Answer:
P - 4
Step-by-step explanation:
Sergio and the other painting collectors have decided to donate a total of 48 paintings all together.
We know that there are 12 collectors in total and they will each donate the same number of paintings.
48 paintings in total
12 collectors
48 / 12 = 4
We now know Sergio will donate 4 paintings from his collection of P paintings. Sergio will have P - 4 paintings left.
We do not know what "P" is equal to, so we cannot give an exact number for how many paintings he will have left. However, we know he will have 4 fewer paintings after donating.
5x + 3y= 8.50
3x + 2y= 5.25
Lydia is the first equation. She bought 5 pounds of apples which is x and bought 3 pounds of bananas which is y. Basically, remember each banana and apple weighs a price per pound. We don't know the price so we just put an x. This is the same for the second equation
Her school is 2/3 miles away
2/3=4/6miles
So we need to find out how long it will take for her to run home from school...
School=4/6 miles
In 1 minutes she can run 1/6 miles
1min=1/6miles
In 2 minutes she can run 1/6+1/6 miles (1/6+1/6=2/6)
2min=2/6miles
3min=3/6miles
4min=4/6miles
It will take Erica 4 minutes to run 4/6 miles, so it'll take her 4 minutes to get home.
