Answer:
the first one
Step-by-step explanation:
0.0206×0.188<0.0769/0.000023
For this case we define the following variable:
x: time it takes A to perform the job separately.
We then have the following equation:
From here, we clear the value of x.
We have then:
Therefore, the time it takes for B to complete the work is:
Answer:
B will spend 12 hours doing that work separately
Answer:
-6m-54, and y-x
Step-by-step explanation:
1: if m is less than 9, and 9•6 is 54, then 6m -54 will be less than 54
that means it will be negative. so you take |6m-54| out of absolute value, and make it negative: -6m-54
2: for this one, y is greater than x, so the overall answer must be positive. remove the absolute value sign, but don't change the equation.
|y-x|=y-x
