The estimated total cost, y, of a child's toy is partially based on the number of batteries used,
the toy itself costs $12. which equation represents the situation?
the cost of one battery is $0.75.
y = 12x +0.75
y = 0.75x + 12
y = 12x - 0.75
y = 0.75x - 12

Step-by-step explanation:

: total cost

: number of batteries

If the toy costs $12, the total cost must be those $12 plus the amount of money spent in the batteries.

Money spent in batteries:

this is because each battery costs $0.75, is he uses amount of batteries he must pay the

Thus, the total cost is

which is the cost of the batteries and the cost of the toy added together.

the answer to this question is yes

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
