \: figure \\ AB = 300 \: ft \: \: \: angle \: C = 60 \:( theta)\: degress \\ in \: triangle \: ABC \: using \: tan \: theta\\ \tan(60) = \frac{opposite \: side}{adjacent \: side} \\ \tan(60) = \frac{300}{BC} \\ \sqrt{3} = \frac{300}{BC} \\ BC = \frac{300}{ \sqrt{3} } \\ BC = 100 \sqrt{3} ft \\ then \: in \: triangle \: ABD \: using \: tan \: theta \\ angle \: D = 30 \: degrees \: (theta) \\ \tan(30 ) =\frac{opposite \: side}{adjacent \: side} \\ \tan(30) = \frac{300}{BD} \\ \frac{1}{ \sqrt{ 3} } = \frac{300}{BD} \\ BD = 300 \sqrt{3} \\ CD = BD - BC \\ = 300 \sqrt{3 } - 100 \sqrt{3} \\ = (300 - 100) \sqrt{3} \\ = 200 \sqrt{3 } \\ = 200 \times 1.732 \\ = 346.4 \: ft$
