In this question, we're trying to find cost of one sandwich.
To find this, we must make a systems of equation from the given information:
We would represent sandwiches as "s" and drinks as "d".
Systems of equations:
6s + 4d = 53
4s + 6d = 47
Solve for s:
6(6s + 4d = 53)
-4(4s + 6d = 47)
36s + 24d = 318
-16s - 24d = -188
--------------------------
20s = 130
Divide both sides by s
s = 6.50
This means that one sandwich costs $6.50
Answer:
$6.50
Two dozens and you have one shell left
Answer:
0.95 miles per minute
19 miles in 20 minutes
Step-by-step explanation:
To find out how many miles traveled in a minute, we will divide 57 by 60, because there are 60 minutes in an hour, and there were 57 miles traveled in a hour. This gives you the rate of miles per minute (0.95), and to get the answer for 20 minutes, just multiply 0.95 by 20 (19 miles).
The equation that represents the amount of soil, s in cubic centimeters the ferret can dig from the burrow in m minute is as follows:
s = 93m
One of the ferrets digs 465 cubic centimeters of soil from a burrow in 5 minutes.
The digging rate can be calculated as follows;
<h3>What is rate?</h3>
A rate is a ratio between two related quantities in different units. Therefore,
rate = 465 / 5 = 93 cubic centimetres per minutes.
Therefore, the equation that represents the amount of soil, s in cubic centimeters the ferret can dig from the burrow in m minute is as follows:
