A car averages 20 miles per gallon. If gas costs $2.12 per gallon, what is the closest amount to how much the gas would cost for this car to travel 2,757 miles?
We first need to establish how many times this car will need to stop for gas during our 2,757 mile trip. Since the gas tank will run empty every 20 miles, we will do 2,757 ÷ 20. This gives us 137.85. We will need to round up to 138 for this question. From here, we know that the car will need to stop 138 times. From there, we multiply $2.12 by 138, which gives us a total of $292.56.
What is the value of 5a + 2b when a = 2 and b = 7?
Since we know that a = 2 and b = 7, we can then plug in these known numbers ( 2 and 7 ) to our variables ( a and b ). From here, we have (5 x 2) + (2 x 7). Using our order of operations, we know that multiplication comes before addition. With this, we have 10 + 14, which gives us 24. Therefore, 5a + 2b = 24 when a = 2 and b = 7.
