Mrs. Eaton sometimes makes melon salad for events. she ​made it a couple months ago, she used 2 kilograms of honeydew melon 2 kilograms of watermelon, which cost her $4. today she used 1 kilogram of honeydew melon and 2 kilograms of watermelon, spending a total of $3 on the melons. ​​Assuming that the prices of the melons haven't changed, how much does a kilogram of each type of melon cost?

180 square centimeters

step-by-step explanation:

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

thats not a system of equations, that is a solution
