a) The cost for 10 mile taxi ride is $18
b) The cost for m mile taxi ride is 1.5 m + 3
Step-by-step explanation:
Step 1 :
The fixed charges for the pick up = $3
Charges per mile = $1.50
Let s denote the total miles driven and t be the total cost for the trip
This can be represented by the equation
t = 3 + 1.5s
Step 2:
Distance traveled by Jonathan in his trip = 10 miles
So cost for riding 10 miles is
t = 3 + 1.5(10) = 3 + 15 = $18
The cost for 10 mile taxi ride is $18
Step 3 :
If the distance traveled is m miles, then substituting s = m in the above equation we get the cost as 1.5 m + 3
Step 4 :
Answer :
a) The cost for 10 mile taxi ride is $18
b) The cost for m mile taxi ride is 1.5 m + 3
Answer:
The answer is D
Step-by-step explanation:
- The resulting number is smaller than the original. This is true because if you take 20 times 0.5 it will equal ten. A decimal is pretty much a fraction in another form.
- The reason why A is false is because if the number isn't being multiplied by 1 then it can't stay the same.
- The reason why B is false is because that is not true as in the example above, 20 times 0.5, it equaled 10 and not less than one.
- The reason why C is false is because the the resulting number simply cannot be higher than the original when being multiplied by a decimal smaller than 1.
Hope this helps

There can’t be one formed because all sides of a triangle add up to 180 but when you add that it adds to 190 there for it will not make a triangle

Product means that u have to multiply the values so it will be 289*7 so it will be 2023
