Step-by-step explanation:
<span>x = 9
Since ZP bisects â OZQ, that means that the measurements for â OZP and â PZQ are the same. So create an equation with their respective values set to each other.
8x - 9 = 5x + 18
Now solve for x
8x - 9 = 5x + 18
Subtract 5x from both sides
3x - 9 = 18
Add 9 to both sides
3x = 27
Divide both sides by 3
x = 9</span>
Answer:
Any from 1:3.5 , 4:14 , 6:21 (etc) would be equal to 2:7
Step-by-step explanation:
2 divided by 2 would be 1, and 7 divided by 2 would be 3.5. 2 times 2 = 4, and 7 times 2 = 14. 2 x 3 = 6, 7 x 3 = 21 (etc).
