Step-by-step explanation:
We have been given that one a recent trip, Cindy drove her car 290 miles, rounded to the nearest 10 miles, and used 12 gallons of gasoline, rounded to the nearest gallon.
The range of miles driven would be between
because number of miles in rounded to nearest 10 miles.
The range of gallons of gasoline would be
because number of gallons of gasoline in rounded to nearest gallon.
To find mileage, we will divide number of miles by number of gallons.
The possible number of gallons of gasoline will be 12.5 gallons for 285 miles to get the minimum number of miles.
Similarly, the possible number of gallons of gasoline will be 11.5 gallons for 295 miles to get the maximum miles.
Therefore, our required range would be
and

Whenever you add fractions it means you need a common denominator. The quickest way to find this number is to multiply the two denominators together (in this case 8 and 9).
So your new fractions are 63/72 and 32/72. When you add those you get 95/72.
Next simply divide the two numbers to get a decimal, so here we get: 1.31944...
So this number is closer to 1
Hope that helps!!
Answer:
lets say number = n and n = 24
so the answer is 24
and the whole answer to the question is 24 - 5 = 19
Step-by-step explanation: I love algebra and plz mark me brainlyiist :)
The angles are 27°, 27° and 126°
let the 2 equal angles be x then the third angle = 3x + 45
sum of 3 angles = x + x + 3x + 45 = 5x + 45 = 180
hence 5x = 180 - 45 = 135⇒ x= 135/5 = 27
the angles are 27°, 27° and 3x + 45 =81 + 45 = 126°
