Answer:
A
Step-by-step explanation:
Equation
2x + 3x + 8 + 7x - 2 = 90
Solution
Combine like terms on the left
12x + 6 = 90 Subtract 6 on both sides
12x = 90 - 6
12x = 84 Divide by 12
x = 84/12
x = 7
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."
U have to simplifie that problem.
