divide both sides by a
subtract b from both sides
multiply all terms on both sides by -1
c=b-d/a
400 pages in 5 days
but 120 on the first day
so 400-120=280
280 is what he read in the 4 days following
so divide 280 equally among the 4 days
You get 70 per day after the first
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.
The defensive area is 510 square yards
Step-by-step explanation:
Let L be the length of the rectangle
and
W be the width
According to given statement
L = 2W-15
Perimeter = 270
Dividing both sides by 6
We have to find the area first to find the defensive area
So,
Defensive area = 3/25 of total area
So,
Hence,
The defensive area is 510 square yards
