Question

I need to perform the indicated operations. Round the result to the specified decimal place, when indicated...-3(0.2)-2(3.3) over 30(0.4)^ I have done it for the past hour and cannot come up with the right answer, either that or the answer in the back of the book is not correct. PLEASE help

Answer 1

Just to make sure we're on the same page:\[\frac{-3\cdot0.2-2\cdot3.3}{30\cdot0.4^1}\]

Answer 2

Is that correct?

Answer 3

The 30 on the bottom is 30 X 0.4 squaredr

Answer 4

What do you mean by squaredr? \[30\cdot0.4^2\]?

Answer 5

yes sorry keyboard issues

Answer 6

Ok, well 0.4^2=0.16 and 0.16*30=4.8

So we have 4.8 in the denominator

Answer 7

-3*0.2 -2*3.3 = -0.6 - 6.6 = -7.2

So -7.2 on top.

Answer 8

which gives -7.2/4.8=-1.5
