Take out the division by bring 5 to the other side. (5x5). then bring the 3 over (-3 turns into +3). then divide by 2 to isolate n. final answer 14.
2n-3= 5x5
2n-3=25
2n=25+3
2n=28
n= 28÷2
n=14
Answer:
Step-by-step explanation:
i think its a 1/3 probability as a circle adds up to 360 degrees and if you add 60 and 60 it equals to 120.
120/360 as a simplified fraction=1/3
Since she answered 90% of her quiz correct, that means if she were to answer 10 questions, 9 would be correct. Lucky for us, 50 is a multiple of 10. If you multiply 10 by 5, you'd get 50. You would also need to multiply 9 by 5 as well. When you do this you'd get
45/50 correct. (divided them to make sure you get .90 if so, I'm right :)
Answer:
For the first one the diameter is 22. Circumference is 69.08. Area is 379.94
Second question is radius is 12. Circumference is 75.36. Area is 452.16
Step-by-step explanation:
Radius = d/2
Diameter = r*2
Circumference = 3.14*d
Area = r^2*3.14
