Answer:

$2x+10 \\\\or\\\\2(x+5)$

Step-by-step explanation:

in order to write an equivalent expression to -3x+5(x+2) we need to expand it and simply (sometimes factoring):

$-3x+5(x+2) =\\\\= -3x+5x+10 \\\\=5x-3x+10\\\\=2x+10$

and we can go further :

$2x+10=2(x+5)$

Hope this helps

Start by converting to like terms, so convert 1/2 to 2/4.

Next, look at the problem. You are adding a negative, which is the same as subtracting, so your new problem looks like this: 2/4 - 3/4.

If you take 3/4 from 2/4, you are left with -1/4. This is your final answer!

Answer:

1/18

Step-by-step explanation:

$( {2}^{ - 3} \times {16}^{ \frac{1}{2} } ) \div ( {81}^{ \frac{3}{4} } \times {27}^{ - \frac{1}{3} } ) \\ \\ =( {2}^{ - 3} \times {2}^{ \frac{4 \times 1}{2} } ) \div ( {3}^{ \frac{4 \times 3}{4} } \times {3}^{ - \frac{3 \times 1}{3} } ) \\ \\=( {2}^{ - 3} \times {2}^{ 2} ) \div ( {3}^{ 3 } \times {3}^{ - 1 } ) \\ \\=( {2}^{ - 3 + 2} ) \div ( {3}^{ 3 - 1 } ) \\ \\ = {2}^{ - 1} \div {3}^{2} \\ \\ = \frac{1}{2} \times \frac{1}{9} \\ \\ = \frac{1}{18}$
