You start by changing the fraction into a decimal.
4.5 lb. of ground beef= 16.11
6.25 lb. of ground turkey= 18.50
Next, you divide the amount they cost by the pounds to get the price per pound.
16.11÷4.5= 3.58
18.50÷6.25= 2.96
So, a pound of beef is $3.58, and a pound of turkey is $2.96.
The turkey is 62 cents less than the beef per pound.
That means the turkey is a better buy! :)

Answer:
544
Step-by-step explanation:
The statement 8.5 times the difference between 77 and 13 can be expressed mathematically as 8.5×(77-13)
According to BODMAS, we will deal with the expression in the bracket first to have;
8.5×64
Then we the product of the resulting expression.
8.5×64
= 544
The answer is 544
Answer:
x^2 -x -2 = (x -2)(x +1)
Step-by-step explanation:
To factor x^2 -x -2, you look for factors of -2 that have a sum of -1:
-2 = (-1)(2) = (1)(-2) . . . . . the latter pair has a sum of -1
Then these are the constants in the binomial factors:
x^2 -x -2 = (x +1)(x -2)

<em>Comment on the question</em>
The fact that x^2 +3x -4 is modeled with algebra tiles seems to be irrelevant to the question that is actually asked.
Answer:
20% increase
Step-by-step explanation:
All you have to do is divide 72 by 90n and it will give you .8, move the decimal two places to the right to give you 80 and subtract 80 from 100 to get 20
