Answer:

5/x = 7/x-4

5(x-4) = 7(x)

5x - 20 = 7x

5x - 7x = 20

-2x = 20

x = -20/2 = -10

I need help. This just doesn't make sense
djyliett [7]

Answer:

x = 4

Step-by-step explanation:

BE bisects AD and AC, hence is a mid- line segment. Hence BE is half of CD

CD = 12 ⇒ BE = 6, that is

x + 2 = 6 ( subtract 2 from both sides )

x = 4 → C

If the total for this month's credit purchases is $550 at 24% annual interest, what is the total balance for the month after one
umka2103 [35]

Answer:

The total balance for the month after one month of interest accrues is $561 .

Step-by-step explanation:

Given as :

The principal credit in account = p = $550

The rate of interest = 24% annual

The time period = 1 month = \dfrac{1}{12} year

Let The Amount after one month of interest = $A

<u>Now, From Simple Interest method</u>

Simple Interest = \dfrac{\textrm principal \times \textrm rate\times \textrm time}{100}

Or, s.i = \dfrac{\textrm p \times \textrm r\times \textrm t}{100}

Or, s.i = \dfrac{550\times 24\times \frac{1}{12}}{100}

Or, s.i = \dfrac{13200}{1200}

Or, s.i = 11

∵ Amount = Principal + interest

So, A = s.i + p

Or, A = $11 + $550

∴  A = $561

So, The amount after one month on interest = A = $561

Hence, The total balance for the month after one month of interest accrues = A = $561 . Answer

Which of the following equations are true? Select all that apply.
patriot [66]

Answer:

none of them are true, but if you could re copy and paste and delete all of the spaces, I can make 100% sure because I could've did something wrong with it looking like this.

24.8/ 102= 0.243

34.65/ 1,000= 0.03465

193.5/100= 1.935

6.24/10= 0.624

160.4/ 102= 1.5725

these are the equations in the problem with their actual answers, none of them match the ones provided
