Answer:
x = 7°
Step-by-step explanation:
3x° - 53° = x° + 67°
2x° = 14°
x° = 7°
The time(h), would be the independent variable and the temperature(C) would be the dependent variable.
Answer:
81
Step-by-step explanation:
If a number is divisible by 11, then you can make those numbers by multiplying 11 by any number. Like 33 is divisible by 11 because 3×11 is 33.
Of course, 33 is too small, we are looking for 3-digit numbers...
see image.
Remember that exponentioal rule
x^m times x^n=x^(m+n)
therefor
7^4 times 7^-6=7^(4-6)=7^(-2)
remember the other rule
x^-m=1/(x^m) so
7^-2=1/(7^2)=1/49
