Answer:
The temprature change was +190 degrees farenheit
Step-by-step explanation:
subtract 290-100 using absolute value
This would be displayed as 11 - 5k
This cannot be solved, however, without knowing the value of k, or at least what the expression is equal to.
Step 1: LCM of 24 , 30 and 60 = 120
so 120 is the least no which is divisible by all 24 , 30 and 60
Step 2: factors of 120 will be 2^3 * 3 * 5
so the least perfect square, which is divisible by 24, 30 and 60 will be
(2^3 * 3 * 5) x ( 2 * 3 * 5 ) = 3600
