Answer:

1) Inequality: 110x>150+85x

2) Solution: x>6, then Nadia would need to sell more than 6 ads per week in order for Choice A to be the better choice,

<u>Solution:</u>

Be x the number of ads Nadia sells

A) Choice A: $110 for each ad she sells. She would earn:

Ea=110x

B) Choice B: A weekly salary of $150, plus $85 for each ad she sells. She would earn:

Eb=150+85x

1) Write an inequality to determine the number of ads Nadia would need to seel per week in order for Choice A to be the better choice:

Ea>Eb

110x>150+85x

2) Solution

Solving for x: Subtracting 85x both sides of the equation:

110x-85x>150+85x-85x

Subtracting:

25x>150

Dividing both sides of the equation by 25:

25x/25>150/25

Dividing:

x>6

Find the value of x that makes this statement true

Brrunno [24]

$\frac{(-2)^{5x-3}}{(-2)^{2x}} =(-2)^{21}$

$(-2)^{5x-3-2x}=(-2)^{21}$ (The numerator and the denominator has same bases, therefore the powers will get subtracted. It is an exponential property)

$(-2)^{3x-3}=(-2)^{21}$

$3x-3=21$ (As the left hand side is equal to right hand side and the bases are on both the sides are equal too, we will equate their exponential power. Another property)

$x-1=7$

$x=8$ (After simplifying more, you'll get this)
