Write equations for both companies:
Company A = 80 + 0.30x
Company B = 20 + 0.50x
X = number of miles.
Set the equations to equal and solve for x:
80 + 0.30x = 20 + 0.50x
Subtract 0.30x from both sides:
80 = 20 + 0.20x
Subtract 20 from both sides:
60 = 0.20x
Divide both sides by 0.20:
x = 60 / 0.20
x = 300
The answer is 300 miles.
This product involves zero. So, you don't have to bother and compute all the factor, because if you multiply anything by zero you get zero.
Answer:
12n+5
Step-by-step explanation:
The difference is 12 so that means n is 12 and the +5 is what the number in the sequence is before 17
Answer:
x = y
Step-by-step explanation:
7x = 5y + 2x
Subtract 2x from both sides
5x = 5y
x = y
