Answer:
(x+7)÷5
Step-by-step explanation:
since the number is unknown, it becomes X. Because we first add 7 then divide by 5, the expression will be a bracketed (X+7), followed by the division by 5. This makes sense because of the BODMAS rule to which, in coherence with the BODMAS rule, we first solve the expression in the brackets then move on outside them.
X/2 means 1/2x
To delete the denominator multiply for 2. You have to multiply also 17 for 2 since you have half x.
2*1/2x = 17*2
x = 34
Answer D.
It depends on what the graph shows. I need to see the graph to help you. sorry
Answer: 95metres for the length and the original cost is 2.105
Step-by-step explanation:
Let the initial length be x,
So, x+5=200/2
x+5=100
x=95
Note since the total price is the same and the original length is 95metres.
Therefore, the original cost per metre is
200/95=2.105
