(7*10^x)+(7*10^y)+(7*10^z)=700070.0 7
write all possible set of values for x, y, z with the working.
plz

The answers are:

(x,y,z)=

(5,1,-2)

(1,-2,5)

(-2,5,1)

(5,-2,1)

(-2,1,5)

(1,5,-2)

Step-by-step explanation:

In order to determine the answer, we have to express the final number into a addition.

The number 700070.07 may be written by:

700000+70+0.07

Then, we can express every number into a scientific notation,that is, at the form:

700000

a=7

b=5

70

a=7

b=1

0.07

a=7

b=-2

So, in this case, we have three numbers: 5, 1, -2. The set of values are the combination of these numbers, in total 6 set of numbers.

Finally, the possible set of values for x, y, z are:

(5,1,-2)

(1,-2,5)

(-2,5,1)

(5,-2,1)

(-2,1,5)

(1,5,-2)

what is the question here

step-by-step explanation:

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
