Erin ran 3 1/2 more lap then last week with a total of 12 this week. to solve divide 30 by 2 1/2 and then subtract 8 1/2
Answer:
2x - 3 = 11
Step-by-step explanation:
"difference" means subtraction, so it is subtraction.
"twice a number" simply means 2x, since you do not know what the specified number is, it is x. and the 2 and just making it twice the number.
"Is 11" just means equals 11.
so, 2x - 3 = 11.
hope this helps!
