There were 20 erasers added to each box, because 15 plus 20 is 35. 85 plus 20 is 105, and 35 times 3 is 105. This means that there are 35 erasers in box B after adding 20, and 105 erasers in box A after adding 20. I hope this helps you!
Answer:
F=3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(6−f)−4=3f−4
(3)(6)+(3)(−f)+−4=3f+−4(Distribute)
18+−3f+−4=3f+−4
(−3f)+(18+−4)=3f−4(Combine Like Terms)
−3f+14=3f−4
−3f+14=3f−4
Step 2: Subtract 3f from both sides.
−3f+14−3f=3f−4−3f
−6f+14=−4
Step 3: Subtract 14 from both sides.
−6f+14−14=−4−14
−6f=−18
Step 4: Divide both sides by -6.
−6f−6=−18−6f=3
Answer:
f=3
Given :
A meat market sells fajitas for $5.12 per pound.
To Find :
The cost of 3 - lbs of fajitas.
Solution :
Price of 1 pound fajitas, p = $5.12 .
So, price of 3 pounds of fajitas is :
P = 3 × p
P = 3 × 5.12
P = $15.36
Therefore, price of 3 pounds fajitas is $15.36 .
