Answer:
DP = 9/5
Step-by-step explanation:
DP + PE = DE
DP: x
PE: 4x + 7
DE: 10x - 2
x + 4x + 7 = 10x - 2
5x + 7 = 10x - 2
-5x = -9
x = 9/5
DP: 9/5
PE: 4(9/5) + 7
DE: 10(9/5) - 2
Check:
9/5 + 4(9/5) + 7 = 10(9/5) - 2
1.8 + 7.2 + 7 = 18 - 2
16 = 16

Answer:
The number of rooms that can be wire with available rolls is 6 rooms
Step-by-step explanation:
Given as :
The quantity of roll of electrical wire does electrician need = unit
Total quantity of wire rolls available = 4 unit
i.e Total quantity of wire rolls available = unit
Let The number of rooms that can be wire with available rolls = n rooms
<u>Now, According to question</u>
The number of rooms that can be wire with available rolls =
i.e n =
Or, n =
Or, n =
∴ n = 6
So, The number of rooms that can be wire with available rolls = n = 6 rooms
Hence, The number of rooms that can be wire with available rolls is 6 rooms . Answer
