Answer:
Step-by-step explanation:
y = total cost of gas
x = gallons of gas
(a)
y = 1.60x
(b)
y = 1.60x
32.00 = 1.60x
32.00 / 1.60 = 1.60x / 1.60
32.00 / 1.60 = x
20 = x
x = 20
Trevor bought 20 gallons of gas.
Answer:
(x + 9) (x - 8)
Replace a with 9
and b with -8
Step-by-step explanation:
So 6 in pond
some on grass
# in pond+# in grass=14
6 in pond
subsitute 6 for pond
6+# in greass=14
subtract 6 from both sides
6-6+# in grass=14-6
0+# in grass=8
# in grass=8
there are 8 ducks in grass
so you would draw a circle for the pond and put 6 circles in there to represent the ducks, then , outside of that big circle, draw 8 circles to represent the 8 ducks on the grass (maybe label the big circle as pond and outside as grass)
