Answer:
x ≤ 17
Step-by-step explanation:
Pick up fee = 2.80
Cost per mile = 1.25
Total cost = $24.05
Number of miles ride, x
Pickup fee + mile per ride * number of ride ≤ total cost
2.80 + 1.25x ≤ 24.05
1.25x ≤ 24.05 - 2.80
1.25x ≤ 21.25
x ≤ 17
Number one of miles ride x ≤ 17
The 4th option would be correct.
{X | - Root 5 < x < Root 5 }
Answer: 24 because you add 5 for every number ex: 9+5=14
Answer:
c.1
Step-by-step explanation:
Answer: 15 dimes
Step-by-step explanation:
Nickels are 5 cents and dimes are 10 cents and since they are a total of 1.95 coins in total we can set up the two equations and solve for how much there are for each of the money.
x + y = 24
0.05x + 0.10y = 1.95 so solve for y and x is the number of nickels while y is the number of dimes.
x+y=24
-y -y
x = -1y +24
0.05(-1y +24) + 0.10y = 1.95
-0.05y + 1.2 + 0.10y = 1.95
0.05y + 1.2 = 1.95
-1.2 -1.2
0.05y = 0.75
y = 15
