Answer:
150 pennies were lost altogether
Step-by-step explanation:
Let the initial number of pennies owned by Dante be x pennies
Let the initial number of pennies owned by Mia be y pennies
Mathematically ;
x + y = 350 •••••••(i)
So after losing half, dante will have x/2 pennies left.
Mia lost 1/3 so she will have 2/3y left
So after all the losses, they both had equal amount of pennies
This means that;
x/2 = 2y/3
Cross multiply;
3x = 4y •••••••(ii)
Let’s solve both equations simultaneously;
From i , x = 350-y
Substitute this into equation ii
3(350-y) = 4y
1050-3y = 4y
7y = 1050
y = 1050/7
y = 150
since x = 350-y
x = 350-150 = 200
Now Dante loss x/2 = 200/2 = 100
Mia lost 1/3y = 1/3 * 150 = 50
Total pennies lost = 100 + 50 = 150

Answer:
10 (X+1)
Step-by-step explanation:
Length = 2x + 5
Width = 3x
Perimeter of rectangle= 2(L + W)
P= 
P= 
Now, taking 5 as common
P= 
∴ Perimeter of rectangle= 
She boils 500 L of water and makes 80 grams, we are being asked to covert and solve for how many grams of pasta she will make if she boils 2500 mL.
The first think we need to do is convert 2500 mL to how many Liters.
2500 mL = ? how many liters.
2500 ml = 2.5 liters
Now, we need to set up a proportion to see how many grams we can make if we boiled 2.5 liters of water.
Set up a proportion.
500/80 = 2.5/x
First, we cross multiply.
500*x = 80*2.5
500x = 200
Now, divide each side by 500 to solve for x.
500x/500 = 200/500
x= 0.4
Final answer: Margo can make 0.4 grams of pasta if he boils 2500 mL of water.
