Trial and error but that will take time so there is a formula for it hope this helps
Formatting first:
Step 1: (6.2 − 1.6) − 4.4 + 7.8
Step 2: 6.2 + (− 1.6 − 4.4) + 7.8 (commutative property)
Step 3: 6.2 − 6 + 7.8
Step 4: −14 − 6 = 8 (commutative property)
Step 5: 14 − 6 = 8
Step 2 is the associative property (a+b)+c=a+(b+c)
Step 4 is just wrong with -14 instead of 14; seems corrected in step 5.
Answer: He wrote commutative instead of associative in Step 2.
Answer:
90
Step-by-step explanation:
3/2(60) = 90
Explanation:
You can calculate angular velocity in radians per second by using linear units.
That should be correct
