Answer:
$21.85
Step-by-step explanation
the equation would be
4.95b+3.50c
b= the number of books (3)
c= the number of candles (2)
plug in the numbers
4.95(3)+3.50(2)=21.85
Create an equation: x*(x-3)=14
5.53112887 and 2.53112887
You can round the numbers and get 5.53 and 2.53
4(-x + 4) = 12
-4x + 16 = 12
- 16. -16
-4x = -4
/-4. /-4
x = -1
That’s what I got. First get rid of parentheses, next subtract 16 on both sides, then divide by -4 to get x by itself and there’s your answer -1
