Which value of x makes the equation 0.5(x + 15) = 2 + 0.75(x - 4) true?
SIZIF [17.4K]

Answer:

Step-by-step explanation:

\frac{1}{2}(x+15) = 2 + \frac{3}{4}(x-4)

To make this easier, to get ride of the fractions, we can multiply both sides by 4

2(x+15) = 8 + 3(x-4)

now use the distributive property

2x + 30 = 8 + 3x - 12\\

now we want to isolate x to one side and isolate all the constants to the other

2x - 3x = 8 - 12 - 30\\

now simplify

-x = -34\\x = 34

to test, we can plug in back to the original

\frac{1}{2}(34+15) = \frac{49}{2}\\\frac{8}{4} + \frac{3}{4}(34-4) = \frac{8}{4} + \frac{90}{4} = \frac{98}{4} = \frac{49}{2}

it works

Rafael takes home $4200 per month. What is the maximum amount he can
galben [10]

Answer:

A bad debt ratio of more than 10% is considered high and often is a sign that you are in danger of credit overload. So, I'd $420 is the maximum amount he can spend on credit card payments and loan each month.

Step-by-step explanation:

Let's clear this with an example:

Rafael makes $4,200 a month and let's say he spends $550 on credit card payments and $450 on an loans.

Then, the ratio calculation would be $1000 / $4,200 = 0.24

Multiply that by 100 for a debt-income-ratio of 24%.

In this example, Rafael spends almost a quarter of his income on debt which is considered bad debt in economics.
