Answer:
Midpoint coordinates are 
Step-by-step explanation:
The Coordinates of R = (-8,3)
The Coordinates of S = (9, -7)
Let M be the mid point of M and its coordinates by (x,y)
Now, by mid point formula,

⇒
So, the midpoint coordinates are 
Answer:
(1, -2)
Step-by-step explanation:
1 < -|-2|
1 < |2|
because its absolute x can be -2 or +2. Both are greater than 1 so absolute 2 gets eaten.
Answer:
720 pennies
Step-by-step explanation:
Initially the Penny bank is 1/2 full
After removing 120 pennies it is 1/3 full;
Therefore. the fraction equivalent to 120 pennies is;
1/2 -1/3 = 1/6
Thus; Assuming the number of pennies that the penny bank can hold when full is x; then;
1/6 of x = 120
x = 120 × 6
= 720 pennies
Hence, when the penny bank is full it can hold 720 pennies.
Answer:
x=64
y=40
Step-by-step explanation:
2x+x-12=180
3x=192
x=64
3y+y+20=180
4y=160
y=40
