3x-4 = -10

3x-4 +4 = -10 +4

3x = -6

then you can divide it :

x = -6 : 3

x= -2

What is the difference between the exact simple interest and the ordinary simple interest on a 200-day loan of 5,000 at 12%
77julia77 [94]

Answer:

  4.56

Step-by-step explanation:

"Ordinary" interest will be more than "exact" interest because the number of days in a year is a smaller value. The difference will be ...

  Io = Prt = 5000(0.12)(200/360) = 333.33

  Ie = Prt = 5000(0.12)(200/365) = 328.77

The difference is ...

  333.33 -328.77 = 4.56 . . . the difference in interest values

_____

<em>Additional comment</em>

The question asks for the difference between exact and ordinary interest, so the result is technically negative:

  328.77 -333.33 = -4.56

Which number can each term of the equation be multiplied by to eliminate the fractions before solving ? -3/4 m-1/2=2+1/4mA 2B 3C
bixtya [17]

The correct answer is C. 4.

Typically, we look to multiply by the bottom number (the denominator) in order to get fractions to cancel out. If we multiply 1/6 by 6, we get just 1, which is why we do it.

In this problem, you have two different denominators, 2 and 4. If you multiply them all by 2, the term -3/4m will still be a fraction.

-3/4m * 2 = -3/2m

As a result, we must try 4 instead. This causes all of them to cease being a fraction. Even the one with 2 as a denominator.

-1/2 * 4 = -2

A rectangular patio has a perimeter of 44 feet. If the length of the patio is 5 feet less than twice the​ width, find the dimens
valentinak56 [21]
ANSWER: L=13; W=9
--Please read this explanation and this will be much easier for you, it took time to type..

Set up variables first. I will lead through how to get the answer.

First get variables. So, what is Perimeter? Perimeter is like so:

P = 2L + 2W = 44ft
Now instead of using P, we'll continue with

2L + 2W = 44 because this can be used to help answer the question better than P.

"Length of the patio is 5 ft less than twice the width"

So it says "length of the patio", so we put

L =

"5 ft less than twice the width"

L = 2W - 5

Now we know what L is, and we can plug this in to our first equation!

2L + 2W = 44
L = 2W - 5

Multiply by 2...
2L = 4W - 10

Plug in...
4W - 10 (2L see?) + 2W = 44

Rearrange...
4W + 2W - 10 = 44

And solve...
=6W - 10 = 44
=6W = 44 + 10
=6W = 54
=6W/6 = 54/6
=W = 9

Now we have W. Plug this into our other equation.

L = 2W - 5
L = 2*9 - 5
L = 18 - 5
L = 13

The length of the patio is 13 ft and the width of the patio is 9 ft.
