Answer:
D
Step-by-step explanation:
Using the midpoint formula to find the coordinates of Q
let the coordinates of Q = (x, y ), then
0.5(3 + x) = 2 ← equate to x- coordinate of M
Multiply both sides by 2
3 + x = 4 ( subtract 3 from both sides )
x = 1
and
0.5(9 + y) = 8 ← equate to y- coordinate of M
Multiply both sides by 2
9 + y = 16 ( subtract 9 from both sides )
y = 7
Thus the coordinates of Q are (1, 7 ) → D
Answer: 13+9 = 22

Answer:
3
Step-by-step explanation:
8 + 3 = 3 + 8
Order doesnt matter
The unit price of the first one which is a is 8 cents an ounce. The second one is 9 cents an ounce.
What you do is you take your price and divide it by the ounces.
