The pythagorean theorem equation is a^2 (a squared) + b^2 (b squared) = c^2 (c squared)
so a^2+b^2=c^2
1/7(1000) = 1/7(7000/7)
1*7000
7*7
7000
49
1000
7
so 1/7(1000) = 1000/7 or 142 6/7
1: multiple both sides by 2
Ex:-7n+10=-32
2: subtract 10 from both sides
Ex: -7n=-42
3:divide both sides by -7 to get n alone
Ex: n=6
Answer is 6 and the process is elimination!
Celsius, Fahrenheit, Kelvin? One’d colder than the other. Unless ur looking for a detailed answer lol.
