Answer:
-7
Step-by-step explanation:
Given data
Tina's problem is
-16 - (-9)
Firstly let her open up the bracket
Note - * -= +
-16+9
Secondly, Rearrange
9-16= -7
Hence the answer is -7
Answer:
The width of the room is 17.25 feet
Step-by-step explanation:
2(15.75+W)=66
Divide both sides by 2: 15.75+W=33
Subtract 15.75 from both sides: W=33-15.75=17.25
Hope this helps!
2x-7=9
Add 7 to both sides
2x=16
Divide both sides by 2
x=8
Final answer: The number is 8
Answer:
8 hours
Step-by-step explanation:
In 2 hours, the clerical secretary can do 1/4 of the job. (The executive secretary does 3/4 of the job - or 3 times as much - in the same 2 hours.)
Since it takes the clerical secretary 2 hours to do 1/4 of the job, it will take them four times that to do it themselves. 2x4=8.
