80 because of you cross multiply 6 times x and 30 times 16 you get 480 and 6 divided by 480 is 80
6/16=30/?
6x=480
Divided by 6
?=80
If you estimate
7 times 7=49 so the square root of 46 is less than 7
6 times 6= 36 so the square root of 46 is more than 6
so if you do it on a calculator the answer is 6.78
8 is the answer
