Repeating decimal I think
Answer:
its 8
Step-by-step explanation:
Trevor rents the car for 3 days and there’s a $23.95 fee per day, so that would already add up to $71.85. If you subtract the $71.85 from your $100 budget you will have $28.15,and now you divide that by .25 because it’s 25 cents per mile and all you have left is $28.15 and you will get 112.6,but the whole miles Trevor can drive are 112
Since you are given a list of choices, you can go through each choice to plug them into the equations. It turns out that choice B is the answer
(3,1) means that a = 3 and b = 1
Plug in a = 3 and b = 1 into the first equation
2a - 5b = 1
2*3 - 5*1 = 1.... replace 'a' with 3, replace b with 1
6 - 5 = 1
1 = 1
we get a true equation, so we have confirmed the first equation
Do the same for the second equation
3a+5b = 14
3*3+5*1 = 14 .... replace 'a' with 3, replace b with 1
9+5 = 14
14 = 14
we get a true equation, so the second equation has been confirmed
Both equations are true when (a,b) = (3,1). So the answer (3,1) has been confirmed fully
