The answer is b. Great job! here ill show you the work.
15x +90 > 270
move constant to the right side and change its sign, like this:
15x>270-90
then subtract the numbers
15x>180
lastly, divide both sides by 15.
hope this helped!
Hmm they're both even numbers so maybe we can start by cutting each number in half.

18 and 48 had 2 as a common factor.
So factoring a 2 out of each number was the same as cutting each number in half. Try to do something similar with the 9 and 24. They each have something in common.
Answer:
Lake Michigan and Lake Huron
Step-by-step explanation:
Lake Michigan and Lake Huron - two of North America's Great Lakes - are contiguous and they share the same elevation of 577 feet above sea level. They are connected by the five-mile-wide Straits of Mackinac. Hydrologically, this makes these "two lakes" a single lake.
Some hydrologists designate the combined entity of Lake Michigan and Lake Huron as "Lake Michigan-Huron."
The square root of any number is the same as that number to the 1/2 power
root(b)=b^(1/2)
Max has X, and as Keisha has four more,
Keisha is 4+x
The total amount is x+x+4
2x+4
