Answer:
I think it’s 7%
Step-by-step explanation:
<u>Answer
</u>
Option B) 7 is the correct answer
FD = 7cm
<u>Explanation
</u>
Here triangle AEC. D is the midpoint of EC and F is the midpoint of EA
So D and F be the midpoint of triangle AEC.
FD be the midpoint joining line.
We know that if any triangle, line joining the midpoint of two sides is the half of the third side.
Here the third side is 14cm, then FD = 14/2 = 7cm
So option B) is the correct answer.
Answer:
The cost of hardbook is $9 and cost of paperback is $5.
Step-by-step explanation:
Let x be the price for hardback book and y be the price for paperback book.
Mr. Yamamoto purchased 42 new hardcover books and 64 new paperback books, which cost a total of $698.
We can write the equation as:

He also purchased 42 new hardcover books and 58 new paperback books, which cost a total of $668.
We can write the equation as:

We have to use the elimination method to solve the two equations.
We eliminate x by subtracting the two equations.

Thus, the cost of hardbook is $9 and cost of paperback is $5.
Answer:
b = 76°
Step-by-step explanation:
Hi there,
It is important to know that the sum of all the angles in any triangle equals 180°.
For this problem, we can write the following equation:
32° + 72° + b° = 180°
104° + b° = 180°
b° = 76°
Hope my explanation helps. Cheers.
This problem is not easy but use division and multiplication
