Which of these equations, when solved, gives a different value of x than the other three? 9.1 = -0.2x + 10 10 = 9.1 + 0.2x 10 –
2 answers:
Given:
Different equations are given.
Rhyan paid using a gift card that had $22.20 on it. After the sale, Rhyan's gift card had $1.90 remaining.
To find:
The equation which gives a different value of x than the other three.
To find the equations that could you use to find the price of one tire patch.
Solution:
In option A,
Divide both sides by 0.2.
Similarly,
In option B,
In option C,
In option D,
Since option D has difference solution, therefore the correct option is D.
Let price of one tire patch be x.
So, price of 4 tire patches = 4x
Remaining amount in Rhyan's gift card = $1.90
Total amount = $22.20
Price of 4 tire patches + Remaining amount in gift card = Total amount
It can be written as
Therefore, the correct options are C and E.

The voltage is a representation of the electric potential energy per unit charge.
The voltage across the circuit is 48 V. Option D shows the voltage across the circuit.
<h3>What is the voltage?</h3>
Voltage is defined as the difference in electric potential between two points.
Given that a series circuit contains three 2 Ω resistors and a 6 Ω resistor. The current in each resistor is 4.0 A.
The total resistance across the series circuit is given below.
Where R is total resistance, R1, R2, R3 and R4 are resistors that are connected in series.
The resistors are connected in series hence the current flows across the two points of the circuit are the same which is 4.0 A.
The voltage across the circuit is,
Hence we can conclude that the voltage across the circuit is 48 V. Option D shows the voltage across the circuit.
