Subtract 2 from both sides (subtract 5-2=3) and the 2 cancels out . now you have -3x=3, all you do now is divide 3 by -3 and you should get 1. ANSWER=1

Explain how to solve 4^(x+3)=7 using the change of base formula log_by=log y/ log b. Round to the nearest thousandth

HACTEHA [7]

Answer:

x = -1.59

Step-by-step explanation:

We are here given a equation and we need to solve out for x. The given equation is ,

$\sf\longrightarrow 4^{( x +3)}= 7$

Take log to the base " e " on both sides , so that we can remove the variable from the exponent .

$\sf\longrightarrow log_e 4^{x+3}= log_e 7$

Simplify using the property of log , $\sf log a^m = m log a$ , we have ,

$\sf\longrightarrow (x + 3) ln 4 = ln 7$

Distribute by opening the brackets ,

$\sf\longrightarrow x ln 4 + 3 ln 4 = ln 7$

This can be written as ,

$\sf\longrightarrow x ln 4 = ln 7 - 3ln4$

Divide both sides by ln 4 ,

$\sf\longrightarrow x = \dfrac{ ln7}{ln 4 } - \dfrac{ 3ln4}{ln4}$

Simplify ,

$\sf\longrightarrow x = \dfrac{ ln4 }{ln7 } -3$

On simplifying , we will get ,

$\sf\longrightarrow \boxed{\blue{\sf x = -1.59 }}$

A car travels 120 miles in 3 hours (with a constant ) how far will it take to travel 200 miles?

Zina [86]

120 miles = 3 hours
1mile = 3/120 = 1/40
200 miles = 1/40 times 200
= 5 hours

Simplify the ratio 14/20

poizon [28]

To simplify a ratio, whatever you do to the bottom, you must do to the top. Find the GCF of both numbers, then divide until you can no longer simplify. I showed my work on a sheet of paper for a visual look.
