Question 11 is C and also question 2 is A
V = d/t = 8.8 miles/[80/60] hours = 6.6 miles/hour
t = d/v = d/6.6
Answer: d/6.6, where d is the number of miles to run.
When you estimate, you round each number, the add.
We round them to
700+620, which is 1320
So our non estimated answer is 1323
But our estimated answer is 1320
Answer:r-1
Step-by-step explanation:
(-r-5)-(-2r-4) Or (-r-5)-(-2r-4)
-r+-5+2r+4. -r-5+2r+4
r-1 r-1
You bring down the first Parentheses Then have to multiply the (implied 1) -1•-2=2 and -1•-4=4 and do the math regularly
