"Sum of 32 and 5 times a number " translates to:
(32 + 5) × n
Then, it says "is 17"
So, (32 + 5) × n = 17. Let's solve!
32 + 5 = 37
37 × n = 17
To find n, we just divide 17 by 37. However, that equates to a repeating decimal, so it is best to put the answer as:
Answer:
- <u>14.4 mile</u>²
Explanation:
1. By driving 6 miles each, the cars will be 6 miles + 6 miles = 12 miles appart.
2. When one car stops and the other car makes a 90° left-hand turn and drive 8 miles, you can model the situation with a right triangle, where one leg is 12 miles, the other leg is 8 miles, and the hypotenuse is the distance that separates the cars.
Hence, you must use Pythagoras to find that distance.
3. Pythagoras
- hypotenuse² = leg₁² + leg₂²
- hypotenuse = (12 mile)² + (8 mile)² = 144 mile² + 64 mile² = 208 mile²
, which is rounded to the neartest tenth of a mile.
