HELPPP MEEE PLZZ ok so If i have 70$ dollars the amout is just right so i can buy 4kg of fish and 3kg of prawn so i bought it and my change was $3.50 How much is 1kg of prawn?

x = (66.50 - 4y) / 3

Step-by-step explanation:

Given that:

Amount had = $70

Change collected = $3.50

Total amount spent = $(70 - 3.50) = $66.50

Total amount used for purchasing prawn and fish:

Kg of fish = 4

Kg of prawn = 3

1 kg prawn will cost, x

If 1 kg of fish = y

(Total amount spent - cost of 4 kg fish) / Number of kg of prawn

($66.50 - 4y) / 3

x = (66.50 - 4y) / 3

answer: 0,6

step-by-step explanation:

this would make it the y intercept.

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
