Answer:
1/2 =x
Step-by-step explanation:
9/x + 2 = 20
Subtract 2 from each side
9/x + 2-2 = 20-2
9/x =18
Multiply each side by x
9/x *x = 18*x
9 = 18x
Divide each side by 18
9/18 = 18x/18
1/2 =x
We find the length of AD using the similarity of right triangle property. See image attached.
AD² = BD × CD
AD² = 9 × 36
AD² = 324
AD² = 18²
AD = 18
The length of AD is 18 units
Hey there!
a + 2 = 10
SUBTRACT 2 to BOTH SIDES
a + 2 - 2 = 10 - 2
CANCEL out: 2 - 2 because that gives you 0
KEEP: 10 - 2 because that helps solve for the a-value
10 - 2 = a
10 - 2 = 8
Answer: Option C. a = 8
Good luck on your assignment and enjoy your day!
