Answer:
around 8 or 8.5 miles a day for 7 days
Step-by-step explanation:
60 divided 7 equals 8.5
Magnitude of vector V =√(3²+7²) = √58
Hence: U= -3/√58 - 7/√58
OR multiply numerator and denominator by √58
U = - (3√58)/58 i - (7√58)/58 j
Oof I had that question and I was so stuck on it I still dont know it till this day ah life is hard
Answer:
10xy-5
Step-by-step explanation:
15xy-4+2xy-7xy-1 is the given expression.
I assume the directions say to simplify.
Group the xy terms together and group the constants together.
15xy+2xy-7xy-4-1
This is a demonstration of the commutative property.
Now I will use the distributive property to rewrite the first 3 terms as a multiplication:
(15+2-7)xy-5
10xy-5
It would be 28-10=x because your ending up with 28 after earning 10 you would get that. Hope this works!
