Answer:

(11/7)x + (3/7)y

Step-by-step explanation:

Perform the indicated multiiplication. We get:

(6/7)x - (2/5)y + (5/7)y + (5/7)x

Now combine like terms, obtaining: (11/7)x + (3/7)y

An alternative expression would be (1/7)(11x + 3y)

Do 0.3 and 3.0 have the same value. Explain. Explain=10 points

just olya [345]

No, 0.3 and 3.0 do not have the same value. The zero in front the decimal point, means that the next digit has a value less than one. The first decimal position is greater than the second decimal position, and it is greater than the fhird decimal positio, and so on; 0.3 is 3/10. The digit 3 in 3.0 has value of 3 units which is greater than 3/10.
