Answer:
m = -2
Step-by-step explanation:
Since 10 is smaller than 12, we have to subtract to get a negative number.
10 - 12 = -2
Answer:
12
Step-by-step explanation:
(×-8)5=20
(5×-40)=20
5×(-40+40)=(20+40)
5×=60
5×÷5=60÷5
×=12
You just divide the distance travelled by the time like so: 145mi/2.5h and get 58mph. You can convert the 145mi into meters and 2.5h into seconds (145mi is approximately 233345m; 2.5h is 9000 seconds) and get an approximate speed of 26m/s if you want to convert to SI units.
