The formula for calculating your credit utilization ratio is pretty straightforward. To figure it out for an individual card, divide your credit card balance by your available credit line.

What you you do is divide the credit card ratio for each one.

For the first card: $2,397 (total on card) divided by 16,000, (the limit) is 0.149, we round that to 0.15. (15%)

For the second card: $1,218 (total on card) divided by 5,500 (the limit) which is 0.221. We round that to 0.22. (22%)

The question asks for the OVERALL, and that means to add. 22+15=37.

What is 24 − 6 × 3 + 52 − (16 ÷ 2)?

Answers

Answer:

23

Step-by-step explanation:

When answering expressions like these we should always go by the order of operation. That order tells us to do parentheses, exponents, multiplication/division, then addition/subtraction. So as it said we will do whatever is inside the parentheses which is 16 ÷ 2.

24 − 6 × 3 + 5^2 − (16 ÷ 2)

24 − 6 × 3 + 5^2 − 8

Next is the exponent.

24 − 6 × 3 + 5^2 − 8

24 − 6 × 3 + 25 − 8

Now we will do multiplication/division.

24 − 6 × 3 + 25 − 8

24 − 18 + 25 − 8

Lastly we'll do addition/subtraction.

24 − 18 + 25 − 8

6 + 25 - 8

31 - 8

23

And that's it we got it!

24 - 6 x 3 + 52 - (16/2)= 50 !

What value is true of x makes this equation true 0.7x-5=0.2x+1

Answers

Answer:

x=12

Step-by-step explanation:

First you make sure x is on both sides of the equation. So you do 0.7x-5-0.2x=0.2x+1-0.2x. Which just simplifies to 0.5x-5=1. You make sure x is the only thing on that side of the equation so you do 0.5x-5+5=1+5 which simplifies to 0.5x=6. Multiply the equation times 2 to just have x. x=12. The value that makes true of x is 12.

What is the equation of the line that passes through the point (2, -2) and has a

Answer:

Step-by-step explanation:

use the point-slope formula [y-y1 =m(x-x1) ] with the given info

for the point P=(x1,y1) =(2,-2) and the slople m = -1/2

plug those into the formula

y-(-2)= -1/2(x-2)

y+2= -1/2x + 1

y= -1/2x+1 - 2

y = -1/2x - 1

A. 21
B. 77
C. 91
D. 115
E. 143

Hint : Use Wilson's Theorem[tex].[/tex]​

Answers

Answer:

C. 91

Step-by-step explanation:

Rewriting the given as factors:

12! · 6! + 12! + 6! + 1 =12!(6! + 1) + (6! + 1) =(12! + 1)(6! + 1) =((13 - 1)! + 1)((7 - 1)! + 1)

As per Wilson's theorem, if n is prime number, (n - 1)! + 1 is divisible by n

As per above, 13 and 7 are both prime numbers, so the expression is divisible by both 7 and 13:

7*13 = 91

So correct choice is C

How can I tell that a graph is a function or not?

Answers

Answer:

You can use the vertical line test, which means anywhere you put it on the graph it should only pass through the line once.

Step-by-step explanation:

This insures that the graph does not have two of the same x values. However if it has two points that have the same x values that means it will not be a function.

I hate math

First thing's first, PEMDAS. There's nothing to solve in the parenthesis, and there are no exponents, so use multiplication next. 6 • (x-2) and -8 • (x-3)

Your equation after should be

5x + 6x - 12 - 8x + 24

Next would be addition, don't forget it's always left to right.

11x - 12 - 8x + 24

Subtract twelve from the total (or in this case just from 24, and then add the remaining values (that are possible).

11x - 8x + 12

Next, subtract the two remaining x values.

3x + 12

And there you have it. Easy peasy.

If the case is trying to find x, just solve it like this.

3x = -12

x = 4
