Lets look at the info we have:-
Ashley found 78 rocks on Monday.
Devin found 45 rocks on Tuesday.
Question:-
How many did they find both days?
The key word for this is "both". So we need to add here. Lets add:-
78 + 45 = 123
So, Ashley and Devin together found 123 rocks.
Hope I helped ya!! xD
A point is a geometry figure named with lowercase letters (I'm pretty sure)
You’re answer is y=-1/1.5x+2.5
Explanation
2.5 is you’re y intersect and you go over one < and up 1.5
The answer is one, because the number seven in the hundredths column is greater than five so you round the nine up to 1.0.
