Answer:
3h
Step-by-step explanation:
let time be x
total distance = 450
75x+75x=450
150x=450
x=3h
In this case, you aren't going to get an integer for the value of a, but you can rearrange the equation to equal a.
4a-3=D add 3 to both sides
4a=D+3 divide both sides by 4
a=(D+3)/4 here's your answer
X is less than or equal to -4 (couldn’t find the symbol)
0,-5 i hope this is can sorry if its wrong
If I understand the question, you have to get n alone. in this case, you have to subtract 7 from both sides, resulting in n (is less than) -10
