greater than
Step-by-step explanation:
7/8 is greater than 4/8
6 items for $14.34 each is $86.04.
So @mathmate deleted my comment because "I wasn't explaining my answer" well I did
I clearly stated that you have to make educated guess and I showed how I GOT my answer
so i guess here is my "proper" answer
There is no specific formula for this, so you can make an educated guess
for example:
13*5 = 65 (this isn't right because we need a minimum of 114)
so we continue the guessing
I then next tried
13*9
I got 117,
117 is more than 113
making 9 the minimum amount of rows for the hotel parking lot
there ya go @mathmate is that clear enough?
Answer:
1. The first problem is wrong, it should be 0.5(3(15) + 2(20)) because the parentheses make sure that every purchased item is being divided by 2 (multiplying by 0.5 is the same as dividing by 2)
2. The second problem is partially correct. The first two answers you have checked are correct, but the last one is wrong. The third answer should be 6 + 12 instead because that's just a simplified version of 2(3) + 6(2), meaning they are equal
3. I cannot read your answers in the "Why or Why Not" column in the third problem, but the answers you gave in the "Evaluate" and "Does It Work?" columns are all correct.
