Answer: 3, 4, -4
If you multiply those 3, it equals -48. When you add them together, it's 3.
A) is counting down by 3
B) is counting up by 5
Sqrt(49)*sqrt (-1) -4 = 7i-4
Whole-wheat bread = $2.06/lb
We need the cost of 3.8 lbs of whole-wheat bread.
So, we simply need to multiply the cost with the amount needed.
(cost per pound) × (amount of bread)
($2.06) × (3.8)
Simplify.
$7.828
Round to the nearest tenths.
$7.83
So, 3.8 pounds of whole wheat bread costs $7.83

x+y=8 and 25x+10y=170 are the linear equations.
x+y≤8 and 25x+10y≤170 are the inequalities.
Step-by-step explanation:
Given,
Worth of coins = $1.70 = 1.70*100 = 170 cents
Number of coins = 8
1 quarter = 25 cents
1 dime = 10 cents
Let,
x represent the number of quarters
y represent the number of dimes
1. Write an equation to represent the amount of coins Karen has.
x+y = 8
2.Write an equation to represent the value of the coins Karen has.
25x+10y=170
x+y=8 and 25x+10y=170 are the linear equations.
For inequalities, the amount cannot increase number of coins and worth but it can be less, therefore,
x+y≤8
25x+10y≤170
x+y≤8 and 25x+10y≤170 are the inequalities.
