Or what value of x does 4x=(1/8)^x+5?<br> –15<br> –3<br> 3<br> 15

liq [111]

Answer:

<h2>x = -3</h2>

Step-by-step explanation:

$4^x=\left(\dfrac{1}{8}\right)^{x+5}\qquad\text{use}\ a^{-1}=\dfrac{1}{a}\\\\4^x=(8^{-1})^{x+5}\\\\(2^2)^x=\bigg((2^3)^{-1}\bigg)^{x+5}\qquad\text{use}\ (a^n)^m=a^{nm}\\\\2^{2x}=2^{-3(x+5)}\iff2x=-3(x+5)\qquad\text{use the distributive property}\\\\2x=-3x-15\qquad\text{add}\ 3x\ \text{to both sides}\\\\5x=-15\qquad\text{divide both sides by 5}\\\\x=-3$

What is the answer to 2a-3=7

ladessa [460]

2a−3=7

Add 3 to both sides.

2a−3+3=7+3

2a=10

Divide both sides by 2.

2a / 2 = 10 / 2

a=5

The City Sights tour company had the same ratio of tourists to guides on both days this weekend. On Saturday, there were 120 tou

Anastasy [175]

Answer:

There were 6 guides on Sunday.

Step-by-step explanation:

Same ratio

On Saturday, 120 tourists and 18 guides.

On Sunday, 40 tourists and x guides.

Due to the same ratio:

$\frac{120}{40} = \frac{18}{x}$

$3 = \frac{18}{x}$

$3x = 18$

$x = \frac{18}{3}$

$x = 6$

There were 6 guides on Sunday.
