Answer:
2.8+.55x=5 x=4
Step-by-step explanation:
5-2.8=2.2
2.2/.55=4
P = 6
Q = 15
How to solve:
Note the equal sign. This means that both expression's out come must equal each other. For that to happen, everything inside both expressions must equal each other. In this case:
6x + Q = Px + 15; 6x + 15 = 6x + 15
hope this helps
Answer: p = 42
The bottom chord is 21+21 = 42 units long. This bottom chord is 11.2 units away from the center. Any other chord the same distance from the center will have the same length. The top chord has the same length of 42 units as it is also 11.2 units from the center.
First you set up the problem- 7/12=x/100. then you cross multiply 7×100=700 then divide 12 into 700 so 700÷12=58.333333333333 and so your percentage is 58.3%
