The answer is B. 21 + b = 30
Answer:
3 friends played golf
Step-by-step explanation:
33-12=21
21/7=3
You end with 210.85. add 75.50 and 55.25 together you get 130.75. 130.75-25.15-18.65 = 86.95. 210.85-86.95= 123.90 work backwards.
Answer:
(9, 6)
Step-by-step explanation:
<u>Midpoint formula is:</u>
- x = (x₁ + x₂)/2
- y = (y₁ + y₂)/2
<u>Having coordinates of one end- and midpoint </u>(-5, 12) <u>and</u> (2, 9)<u>:</u>
- x₁ = -5, y₁ = 12
- x = 2, y = 9
<u>we get the coordinates of the missing endpoint with coordinates</u> (x₂, y₂):
- x₂ = 2x - x₁ = 2*2 - (-5) = 4 + 5 = 9
- y₂ = 2y - y₁ = 2*9 - 12 = 18 - 12 = 6
<u>So the missing point is</u>: (9, 6)
Answer:
-3 and -9 are the roots.
