Answer:
6 seconds
Step-by-step explanation:
Initial distance of Mario from motion detector = 2 ft
Speed of Mario = 1.5 ft/sec
Total distance of Mario from motion detector = 11 ft
Total distance moved by Mario while walking at the rate of 1.5 ft/sec = 11 - 2 = 9 ft
Given that:
Distance = 9 ft
Speed = 1.5 ft/sec
<em>Formula:</em>


So, at <em>6 seconds</em>, Mario will be 11 ft from the motion detector.
It looks like the terms are:
(7x2 + 5) and (x - 3)
Answer: 20d + 5
Step-by-step explanation:
First we need to combine like terms.
In this equation we can see that they're are 3 numbers containing the letter D we have -4, -4, 28.
We're going to combine -4 and -4 to get -8 and then combine -8 to 28 getting 20d
Afterwards we're going to combine 3, 2 equaling 5.
40 times 8 =320 Also 4 times 10 = 40 times 8 equal 320 30 times 10 equal 300. 5 times 60 = 300. 5 times 6 tens = 30 tens = 300
