Answer:
9 mile/ 1 hour
Step-by-step explanation:
Because the squirrel ran 9 miles in 1 hour, so u have to divide 9 miles by 1 hour.
4.2x - 1.4y = 2.1 |multiply both sides by 10
42x - 14y = 21 |subtract 42x from both sides
-14y = 21 - 42x |change signs
14y = 42x - 21 |divide both sides by 14
y = 3x - 1.5
Answer:
6m + 2
Step-by-step explanation:
To simplify the expression you must have to use the distributive property:
