What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Paula earns a weekly salary of $890 plus a 5% commission. Last week, she sold $3250 worth of products.

The commission is the part of the sales you made that you get

A 5% commission means she gets 5% of what she sold

5% of 3250=0.05 times 3250=162.5

The gross pay will be calculated as,

salary+comission=gross pay (no tax)

890+162.5=$1052.50

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. the ratio 3/8 to 4/9 has a unit rate of 1/6 is false.

What is Ratio?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

The given ratio is  three by eight to four by nine

3/8 to 4/9

This can be written as 3/8 :4/9

and also we can write

(3/8)/(4/9)

When a fraction is divided by another fraction, the denominator fraction is multiplied by reciprocal to the numerator.

So

3/8×9/4

27/32

3/8 to 4/9 has a unit rate of 27/32 but not 1/6.

Hence the ratio 3/8 to 4/9 has a unit rate of 1/6 is false.

Answer:

The ratio 3/8 to 4/9 has a unit rate of 1/6 true or fals

Step-by-step explanation:

The ratio 3/8 to 4/9 has a unit rate of 1/6 true or fals

Answer:

  18

Step-by-step explanation:

A two-digit number (xy) will have the value 10x+y. The sum of its digits is x+y.

You want ...

  10x +y = 2(x +y)

  1 ≤ x ≤ 9

  0 ≤ y ≤ 9

The equation can be simplified to ...

  8x = y

The only single-digit values for x and y that satisfy the requirements are ...

  x = 1, y = 8

The two-digit number of interest is 18.

_____

Check

Its sum of digits is 1+8 = 9. 2×9 = 18.

_____

Comment on the relationship in the problem

Many of us learned our multiplication tables for 9s by remembering that the sum of digits of 9n was 9, and that the leading digit of the product was n-1.

Answer:

the statement is x=y/8 the number is 18

Step-by-step explanation:
