Answer:
see below
Step-by-step explanation:
6 1/2 = 6 + 1/2 *3/3 = 6 + 3/6
4 5/6
6 3/6
-4 5/6
-----------------
We need to borrow from the 6
6 3/6 = 5 + 6/6 + 3/6 = 5 9/6
5 9/6
-4 5/6
--------------------
1 4/6
We can simplify 4/6 to 2/3
Solution: 1 2/3
Answer:
Each envelope is $1.42
Step-by-step explanation:
Let, the cost of postcards = x and the cost of envelopes = y, in dollars.
It is given that,
First customer paid $12 for 14 postcards and 5 envelopes.
This gives, 14x + 5y = 12.
Second customer paid $24.8 for 10 postcards and 15 envelopes.
This gives, 10x + 15y = 24.8
We get the system of equations,
14x + 5y = 12
10x + 15y = 24.8
We multiply 1st equation by 3. This gives us the equations,
42x + 15y = 36
10x + 15y = 24.8
Subtracting both equations, we get,
32x = 11.2
i.e.
i.e. x = 0.35
Which gives,
10 × 0.35 + 15y = 24.8
i.e. 15y = 24.8 - 3.5
i.e. 15y = 21.3
i.e.
i.e. y = 1.42
Hence, the cost of each postcard is $0.35 and each envelope is $1.42.
Step-by-step explanation:
Find the 3rd angle in the triangle, let's call it y
36 + 73 + y = 180
109 + y = 180
y= 71
y is equivalent to x by vertical angles theorem
x= 71
2nd way
Use exterior angles theorem
180 - (36+73) = x
180 - 109 = x
71 = x
