Question

Peanuts worth $4/kg were mixed with almonds worth $6/kg to produce 12 kg of nuts worth $62.
Represent the unknowns above using the variables x and y.

Answer 1

so let, peanuts = x and almonds = y

Answer 2

the idea with these kind of questions is to form two equations and work them out simultaneously, so we know that a mix of peanuts and almonds = 12kg, as such we can see that
12kg = a certain amount of peanuts and a a certain amount of almonds
or in other words
12kg = a certain amount of peanuts + a a certain amount of almonds
12kg = x +y

Answer 3

understand?

Answer 4

awesome got it Thanks

Answer 5

u still need to figure out the second equation :)

Answer 6

is the other equation 4x+6y=12(62)

Answer 7

i did the first one and now ill guide u through with the second one :)

Answer 8

4x + 6y = 62 is the second equation :)
because $62 = $4 times the amount of peanuts (x) + $6 times the amount of almonds y =)

Answer 9

I see. Thanks
