Answer:

the slope is \frac{2}{5} and the y-intercept is 1

Step-by-step explanation:

if we can get it to y=mx+b form, then it's easy since the slope is m and the y-intercept is b

solve 2x-5y=-5 for y

2x-5y=-5

minus 2x from both sides

-5y=-2x-5

divide by -5 both sides

5y=\frac{2}{5}x+1

match

m=\frac{2}{5} and b=1

the slope is \frac{2}{5} and the y-intercept is 1

  • Compound number n = 1 (once per year)
  • Time t = 6 years

<u>Future amount formula:</u>

  • F = P(1 + r/n)^(nt)

<u>Substitute given values:</u>

25 is 45% of what number
Oksi-84 [34.3K]

Answer: 55.56

Step-by-step explanation:

Let the unknown number be k

(45 x k) / 100 = 25

45k/100 = 25

multiply both sides by 100

45k = 25 x 100

45k = 2500

divide both sides by 45

k = 2500/45

k = 55.56

Express 15.16 as a mixed number
kap26 [50]
If this is not a typo, and you mean 15.16 as in 15 and 16 hundredths, we can express this into a mixed number.
Mixed numbers are a whole number with the remainder of that number as a fraction.
For example, 1.25 as a decimal = 1 1/4 as a mixed number.
Since we already have our whole number, 15, we need to know what 16 hundredths is simplified as a fraction.
Currently, our mixed number is 15 16/100.
To simplify this, we need to find a common factor that 16 and 100 share.
Since they are both even numbers, let's divide by 2.
16/2 = 8
100/2 = 50.
Our new mixed number is 15 8/50.
Currently our fraction is still even, so divide by 2 again.
8/2 = 4
50/2 = 25
Your new mixed number is 15 4/25.
4 and 25 have no common factors, so the fraction is simplified.
Your answer is:
15.16 is 15 4/25 as a mixed number.
I hope this helps!
