the sum of the digits of two digit number is 10. when 18 is added to the number is digit reversed find and number​
Contact [7]

Answer:

<em>The number is 46</em>

Step-by-step explanation:

<u>Equations</u>

Suppose:

a = One digit of the number

b = Tens digit of the number

The sum of the digits is 10:

a + b = 10

The number expressed as two-digits quantity is ab, and its value is

10a+b

When we add 18 to that number, we have:

10a+b+18

And that is represented as the number reversed:

10a+b+18=10b+a

Simplifying:

9a+18=9b

Dividing by 9:

a + 2 = b

Substituting in the first equation:

a + a + 2 = 10

2a = 8

a = 4

b = a + 2 = 6

Thus the number is 46

I need help! Will mark brainliest!
Musya8 [376]

Answer:

16) 6%

17) 4 years

18) 2 years

Step-by-step explanation:

The formula for these questions is I = PRT

16) 27 = 900 (R) (0.5)

Notice how I used 0.5 instead of 6 for the T. T has to be measured in years, not months and 6 months is half a year.

R = 0.06 = 6 %

17) 480 = 2000 (0.06) (T)

T = 4 years

18) 1080 = 4500 (0.12) (T)

T = 2 years
