Answer: Ian would have drove 91 miles using only 3 gallons of gas.
Step-by-step explanation: I used paper and pencil and used a T-chart putting one section at the top “gallons” and the other “miles”; under gallons I put 7 because the question stated with “7 gallons of gas”; under miles I put 217 because the question states that with 7 gallons of gas Ian’s car travels 217 miles so using the T-chart I want to simply the 7 gallons of gas to one gallon of gas to figure out how miles Ian’s car would go only using 3 gallons of gas; by dividing 7 by 7 giving me 1, and with a T-chart you wanna do the same thing to both sides meaning I divided 217 by 7 as well giving me 31 for 1 gallon of gas, meaning Ian’s car would travel 31 miles with only using 1 gallon of gas. After I find that answer I go to multiply the 1 under “gallons” by 3 to and again, if you do it to one side you have to do it to the other meaning I multiplied 31 my 3 as well; giving me 91. Meaning with only using 3 gallons of gas Ian’s car would travel 91 miles!

Answer:
She'll receive $6.53.
Step-by-step explanation:
First add everything she purcahsed.
1.22 + 1.48 + 7.98 + 2.79 = 13.47
Then subtract that from how much she paid.
20 - 13.47 = 6.53
So 6 dollars and 53 cents.
Answer:
Step-by-step explanation:
<u>Equation for this case is:</u>
⇒ y = 6(x - 1) + 10 as Rs. 10 for the first km and Rs. 6 for the rest (x - 1) km
⇒ y = 6x - 6 + 10 simplifying
⇒ y = 6x + 4 final equation
<u>For x = 15 km we have total of:</u>
Answer:
x = 75
Step-by-step explanation:
Assuming the angles are equal ( bisected means divided in half)
2x-5 = 145
Add 5 to each side
2x-5+5 = 145+5
2x = 150
Divide by 2
2x/150/2
x = 75
