Question

BRANLIEST PLEASE HELPPPP What is the value of n? Enter your answer in the box. Circle with two intersecting chords forming an x shape in the circle. The top left side of the x shape is labeled n plus 1. The top right side of the x shape is labeled n plus 7. The bottom left side of the x shape is labeled 9. The bottom right side of the x is labeled 18.

Answer 1

Answer:  n = 5

Step-by-step explanation:

$\dfrac{n+1}{9}=\dfrac{n+7}{18}\\\\\\\underline{\text{Clear the denominator:}}\\18\bigg(\dfrac{n+1}{9}\bigg)=18\bigg(\dfrac{n+7}{18}\bigg)\\\\\\\underline{\text{Simplify and solve for n:}}\\2(n+1)=n+7\\2n+2=n+7\\n+2=7\\\large\boxed{n=5}$

Answer 2

Answer:

5

Step-by-step explanation:

• 9/(n+1)= 18/(n+7)
• 1/(n+1)=2/(n+7)
• n+7= 2(n+1)  cross multiplication
• n+7=2n+2
• 2n-n= 7-2
• n=5
