From what I recall, just set both the equations equal to each other
6x=5x+7
6x=5x+7
-5x -5x
1x=7
x=7
Then just plug in what you found.
y=6(7)
y=42
y=5(7)+7
y=35+7
y=42
42=42
Thus, you know your answer is correct.
Step-by-step explanation:
area of rhombus =1/2(d1×d2)
=1/2(4.25×4.25)
=1/2×18.0625
=9.03cm^2

Answer:
140 oranges
Step-by-step explanation:
From the Question, we know that the pyramid has 7 layers
The number of oranges in the first layer is = 1
Hence, the number of oranges in a pile is calculated as:
1² + 2² + 3² + 4² + 5² + 6² + 7²
= 1 + 4 + 9 + 16 + 25 + 36 + 49
= 140 oranges
