Hello! :)

Answer:

\huge\boxed{751}

Let the smallest digit, or the units' digit, be equal to x:

Tens' digit is four more, therefore:

x + 4 represents the tens' digit.

Hundreds' digit is 2 more than the tens' digit, so:

2 + (x + 4), or x + 6 represents the hundred's digit.

These all sum up to 13, so write an expression to represent this:

x + (x + 4) + (x + 6) = 13

Combine like terms:

3x + 10 = 13

Subtract 10 from both sides:

3x = 3

Divide both sides by 3:

x = 1

Find the digits using the rules listed above:

Hundreds' digit: (1) + 6 = 7

Tenths' digit:  (1) + 4 = 5

Units' digit: 1 = 1

Therefore, the number is:

751.

Step-by-step explanation:

Consider the provided equation.

y=3 represents a vertical plane which is in xy plane.

Z=7 represents a horizontal plane which is parallel to xy plane

The both planes are perpendicular to each other and intersect.

y=3 and z=7 is the intersection of two plans, where the value of x is zero y=3 and z=7.

The set of points is (0,3,7) and the line is parallel to x axis.

Delicious77 [7]

Answer:

20 %

Step-by-step explanation:

% Increase = Increase/Original value × 100 %

Data:

 Original = $25

This year = $30

Calculations:

   Increase =  This year - original

                  =         30       -      25

                  =                   $5

% Increase = 5/25 × 100 %
