Answer:
Monica has 3 more pieces of gold than silver after she cut all her wire
Step-by-step explanation:
Total length of gold wire Monica has= 7.68 meters
Length of each piece Monica wants to cut the wire into = 0.96 meters
Total number of pieces she can cut = = 8 pieces of gold wire
Total length of gold wire Monica has = 7.45 meters
Length of each piece Monica wants to cut the wire into = 1.49 meters
Total number of pieces she can cut = =5 pieces silver wire
Gold wire pieces= 8
Silver wire pieces= 5
Difference in the number of pieces =

Answer:
Her average speed is 48 miles per hour.
Step-by-step explanation:
We solve this question using a system of equations.
The speed equation is:
In which s is the speed, d is the distance, and t is the time.
Gabriella drives her car 320 miles and averages a certain speed.
So
Then
If the average speed has been 6 miles less she could have traveled only 280 miles in the same length of time.
So, which s - 6, d = 280.
From the first equation:
Replacing:
Her average speed is 48 miles per hour.
