What is 2/5 y + 1/5 x -0.2y-6+(-2)

Step-by-step explanation:

1)  Simplify 2 /5y to 2y/5.

2) simplify 1/5x to x/5.

3) Collect like terms.

4) Simplify.

Therefor, the answer is y/5 + x/5 -8.

answer: 230 miles ( vote ! )

step-by-step explanation:

180.39 minus 17.99 equals 162.4

then divide 162.4 by .80 to get 230

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
