Answer:
3
Step-by-step explanation:
The answer is 3 because 3 pounds would equal $23.31.
$46.69 (what she had left) plus $23.31 (the 3 pounds she bought) = $70.
Answer: 2.96 pounds of coffee.
$70-$46.96=$23.04
$23.04/$7.77=$2.96
So she bought 2.96 lbs worth of coffee. (If you need it to be rounded it would be 3.00 lbs)
2×9n=18n
2×-6=-12
52-12+18n= 38 +18n
2×7n=14n
8×2=16
14n+16
38+18n=14n+16
subtract 14n from 14n and 18n
38+4n=16
subtract 38 from 38 and 16
4n=-22
divide each side by 4
n= -5.5
4=4
m= -3
You should do m = -1 - 2 x 1 - 0 which equals m = -3
