Answer:

<h2>Hello!!!</h2>

Step-by-step explanation:

The first step for solving this expression is to remove the first set of parenthesis.

-8.3x+4 - (3.2x-5)

Remember that when there is a "_" sign in front of the parenthesis, we must change the sign of the expression to the following

-8.3x + 4 - 3.2x + 5

Collect the like terms with an x variable.

-11.5x + 4 + 5

Lastly, add the number to get your final answer

-11.5x + 9

Hope that helps you dear...

Have a nice day..

Buhbye!

Log4(x^2 + 6x +8) - log4 ( x+2)

vaieri [72.5K]

Since the logarithms have the same base, we can simply divide (x^2 + 6x + 8) by (x+ 2) and just retain the sme base. So, the answer will be Log4(x+4)

3x + 18.45 = 1850.00

elixir [45]

Answer:

$\frac{1831.55}{3}$

Step-by-step explanation:

Subtract 18.45 from each side: 3x = 1831.55
Divide each side by 3 to cancel out the 3 next to x. It should now look like this: $x = \frac{1831.55}{3}$

I hope this helps!

What are the dimensions of this rectangle?

Sholpan [36]

Answer:

F:53cm by 102cm

Step-by-step explanation:

The perimeter of a rectangle can be seen as 2l + 2w, with the length being l, and the width being d. If the ratio is 3:2, then 3+2= 5 parts would be the sum of the length and the width, This is half of the perimeter 2(l+w), so 510÷2 = 255. One part would be 255÷5=51.

If you put it into the ratio, effectively it is:

Length:Width

3×51:2×51

153 :102

Therefore the dimensions are 153cm by 102cm, which is F.

Marc is running 5 kilometers at track practice. He decides to break the run into 3 equal lengths. How long will each length be?

MrMuchimi

Divide 5 by 3.
If you do this on a calculator you will get 1.666666667.
You will then round that to 1.7
Because "4 or less let it rest, 5 or more raise the score"
