Answer:
The difference between - 4 1/2 and -1 is -3 1/2
—4 1/2 --(—1)
— 4 1/2 + 1
— 3 1/2
Step-by-step explanation:
x - 2/3 = 5/6
the only step needed is to add 2/3 to 5/6
2/3 + 5/6 = 1 1/2
x = 1 1/2
Set up two equations:
1st: P (for Price family) + J (for Jenkins family) = 45 hours
2nd: 20P + 35J = 1200 liters
Rewrite the first equation as P = 45 – J
Replace P in the second equation:
20(45-J) + 35J = 1200
Simplify:
900 -20J + 35J = 1200
900 +15J = 1200
Subtract 900 from both sides:
15J = 300
Divide both sides by 15:
J = 300/15
J = 20
Jenkins used theirs for 20 hours
Price used theirs for 45-20 = 25 hours.
A is the answer for the question
The constant of proportionality is 3.50 since gummy worms are sold at the same rate per pound.
3.50x, equation
3.50(2.5) = $8.75 for 2.5 pounds
