Step-by-step explanation:
here's the solution: -
Average time taken by sarah :
=》

=》

=》

average time taken by sarah = 70.9 seconds
now,
average time taken by katie :
=》

=》

=》

average time taken by katie = 78.9 seconds
so, sarah is more efficient (faster) than katie.
i agree with sarah.
cuz, she took less time than katie.
Answer:
7.52
Step-by-step explanation:
5.37 + x = 12.89
In order to solve this equation, we must isolate the variable, x.
1.) To do this, subtract 5.37 on both sides of the equation.
5.37 + x = 12.89
-5.37 -5.37
x = 7.52
Therefore, x = 7.52
-4 _> 4(6y-12)-2y
first distribute/ simplify the equation
-4 _> 24y-48-2y
then combine like terms
-4 _> 22y-48
solve for y
-4 _> 22y-48
44 _> 22y
2 _> y
so the answer is y <_ 2 ( y is less than or equal to 2)
The answer will be <span>x + y = 6 </span>
