A contractor buys 16 and 3/10 tons of sand and uses 8 and 4/5 tons. how much sand is left?

9,3/10

Step-by-step explanation:

16-8=8

4/5-3/10=13/10 or 1,3/10

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
