First you need to subtract 750-600= 150.
Then 150 time .35=52.5.
Lastly 52.5+49.99= 102.49
Answer: 2014
Step-by-step explanation:
LED: -25x + 6y = 20
CFL: 15x + 2y = 322
we need to find which year it was the same to know where LED lighting surpassed CFL lighting
-25x + 6y = 20
15x + 2y = 322 (-3)
-25x + 6y = 20
<u>-45x - 6y = -966 </u>
-70x = -946
x = 13.51
The nearest year would be 14 which is 2014
The best way to solve this one is with a proportion:
(15 steps) / (5 minutes) = (75 steps) / ('x' minutes)
Cross-multiply the proportion: 15 x = 5 x 75
Divide each side by 15 : x = 5 x 5 = <em>25 minutes</em>.
You are correct, and Paul walks very slowly.
