Answer:
201.5x-y=-6
Step-by-step explanation:
−6x−2y=−1618x+6y=48
Collect like terms
-6x+1618x-2y-6y=-48
1612x-8y=-48
Divide through by 8
1612x/8-8y/8=-48/8
201.5x-y=-6
6x + 0.8 = 1.4....subtraction property .... subtract 0.8 from both sides
6x = 1.4 - 0.8 ...simplify
6x = 0.6 ... division property ... divide both sides by 6
x = 0.6/6 ...simplify
x = 0.1
Answer:
0
Step-by-step explanation:
1) Multiply the first equation by -3: -6x - 3y = 12
2) Substitute 2x + 12 for -3y in the above equation, obtaining:
-6x + 2x + 12 = 12
Then -4x = 0, and x = 0. Letting x = 0 in the first equation, we get:
0 + y = -4, so y = -4.
The x-value at the intersection of the lines is zero (0).
That intersection is at (0, -4).
Answer:
The unlimited mileage plan would save money for Lia from 410 miles onwards.
Step-by-step explanation:
Since Lia can rent a van for either $ 90 per day with unlimited mileage or $ 50 per day with 250 free miles and an extra 25 ¢ for each mile over 250, to determine for what number of miles traveled in one day would the unlimited mileage plan save Lia money, the following calculation must be performed:
90.25 - 50 = 40.25
40.25 / 0.25 = 161
161 + 250 = 411
Therefore, the unlimited mileage plan would save money for Lia from 410 miles onwards.
