n = d + 3
5n + 10d = 150 cents
Substitute to solve for "d":
5(d+3)+10d = 150
15d + 15 = 150
15d = 135
d = 9 dimes
n = d+3 = 9+3 = 12 nickels
So 12 nickels!!

Answer:
1 toast costs $0.30 and 1 egg cost $0.60
Step-by-step explanation:
Let price of 1 egg be and price of 1 toast be
<u>"$1.50 for 2 eggs and one piece of toast":</u>
We can write
<u>"$.90 for one egg and one piece of toast":</u>
We can write
Now, we can solve the first equation for t and substitute that into 2nd equation and solve for e:
Now using the value of e (0.6) and putting it back in the first equation, we will get t:
Hence, 1 toast costs $0.30 and 1 egg cost $0.60
Answer: Both calculated the volume properly.
Step-by-step explanation:
The formula for calculate the volume of a cylinder is:
Where <em>r</em> is the radius and <em>h</em> is the height.
You know that the radius of the cyclindrical swimming pool is 13 feet and the height is 6 feet.
Substitute these values into the formula. Then, the volume is:
or
Therefore, both calculated the volume properly.
