1kilogram of nuts costs $8 how much would 3/2 of a kilogram cost?

You can use cross multiplication. Note that 3/2 = 1.5

1kg .... $8

1.5kg .... $x

So we have,

3/2 kilogram of nuts costs $12.

Hope this helps.

step-by-step explanation:

do 6-10=

if u need it to be negative.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
