Step-by-step explanation:
increass by +2,+3,+4,+5,+6
Let
x---------> Steve's time
y--------> Paul's time
we know that
------> Steve is faster than Paul

<u>the answer is the option</u>
A. Steve is 5⁄6 as fast as Paul
Answer:
f ≥ -2
Step-by-step explanation:
6f ≥ -12
Divide both sides by 6;
f ≥ - 2
Answer:
x = -2
y = 10
Step-by-step explanation:
(0.3 + 0.7) x + (0.4 - 0.8) y = 0.8 - 6.8
x - 0.4 y = -6 → x = 0.4 y - 6
0.3 ( 0.4 y - 6) + 0.4 y = 0.8 → 0.12y +0.4y - 1.8 = 0.8
→ 0.52 y = 2.6 → y = 2.6/0.52 = 10
x - 0.4(10) = -6 → x = -2
