Midpoint formula
Let S denote the midpoint of R and T
x with no number beside it simply means 1x
Answer:
x = 7
Explanation:
8 + 4 = 2 (x − 1)
Simplify both sides of the equation
8 + 4 = 2(x − 1)
8 + 4 = (2)(x) + (2)(−1) (Distribute)
8 + 4 = 2x + −2
(8 + 4) = 2x − 2 (Combine Like Terms)
12 = 2x − 2
12 = 2x − 2
Flip the equation
2x − 2 = 12
Add 2 to both sides
2x − 2 + 2 = 12 + 2
2x = 14
Divide both sides by 2
2x / 2 = 14 / 2
x = 7
Answer:
Hey there!
4^2-2(3(5)+1)
16-2(15+1)
16-2(16)
-16
C is correct.
Let me know if this helps :)
Just multiply 2 and 15 and you get 30. 30 miles is the answer
