Answer:
D
Step-by-step explanation:
Let the number be represented by x
2x=60+ 5x -20*2=60+5*-20
2x-5x=5x-5x+60 -40=60+-100
-3x=60 -40=-40
-3x/-3=60/-3
x=-20
Therefore the number is -20
Answer:


This means that the family must travel for at least 4 days.
<em></em>
Step-by-step explanation:
Given


Required
Determine and solve the inequality
The number of days is represented with D
So:
On any D number of days, the family would have covered a distance of 350 * D miles
If the total distance is at least 1400, then the inequality is:

[The term "At least" is used to represent <em>greater than or equal to</em>]

Divide through by 350



<em>This means that the family must travel for at least 4 days.</em>
