Answer: the answer would be B :)
The answer is opposites apex. I hope this helps
The general pattern that these diamonds follow is that the top number is the result of multiplying the numbers in the middle; while the bottom number results from adding these numbers. This pattern can be used to find the numbers in the fourth diamond. Moreover, the numbers that complete the diamonds are A (15,8), B (2,-3), C (4,2), D(4,8.5), E (-3.-4)
<h3>What is the general pattern in the diamonds?</h3>
Based on observation, you can determine in these diamonds the top number is obtained by multiplying the numbers in the middle, while the bottom number is obtained by adding these numbers.
<h3>What numbers complete the diamonds?</h3>
Diamond A
Top number: 15 (3x5)
Bottom number: 8 (3+5)
Diamond B
Top number: 2 (-2x-1)
Bottom number: -3(-2+-1)
Diamond C
4, 2 because 4x2 = 8 and 4+2 = 6
Diamond D
Top number: 4( 8x0.5)
Bottom number: 8.5(8+0.5)
Diamond E
-3,-4 because -3x-4= 12, and -3+-4= -7

Then, distance of route passes the beach = x
Let the distance of route that passes the park = x+2
So, their sum would be: x+x+2 = 2x+2
So, option C Is your answer.......
Answer: The cost of 16 pencils and 10 notebooks is $5.84.
Explanation: You can solve this using linear systems:
Let X be the cost per pencil, and let Y be the cost per notebook.
(1) 7x+8y=4.15
(2) 5x+3y=1.77
Choose a variable to eliminate. I’ll eliminate X first as an example. To eliminate a variable, you must have the same coefficient beside the variable for both equations.
Equation 1 now becomes:
(3) 35x+40y=20.75
Equation 2 now becomes:
(4) 35x+21y=12.39
Now that you have 35 as a coefficient for X in both equations, you can subtract the two equations to officially eliminate it!
(3)-(4)
19y=8.36
y=0.44
Now that you have the value of Y, substitute that value into either one of the equations to get X.
Substitute y=0.44 in (1)
7x+8(0.44)=4.15
7x+3.52=4.15
7x=0.63
x=0.09
Therefore, the cost per pencil is $0.09/pencil and the cost per notebook is $0.44/notebook.
Almost done lol...
To find the cost of 16 pencils, multiply 0.09*16. That gives you $1.44, which will be the cost of 16 pencils.
The cost of 10 notebooks is 0.44*10, which gives you $4.40. That’s the cost of 10 notebooks.
To find the total price, add these values together!
1.44+4.40=5.84
Therefore, the cost of 16 pencils and 10 notebooks is $5.84.
Hope that helps シ
