Answer:
6
Step-by-step explanation:
X+y=4
2x+y=6
make first equation negative
-x-y=-4
add to first equation
2x-x+y-y=6-4
x=2
subsitute
x+y=4
2+y=4
y=2
or
x+y=4
subtract x from both sdies
y=4-x
subsitute 4-x for y in second equation
2x+4-x=6
x+4=6
x=2

Step-by-step explanation:
1.19 dollars/quart x 1 quart/ 32 ounces = .037 = 3.7 cents per ounce
when you set up the multiplication, since quarts are in the denominator initially and you want to get rid of them, set the quarts in the numerator of the unit rate (1 quart/ 32 ounces) so that the units cancel and you are left with the units that you wanted ($/ounce).
Clear as mud?! :)
