D varies directly with t means
d=kt
105=3k
divide both sids by 3
35=k
d=35t
when t=8
d=35(8)
d=280
B
Approximate the real zeros of f(x) = x2 + 3x + 1 to the nearest tenth
<u>C. 2.6,-0.4</u>

Assuming it's 7, 2, and 31, you can set up (31+7)/2 is the amount that Carlos scored, which is 38/2 or 19.
Add (-2X) to both sides:
2X + B + (-2X) = C + (-2X)
If we (rearrange) it into B + 2X + (-2X) = C + (-2X)
B + 2X - 2X = C + (-2X)
Since +2X - 2X = 0
B + 0 = C + (-2X)
B = C + (-2X)
B = C - 2X
