Answer:
1.1 gigabytes
Step-by-step explanation:
Let us represent:
The number of gigabytes = g
Under his cell phone plan, Owen pays a flat cost of $67.50 per month and $4 per gigabyte. He wants to keep his bill at $71.90 per month.
The Equation is given as:
$71.90 = $67.50 + $4 × g
71.90 = 67.50 + 4g
71.90 - 67.50 = 4g
4.4 = 4g
x = 4.4/4
x = 1.1 gigabytes
Therefore, the number of gigabytes of data Owen can use while staying within his budget is 1.1 gigabytes
Let x = number of 5 cent coins.
Then there are (x+2) 10 cent coins.
Let y = 20 cent coins.
Total coins: x+(x+2)+y = 30
2x+y=28
y = 28-2x (1)
Total value: 0.05x + 0.1(x+2) + 0.2y = 3.80
0.15x + 0.2y + 0.2 = 3.80
0.15x + 0.2y = 3.60 (2)
Substitute (1) into (2).
0.15x + 0.2(28-2x) = 3.60
-0.25x + 5.60 = 3.60
2.00 = 0.25x
8 = x
From (1), obtain y = 28 - 2(8) = 12
Answer: (x+2) = 8+2 = 10

<h3>How to understand power properties</h3>
Herein we must explain some properties of power expressions with integer exponents. A power of the form aᵇ is a product of the form a × a × a × a × ... × a, where a is repeated b times. a and b are the base and the exponent of the power.
First, we proceed to demonstrate that a⁰ = a:
a⁰ Given
a¹ ⁻ ¹ Existence of the additive inverse / Modulative property
a¹ · a⁻¹ Multiplication of powers of equal base
a¹ · (a¹)⁻¹ Power of a power / (- a) · b = - a · b
1 Existence of multiplicative inverse / Modulative property / Result
By definition of power, we find that a¹ as a is only only time.
