This is the answer ,you should first do the multiplication then the sum.
Answer:
I think it is A but not 100% sure.
Step-by-step explanation:
Answer:
He drove for 1 hour and 30 minutes, and started driving at 12:45pm
Step-by-step explanation:
Firstly, you deduct 60 and 90. That means that he has been driving one hour, then the remainder is 30, which means that at the speed of 60mph he traveled that much in half an hour. Then you add the 15 more minutes to the time of the meeting (don't let this confuse you, don't try to add the 15 more minutes to the time that he traveled, but to the end time). That means that he drove for a total of 1 hour and 30 minutes. Now you just move the clock back from 2:15 pm for 1 hour and 30 minutes. That means that he started driving at 12:45 pm
(this confused me so much and I don't know why, but I hope I helped)

Answer:
about 14.7
Step-by-step explanation:
The 10 is the total amount so the equation would be 10=210-15t so the 10 would be the total the answer to the equation is..add 210 to 10 then divide 220 by 15t.
Answer:
Therefore the coordinate of P₂ is (-3,1)
Step-by-step explanation:
Mid point: The mid-point is a point from where the distance of the end points of a line segment is equal.
The co-ordinate of mid point of (x₁,y₁) and (x₂,y₂) is
Here x₁= -5 and y₁= 9
And the coordinate of the mid point is (-7,1).
Let the coordinate of P₂ be (x,y)
Therefore the coordinate of midpoint of P₁ and P₂ is
According to the problem,
and
Therefore the coordinate of P₂ is (-3,1)
