Answer:
12+4y
Step-by-step explanation:
12+3y+y=12+4y
The unit rate for the graph above is 60 heartbeats per minute. Half of 2 is 1 so go to the 1 min. mark and go up until you reach the line graph and it says 60. Do the same for the 2 min. mark and go up until you reach the line graph and it'll say 120. 60 ÷60=1 and 120 ÷ 60= 2
The expanded form is adding all the digits so the answer is
700+50+7+0.9+0.02+0.003
