What is 6.3-2(1.5c+4.1)
ASHA 777 [7]
Expand\;-2\left(1.5c+4.1\right)
\mathrm{Distribute\:parentheses\:using}: \:a\left(b+c\right)=ab+ac
\;a=-2,\:b=1.5c,\:c=4.1

Simplify\;-2\cdot \:1.5c-2\cdot \:4.1 \ \textgreater \  \mathrm{Multiply\:the\:numbers:}\:2\cdot \:1.5=3
-3c-2\cdot \:4.1

\mathrm{Multiply\:the\:numbers:}\:2\cdot \:4.1=8.2 \ \textgreater \  -3c-8.2 \ \textgreater \  6.3-3c-8.2

\mathrm{Subtract\:the\:numbers:}\:6.3-8.2=-1.9 \ \textgreater \  -3c-1.9

Hope this helps!

How is adding and subtracting decimals different from adding and subtracting whole numbers?
Monica [59]
It isn't different, it is very much the same
1-1 = 0
.1-.1 = 0
5.25 - 3.75 = 1.50
1.0005 +1.005 = 2.0055
just make sure to line the decimal places on top of each other <span />

Answer:

4 can be rewrite as 2•2, and that's the same as 2².

8 can be rewrite as 2•2•2, and that's the same as 2³

So we can rewrite the whole expression as:

2^x = (2²)⁸•(2³)⁴

2^x = 2¹⁶•2¹²

2^x = 2²⁸

So x = 28
