Answer:

B, E

Step-by-step explanation:

Given expression

-2.5(1-2n)-1.5n

First, use the distributive property:

-2.5(1-2n)-1.5n\\ \\=-2.5\cdot 1-2.5\cdot (-2n)-1.5n\\ \\=-2.5+5n-1.5n

Use distributive property once more:

-2.5+5n-1.5n\\ \\=-2.5+n(5-1.5)

So, option E is correct.

Now,

-2.5+n(5-1.5)\\ \\=-2.5+n\cdot 3.5\\ \\=-2.5+3.5n

Thus, option B is correct

Fantom [35]

Answer:

The answer is 180

Step-by-step explanation:

So to start off you have to turn 20% into a decimal and that is .20.

Next  you need to mutiply 225 and .20 and you will get 45 (that means it is $45 off)

Subtract 45 fro 225 and that is your answer.

You now pay $180 for the 20 foot extension ladder.

Write 0.0059 in scientific notation.
polet [3.4K]
Hi!

When we write a number in scientific notation, we write it like this:
N × 10^{x}

N = a number between one and 10
x = negative if the decimal is moved to the right. positive if moved to the left.

Okay, so we need to move the decimal in the number <span>0.0059 to the right to make it between one and 10.
0.0059
00.059
000.59
0005.9
5.9

N = 5.9
5.9 </span>× 10^{-x}

Since we moved the decimal to the right 3 times,
x = -3

5.9 × 10^{-3}
^ the answer

Hope this helps! :)
