Answer:
x = 2
Step-by-step explanation:
Given
5x - 4 = - 3x + 12 ( add 3x to both sides )
8x - 4 = 12 ( add 4 to both sides )
8x = 16 ( divide both sides by 8 )
x = 2
Answer:
(2n)*(n-1)
Step-by-step explanation:
Event A: The sum is greater than 5.There are 10 sums equal to 5 or less. Therefore there are 26 sums greater than 5.P = 26/36
Event B: The sum is divisible by 4.The sums that are divisible by 4 are the<span> three</span> 4's, five 8's, and the <span>one </span>12.That means there are nine sums divisible by 4. P = 9/36
Answer:
It will take 17.5 minutes to reach 50 degrees F.
Step-by-step explanation:
Current temperature = -13 degrees F
With the engine on, the temperature goes up by 3.6°F per minute.
Let us assume that it takes x minutes to reach 50 degrees F.
So, the time taken will be =

=> 
=> 
x = 17.5 minutes
The expression that tells how much the temperature needs to change from -13°F to 50°F is : 
It will take 17.5 minutes to reach 50 degrees F.
