Answer:
Step-by-step explanation:
We know that it costs 3.50 dollars for a gallon of gas, so we can write the total cost as an expression.
Expression: c= 3.50g
To find the total cost for 5 gallons, plug 5 into the variable, g.
c= 3.50g
c= 3.50(5)
c= 17.5 dollars
If a line is parallel to another, the slopes of both lines are the same. So for this problem, you can infer that the slope of the line you're trying to find is 3.
To find the actual equation of the line, you can use the given coordinates and plug them into the point slope form:
y - y1 = m(x - x1)
plug the given y coordinate into y1 and the given x coordinate into x1. m is the slope, so plug in 3 for m.
y - 1 = 3(x +2) Use distributive property for right side of equation
y - 1 = 3x + 6 add 1 to both sides to cancel -1 on left side of equation and isolate y
Equation of line: y = 3x + 7
If 80 miles is 50% of his trip, then you know that 80 miles is only HALF of his entire trip. To get the distance Raul traveled in total, simply double the 80 miles. This would be 160 miles.
Raul traveled a total of 160 miles in his trip.
Answer:
Step-by-step explanation:
2x - 3x(3+2) = 10
Distribute the -3x to the numbers inside the parenthesis:
2x - 9x -6 = 10
Simplify:
-7x = 16
Isolated the x:
x = 16/-7
