The cost to the nearest sent is 0.14
This is because you can round the .136 up to the nearest hundredths place.
2x-y=3
use the substitution method
2(2)-y= 3
4-y= 3
move 4 to the other side
sign changes from +4 to -4
4-4-y= 3-4
-y= 3-4
-y=-1
mutiply both sides by -1 to get +y
(-1)(-y)= (-1)(-1)
y= (-1)(-1)
Answer: y= 1
a=-2, b=3, c=-4, d=5
abc-d
abc means multiply those 3 together
so -2 x 3 x -4 = 24
24-5 = 19
answer is 19
