Answer:
The coordinates of the midpoint are;
(-6.5, -3)
Step-by-step explanation:
Here, we want to get the midpoint of the line segment
To get this, we use the midpoint formula;
(x,y) = (x1 + x2)/2, (y1 + y2)/2
Thus;
(x,y) = (8 - 21)/2, (-10 + 4)/2
(x,y) = -13/2 , -6/2
(x,y) = (-6.5 , -3)
Answer:
1. x=17.5
2. x=77
Step-by-step explanation:
1. -x=-3x+35
=2x=35
x=17.5
2. -x/7+8=-3
=-x/7=-11
=-x=-77
x=77
Answer
No missing money
Step-by-step explanation:
Original money given to the waiter = $30
Each person paid $10
The waitress comes back with the waitress comes back and said the bill is $25
They gave her $2 for the tip
if each got $1.00 back
Balance = $1.00 × 3
= $3.00
That means each paid $9×3 = $27 including $2 .00 tip(recall that cost of the meal is now $25 plus $2 tip)
Each of them got $1.00 back
Total money spent = (cost of meal + tip) + balance of $3.00 given to them
= $27 + $3
= $30
Therefore, there is no missing $1.00
The answer is 6 because 39/13=3 and 18/3=6
