Step-by-step explanation: if you divide 27/30 by 3 you get 9/10
But 37 is not a factor of 3, in fact it is a prime number so anything that is divisible by it (other than 1) will be a decimal. So, my friend here you have another person on this app telling you that it is not 3 and is in fact 3.2432 (;;;
Answer:
\frac{2x^2}{3} =24
Step-by-step explanation:
times both sides by 3
2x²=72
divide both sides by 2
x²=36
sqrt both sides
x=+/-6
x=-6 or 6
-6<6 so -6 is the smallest solution
Since inches are out of 12 this would be
4 ft - 1 ft = 3 ft
3' 1" - 1 " = 3 '
3 feet is also 2 ft and 12 inches
2' 12" - 9 " = 2' 3"
So the answer is 2 feet and 3 inches
Hope this helps
