Jamie says the value of the expression 1.43 × (−
16

31
) is close to −0.75. does jamie's estimate seem reasonable? explain.

jamie's estimate reasonable. the product of the expression is and about half of .

Jamie's estimate is reasonable.

Explanation:

The expression is

Dividing the term , we get,

Multiplying the terms, we have,

But, Jamie's estimate is

The difference between the two values is which is negligible.

Hence, Jamie's estimate is reasonable.

hello from mrbilldoesmath!

(x^2-9)/ (x + 3) = x-3

you,

mrb

hope this !

let me know
