Answer:
The equation for the distance Jane's trainer bikes is
.
Step-by-step explanation:
We have attached diagram for your reference.
Given:
Distance traveled on bike towards south = 16 miles
Distance she ran towards west = 12 miles
We need to find distance Jane's trainer bikes.
Solution:
Let the distance Jane's trainer bike be 'x'.
Now we will assume it to be right angled triangle.
So by Pythagoras theorem which states that;
"Square of the third side is equal to the sum of square of the other two sides."
framing in equation form we get;

Hence the equation for the distance Jane's trainer bikes is
.
On solving we get;

Hence Jane's trainer bikes a distance of 20 miles.
Answer:
The cost for each pound of chocolate chips is $2.75 and the cost for each pound of walnuts is $3.75.
Step-by-step explanation:
9x+7y=51
3x+5y=27
----------------
9x+7y=51
-3(3x+5y)=-3(27)
-------------------------
9x+7y=51
-9x-15y=-81
-------------------
-8y=-30
8y=30
y=30/8
simplify,
y=15/4
9x+7(15/4)=51
9x+105/4=51
9x=51-105/4
9x=(204-105)/4
9x=99/4
x=(99/4)/9
x=(99/4)(1/9)=99/36
simplify
x=2.75
So the cost for each pound of chocolate chips is $2.75 and the cost for each pound of walnuts is $3.75.
1 yard=3 feet so 100 yard=300 feet
