Step-by-step explanation:
sumthin like that.
|t + 4| < 10 - 3
|t + 4| < 7
-7 < t + 4 < 7
-7 - 4 < t < 7 - 4
-11 < t < 3.
Answer:
B
Step-by-step explanation:
-2 + 12 = 10
All the angles should add up to 360°.
8x+10x+9+21x-12+90=360°
Group like terms together.
So,8x+10x+21x+9+90-12=360
39x+87=360
39x=360-87
39x=273
x=7
Answer: Time = 1.5hours or 1 hour 30minutes
Step-by-step explanation:
Given;
Carrie can inspect a case of watch in 5 hours
if n represent the task,
Carrie's rate C = n/5
James' rate J = n/3
Their combined rate is=n/5 + n/3 = 8n/15
Carrie After working one hour, he would have completed n/5 of the task.
Therefore, the remaining fraction of task is 4n/5
To complete the remaining fraction of task by the two of them, the time taken can be given as;
Work done = rate × time
Time = workdone/rate
Workdone = amount of task remaining = 4n/5
rate combined= 8n/15
Time = (4n/5)/(8n/15)
Time = 1.5hours or 1 hour 30minutes
