Answer:
The distance between Key's house and the amusement park is 1150 miles.
Step-by-step explanation:
In order to solve this question we can attribute a variable to the distance between Key's house and the amusement park, this variable will be called 'x'. Since this distance, that we want to know, is 100 times greater than the distance between James's house and the library that is 11.5 miles we can express it by the following equation:
x = 100*11.5 = 1150 miles
Answer:
Laura = 14 Years
Juan = 21 years
Step-by-step explanation:
Let :
Laura's age = x
Juan's = x + 7
Product of their ages = (x) * (x + 7) = 294
x² + 7x = 294
x² + 7x - 294 = 0
x² + 21x - 14x - 294 = 0
x(x + 21) - 14(x + 21) = 0
(x + 21) = 0 or (x - 14) = 0
x = - 21 or x = 14
Age can't be negative
Hence, x = 14
Laura = 14 years
Juan = 14 + 7 = 21 = 21 years
24=K•9
So then the next step is to divide by 9 on both sides to cancel the 9 out so you get the K alone.
24 = K•9
— ——
9 = 9
That cancels out the 9 by the K so now it’s
24
— = K
9
Now divide 24%9 and it’s 2.6666 but you round it to the nearest tenth so your answer is (2.7 = K)
