Most mistakes people make when doing this kind of math is that they forget the X and move along.
So, let's solve for X --
38 + x = 32
° Step 1 - Simplify both sides of the equation.
x + 38 = 32
° Step 2 - Subtract 38 from both sides.
x + 38 - 38 = 32 - 38
We can now see that x = -6. Well, at least you were close! All you forgot was the negative sign!
x = -6

Answer:
zero
Step-by-step explanation:
The lines are parallel ( they have the same slope)
the slope is 1/2 ( up 1 over 2)
The y intercept is different.
The lines will never intersect.
Therefore there are zero solutions
Answer: Zero
Step-by-step explanation: Since the lines are parallel, the two lines will never be able to meet.
which is the dependent and independent variable
Lou spends the total amount would be $26.98 on gas which is determined by subtracting 13 gallons and 5.9 gallons and multiplying the result by $3.80.
Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
The following information is provided in the problem :
Lou topped up the tank with $3.80 per gallon of petrol.
Lou's car's 13-gallon tank held 5.9 gallons.
If he filled the tank, you can determine the total amount of money Lou spent by subtracting 13 gallons and 5.9 gallons and multiplying the result by $3.80.
So the total amount would be:
⇒ (13 - 5.9)(3.80)
⇒ (7.1)(3.80)
⇒ 26.98.
Therefore, the total amount would be $26.98
