Answer:
5 erasers.
Step-by-step explanation:
0.35e + 0.15p = 2.80
e + p = 12
e = 12 - p
0.35(12 - p) + 0.15p = 2.80
4.2 - 0.35p + 0.15p = 2.80
4.2 - 0.2p = 2.80
-0.2p = -1.4
-0.2p/-0.2p = -1.4/-0.2
p = 7
e = 12 - 7
e = 5
<span>Answer: a) Greater than or equal to 38 feet
b)Since there is no restriction on the perimeter there exists many possible values for the length of the deck.
Explanation: Given that the width of the deck is 29 ft.
and the perimeter of the deck is at least 134 ft.
134 = 2(length + width)
134 = (2 x length) + (2 x 29)
134 = (2 x length) + 58
2 x length = 134 - 58
2 x length = 76
length = 76 / 2
length = 38 ft
Thus, the inequality will be:
a)Length ≥ 38 ft
b)since there is no restriction on the perimeter there exists many possible values for length of deck.</span>
You cannot solve this. TO solve both variables you need to have two equations. Please insert that equation in and I will solve this problem. :)
Answer:
#UseSimplifiedExpression
Step-by-step explanation:
(I don't know what your question is, but if you're asking about the rate, I got it.)
Answer: 2.6666... meters per second
Explanation/Calculation:
Divide 40 by 15 to get the rate. You get 2 2/3 meters or 2.6666... meters per second.
Hope this helps! :)
