Answer:
There are calculators for these things, you know! You can look one up!
The cost of each duck is $ 7 and cost of each chicken is $ 12.
Step-by-step explanation:
Given,
5 chickens and 3 ducks are bought by $ 81
A chicken costs $ 5 more than a duck.
To find the cost of each duck and cost of each chicken.
Let,
The cost of each duck = x
The cost of each chicken = x+5
According to the problem,
5(x+5)+3x = 81
or, 5x+25+3x = 81
or, 8x = 81-25
or, 8x = 56
or, x = 7
Hence,
The cost of each duck = $ 7
The cost of each chicken = $ 7+5 = $ 12
You can find the slope of a line by looking at the number that has an X next to it.
for example
y=2x+5
the slope is = 2
hope this helps
Answer:
DISCLAIMER:I'M NOT REALLY GOOD AT MATH
Surface area=¶r squared.

=78.5
Answer:
the first bullet, M+0.15m
Step-by-step explanation:
Think about it this way:
M is the total amount of money you pay for the meal.
0.15m is the tax calculation, 0.15 x M= a 15% tip
Because a tip means added money on top of the total cost of the meal, you have to add both of them together.
