Answer:
-12
1
9
13
Step-by-step explanation:
its just the numbers in front of the variables
First, change the fractions to a common denominator, which is 21.
so 3/7 * 3/3 = 9/21
1/3 * 7/7 = 7/21
Add the two together
9/21 + 7/21 = 16/21
Then take 21/21 - 16/21 = 5/21
There is 5/21 of the pizza left.
The general form is ax²+bx+c=0,
so at least we know b has to be 0. None of the values match unless we multiply everything by 4. That leads to answer B, a=1, b=0 and c=20
$0.58 + $0.58
$1.16
total cost of all 3 will be $1.16 since he only got two at the sale price
