Answer:
$2 per Chicken and $9 per Duck
Step-by-step explanation:
the equations for the problem are as follows (x = the value of chickens and y = the value of ducks):
5x + 3y = 55
4x + 3y = 53
if you subtract the equations you would get x = 2, which means the chickens are worth $2 each
If we re-input the x that we now know as 2 and solve one of the equations for y, we will get y = 9
The inequality that represents the number of text Heather can send is 30+0.05t≥60
Answer:
Her grocery bill is $4.62
Step-by-step explanation:
The first step is to multiply 6 and .43 to get how much it was for all of the apples.
Then the next step is to do the same thing with the oranges.
Then the last step is to add the two together.
If neighborhood A has 30 homes and increases by 20% each year, we first need to multiply 30 by 20%, which is 6. Next, add the six new houses to the original 30, which is 36. If neighborhood B has 45 homes, but gets three more, that is 48. After one year, neighborhood B has more homes than neighborhood A. Neighborhood A will have more houses than neighborhood B after 4 years. (Five years if you count the starting year.)
