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

Chem deposited $115.00 in a savings account. Each week thereafter, he

Yanka [14]

Answer:

Part a) $y=35x+115$

Part b) $\$1,165$

Step-by-step explanation:

Part a)

Let

x -----> the number of weeks

y ----> the total amount Chem has deposited in a saving account

we know that

The equation of a line in slope intercept form is

$y=mx+b$

where

m is the rate or slope of the linear equation

b is the y-intercept of the linear equation or initial value (value of y when the value of x is equal to zero)

In this problem we have that

The rate or slope is equal to

$m=35\frac{\$}{week}$ -----> amount deposited by Chem each week

The y-intercept or initial value is

$b=\$115$ ----> amount deposited originally in the saving account

substitute the values

$y=35x+115$

Part b) How much has Chem deposited 30 weeks after his initial deposit?

For x=30 weeks

substitute in the equation

$y=35(30)+115$

$y=\$1,165$
