When 0.3(4x – 8) – 0.5(–2.4x + 4) is simplified, what is the resulting expression?

vitfil [10]

Answer: 2.4x−4.4

Step-by-step explanation:

0.3(4x – 8) – 0.5(–2.4x + 4)

1.2x−2.4−0.5(−2.4x+4)

1.2x−2.4−(−1.2x+2)

1.2x−2.4+1.2x−2

(1.2x+1.2x)+(−2.4−2)

2.4x−4.4

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great rest of Black History Month! :-)

hi if anyone is good with extraneous solutions pleaseeeeeee help meeee tessa solves the equation below by first squaring both si

Sergio [31]

Answer:

x = -7/5

Step-by-step explanation:

If we square both sides of the equation, we get:

$\sqrt{x^2-3x-6}=x-1\\ (\sqrt{x^2-3x-6})^2=(x-1)^2\\x^2-3x-6=x^2-2x+1\\$

Then, solving for x, we get:

$x^2-3x-6=x^2-2x+1\\-3x-6=2x+1\\-6-1=2x+3x\\-7=5x\\\frac{-7}{5}=x$

So, x is equal to -7/5

A garden table and a bench cost $1000 combined. The garden table costs $100 more than the bench. What is the cost of the bench?

bogdanovich [222]

Let $x be the cost of the bench, then $x+100 is the cost of the table
x+x+100=1000
2x=900
x=450
So the cost of the bench is $450
