Answer:
Try 5 first. If that is marked wrong, try 5.07
Step-by-step explanation:
Estimate means put your calculator on the other side of the room. You are to do this in your head.
78 is nearly 80
69 is nearly 70
29 is nearly 30
So now do the question
80 + 70 = 150 because 8 and 7 = 15.
150 / 30 = 50 because 15/3 = 5
So the answer that should be right for this question should be 5
Let's see how close that is.
78 + 69 = 147
147 / 29 = 5.07
Answer:
a would be 12
Step-by-step explanation:
because there are 5 1's so you would subtract 5 from 65 and get 60 and divide 60 by 5 and get 12
Hope this helps!!! Mark me as brainiest!!!!! :)

When W(t)=30
Because the fraction 2/5 can't be simplified
